Semantics
keystore_management_clauses
Use these clauses to perform the following keystore management operations:
-
Create a software keystore
-
Open and close a software keystore or a hardware keystore
-
Back up a password-protected software keystore
-
Change the password of a password-protected software keystore
-
Merge two existing software keystores into a new password-protected software keystore
-
Merge one existing software keystore into an existing password-protected software keystore
-
Isolate the keystore of a Pluggable Database (PDB) from the Container Database (CDB) so that the PDB can manage its own keystore.
-
Unite the keystore of a PDB with the CDB.
create_keystore
This clause lets you create the following types of software keystores: password-protected software keystores and auto-login software keystores. To issue this clause in a multitenant environment, you must be connected to the root.
CREATE KEYSTORE
Specify this clause to create a password-protected software keystore.
-
For
keystore_location
, specify the full path name of the software keystore directory. The keystore will be created in this directory in a file namedewallet.p12
. This clause is optional if theWALLET_ROOT
parameter has been set. Refer to Oracle Database Advanced Security Guide to learn how to determine the software keystore directory for your system. -
Use the
IDENTIFIED
BY
clause to set the password for the keystore. Refer to "Notes on Specifying Keystore Passwords" for more information.
CREATE [ LOCAL ] AUTO_LOGIN KEYSTORE
Specify this clause to create an auto-login software keystore. An auto-login software keystore is created from an existing password-protected software keystore. The auto-login keystore has a system-generated password. It is stored in a PKCS#12-based file named cwallet.sso
in the same directory as the password-protected software keystore.
-
By default, Oracle creates an auto-login keystore, which can be opened from computers other than the computer on which the keystore resides. If you specify the
LOCAL
keyword, then Oracle Database creates a local auto-login keystore, which can be opened only from the computer on which the keystore resides. -
For
keystore_location
, specify the full path name of the directory in which the existing password-protected software keystore resides. The password-protected software keystore can be open or closed. -
Use the
IDENTIFIED
BY
clause to specify the password for the existing password-protected software keystore. Refer to "Notes on Specifying Keystore Passwords" for more information.
Restriction on Creating Keystores
You can create at most one password-protected software keystore and one auto-login software keystore, either local or not, in any single directory.
See Also:
Oracle Database Advanced Security Guide for more information on creating software keystores
open_keystore
This clause lets you open a password-protected software keystore or a hardware keystore.
Note:
You do not need to use this clause to open auto-login and local auto-login software keystores because they are opened automatically when they are required—that is, when the master encryption key is accessed.
-
The
FORCE
KEYSTORE
clause is useful when opening a keystore in a PDB. It ensures that the CDB root keystore is open before opening the PDB keystore. Refer to "Notes on the FORCE KEYSTORE Clause" for more information. -
Use the
IDENTIFIED
BY
clause to specify the password for the keystore. Refer to "Notes on Specifying Keystore Passwords" for more information. -
The
CONTAINER
clause applies when you are connected to a CDB.If the current container is a pluggable database (PDB), then specify
CONTAINER
=
CURRENT
to open the keystore in the PDB. The keystore must be open in the root before you open it in the PDB.If the current container is the root, then specify
CONTAINER
=
CURRENT
to open the keystore in the root, or specifyCONTAINER
=
ALL
to open the keystore in the root and in all PDBs.If you omit this clause, then
CONTAINER
=
CURRENT
is the default.
See Also:
Oracle Database Advanced Security Guide for more information on opening password-based software keystores and hardware keystores
close_keystore
This clause lets you close a password-protected software keystore, an auto-login software keystore, or a hardware keystore. Closing a keystore disables all encryption and decryption operations. Any attempt to encrypt or decrypt data or access encrypted data results in an error.
-
To close a password-protected software keystore or a hardware keystore, specify the
IDENTIFIED
BY
clause. Refer to "Notes on Specifying Keystore Passwords" for more information. -
To close an auto-login keystore, do not specify the
IDENTIFIED
BY
clause. Before you close an auto-login keystore, check theWALLET_TYPE
column of theV$ENCRYPTION_WALLET
view. If it returnsAUTOLOGIN
, then you can close the keystore. Otherwise, if you attempt to close the keystore, then an error occurs. -
The
CONTAINER
clause applies when you are connected to a CDB.If the current container is a PDB, then specify
CONTAINER
=
CURRENT
to close the keystore in the PDB.If the current container is the root, then the
CONTAINER
=
CURRENT
andCONTAINER
=
ALL
clauses have the same effect; both clauses close the keystore in the root and in all PDBs.If you omit this clause, then
CONTAINER
=
CURRENT
is the default.
See Also:
Oracle Database Advanced Security Guide for more information on closing keystores
backup_keystore
This clause lets you back up a password-protected software keystore. The keystore must be open.
-
By default, Oracle Database creates a backup file with a name of the form
ewallet_
timestamp
.p12
, wheretimestamp
is the file creation timestamp in UTC format. The optionalUSING
'
backup_identifier
'
clause lets you specify a backup identifier which is added to the backup file name. For example, if you specify a backup identifier of'Backup1'
, then Oracle Database creates a backup file with a name of the formewallet_
timestamp
_Backup1.p12
. -
The
FORCE
KEYSTORE
clause enables this operation even if the keystore is closed. Refer to "Notes on the FORCE KEYSTORE Clause" for more information. -
Use the
IDENTIFIED
BY
clause to specify the password for the keystore. Refer to "Notes on Specifying Keystore Passwords" for more information. -
The optional
TO
'keystore_location
' clause lets you specify the directory in which the backup file is created. If you omit this clause, then the backup is created in the same directory as the keystore that you are backing up.
See Also:
Oracle Database Advanced Security Guide for more information on backing up password-based software keystores
alter_keystore_password
This clause lets you change the password for a password-protected software keystore. The keystore must be open.
-

, specify the new password for the keystore. Refer to "Notes on Specifying Keystore Passwords" for more information. -
The optional
WITH
BACKUP
clause instructs the database to create a backup of the keystore before changing the password. Refer to "Notes on the WITH BACKUP Clause" for more information.
See Also:
Oracle Database Advanced Security Guide for more information on changing a password-based software keystore password
merge_into_new_keystore
This clause lets you merge two software keystores into a new keystore. The keys and attributes in the two constituent keystores are added to the new keystore. The constituent keystores can be password-based or auto-login (including local auto-login) software keystores; they can be open or closed. The new keystore is a password-protected software keystore. It is in a closed state when the merge completes. Any or none of the keystores specified in this clause can be the keystore configured for use by the database.
-
For
keystore1_location
, specify the full path name of the directory in which the first keystore resides. -
Specify
IDENTIFIED
BY
keystore1_password
only if the first keystore is a password-based software keystore. Refer to "Notes on Specifying Keystore Passwords" for more information. -
For
keystore2_location
, specify the full path name of the directory in which the second keystore resides. -

merge_into_existing_keystore
This clause lets you merge a software keystore into another existing software keystore. The keys and attributes in the keystore from which you merge are added to the keystore into which you merge. The keystore from which you merge can be a password-protected or auto-login (including local auto-login) software keystore; it can be open or closed. The keystore into which you merge must be a password-based software keystore. It can be open or closed when the merge begins. However, it will be in a closed state when the merge completes. Either or neither of the keystores specified in this clause can be the keystore configured for use by the database.
-
For
keystore1_location
, specify the full path name of the directory in which the keystore from which you merge resides. -
Specify
IDENTIFIED
BY
keystore1_password
only if the keystore from which you merge is a password-based software keystore. -

See Also:
Oracle Database Advanced Security Guide for more information on merging software keystores
isolate_keystore
Pluggable Databases (PDB) within a Container Database (CDB) can create and manage their own keystore. The isolate_keystore
clause allows a tenant to:
-
Manage its Transparent Data Encryption keys independently from those of the CDB.
-
Create a password for its independent keystore.
Within the CDB environment you can choose how the keys of a given PDB are protected. PDBs can either protect their keys with an independent password, or use the united password of the CDB.
-
Use the
IDENTIFIED
BY
clause to specify the password for the keystore. -
The
isolated_keystore_password
refers to the independent password of the PDB keystore. -
The
FORCE
KEYSTORE
clause enables this operation even if the keystore is closed. Refer to "Notes on the FORCE KEYSTORE Clause" for more information. -
The

FORCE Clause with isolate_keystore
The FORCE
clause of the ADMINISTER KEY MANAGEMENT FORCE ISOLATE KEYSTORE
command is used when a clone of the PDB is using the master key being isolated. This command copies the keys from the CDB keystore into the isolated PDB keystore. For example:
ADMINISTER KEY MANAGEMENT
FORCE ISOLATE KEYSTORE
IDENTIFIED BY <isolated_keystore_password>
FROM ROOT KEYSTORE
[FORCE KEYSTORE]
IDENTIFIED BY [EXTERNAL STORE | <united_keystore_password>]
[WITH BACKUP [USING <backup_identifier>]
unite_keystore
The unite_keystore
clause allows a PDB that was independently managing its keystore to change its keystore management mode to united. In united mode CDB$ROOT
keystore password is used to manage PDBs within the CDB.
-
Use the
IDENTIFIED
BY
clause to specify the password for the keystore. -
The
isolated_keystore_password
refers to the independent password of the PDB keystore. -
The

set_key
This clause creates a new master encryption key and activates it. You can use this clause to create the first master encryption key in a keystore or to rotate (change) the master encryption key. If a master encryption key is active when you use this clause, then it is deactivated before the new master encryption key is activated. The keystore that contains the key can be a password-protected software keystore or a hardware keystore. The keystore must be open.
Specify the desired value for your TDE Master Key ID (MKID
) and desired value of the TDE Master Encryption Key (MK
) to create your own TDE Master Encryption Key.
-
In TDE encrypted databases, the TDE Master Key ID(
MKID
) is used to keep track of which TDE Master Encryption Key is in use. TheMKID:MK
option allows both theMKID
and theMK
to be specified. -
If only the
MK
is specified, the database generates aMKID
for you, so that you can keep track of the TDE Master Encryption Key having theMK
value that you specified. -
If the
MKID
is invalid, for example if it is the wrong length, or if it is a string of zeroes, you will see the following error:ORA-46685: invalid master key identifier or master key value.
-
If the
MKID
you specified is the same as theMKID
of an existing TDE Master Encryption Key in the keystore, you will see the following error:ORA-46684: master key identifier exists in the keystore.
-
If either the
MKID
or theMK
is invalid, you will see the following error:ORA-46685: invalid master key identifier or master key value.
-
You can specify the
MKID:MK
option for theset_key
clause andcreate_key
clause.

See Also:
Oracle Database Advanced Security Guide for more information on adding, updating, and deleting secrets
add_update_secret
This clause lets you add a secret to a keystore or update an existing secret in a keystore. The keystore must be open.
-
Specify
ADD
to add a secret to a keystore. -
Specify
UPDATE
to update an existing secret in a keystore. -
For
secret
, specify the secret to be added or updated. The secret is an alphanumeric string. Enclose the secret in single quotation marks. -
For
client_identifier
, specify an alphanumeric string used to identify the secret. Encloseclient_identifier
in single quotation marks. This value is case-sensitive. -
Specify the optional
USING
TAG
clause to associate a tag tosecret
. Thetag
is an optional, user-defined descriptor for the secret. Enclose the tag in single quotation marks. You can view secret tags by querying theSECRET_TAG
column of theV$CLIENT_SECRETS
view. -
The
FORCE
KEYSTORE
clause enables this operation even if the keystore is closed. Refer to "Notes on the FORCE KEYSTORE Clause" for more information. -
Use the
IDENTIFIED
BY
clause to specify the password for the keystore. Refer to "Notes on Specifying Keystore Passwords" for more information. -
Specify the
WITH
BACKUP
clause, and optionally theUSING
'
backup_identifier
'
clause, to create a backup of the keystore before adding or updating the secret in a password-based software keystore. Refer to "Notes on the WITH BACKUP Clause" for more information.
delete_secret
This clause lets you delete a secret from a keystore. The keystore must be open.
-
For
client_identifier
, specify an alphanumeric string used to identify the secret. Encloseclient_identifier
in single quotation marks. You can view client identifiers by querying theCLIENT
column of theV$CLIENT_SECRETS
view. -
The
FORCE
KEYSTORE
clause enables this operation even if the keystore is closed. Refer to "Notes on the FORCE KEYSTORE Clause" for more information. -
Use the
IDENTIFIED
BY
clause to specify the password for the keystore. Refer to "Notes on Specifying Keystore Passwords" for more information. -
Specify the
WITH
BACKUP
clause, and optionally theUSING
'
backup_identifier
'
clause, to create a backup of the keystore before deleting the secret from a password-based software keystore. Refer to "Notes on the WITH BACKUP Clause" for more information.
Notes on the USING TAG Clause
Many ADMINISTER
KEY
MANAGEMENT
operations include the USING
TAG
clause, which lets you associate a tag to an encryption key. The tag
is an optional, user-defined descriptor for the key. It is a character string enclosed in single quotation marks.
You can view encryption key tags by querying the TAG
column of the V$ENCRYPTION_KEYS
view.
Notes on the FORCE KEYSTORE Clause
When a auto-login wallet exists, the FORCE KEYSTORE
clause enables a keystore operation even if the keystore is closed.. The behavior of this clause depends on whether you are connected to a non-CDB, a CDB root, or a PDB.
-
When you are connected to a non-CDB:
-
If the password-protected software or hardware keystore is closed, then the database opens the password-protected software or hardware keystore while the operation is performed and leaves it open, and then updates the auto-login keystore, if one exists, with the new information.
-
If the auto-login keystore is open, then the database opens the password-protected software or hardware keystore temporarily while the operation is performed and updates the auto-login keystore with the new information, without switching out the auto-login keystore.
-
If the password-protected software or hardware keystore is open, then the
FORCE
KEYSTORE
clause is not necessary and has no effect.
-
-
When you are connected to the CDB root:
-
To perform an operation on the CDB root keystore (
CONTAINER=CURRENT
), the CDB root keystore must be open. Therefore, the behavior described for a non-CDB applies to the CDB root. -
To perform an operation on the CDB root keystore and all PDB keystores (
CONTAINER=ALL
), the CDB root keystore and all PDB keystores must be open. Therefore, the behavior described for a non-CDB applies to the CDB root and each PDB.
-
-
When you are connected to a PDB:
-
To perform an operation on a PDB keystore, the CDB root keystore and the keystore for that PDB must be open. Therefore, the behavior described for a non-CDB applies to the CDB root and that PDB.
-
Notes on Specifying Keystore Passwords
Specify keystore passwords as follows:
-
For a password-protected software keystore, specify the password as a character string. You can optionally enclose the password in double quotation marks. Quoted and nonquoted passwords are case sensitive. Keystore passwords adhere to the same rules as database user passwords. Refer to the BY password clause of
CREATE
USER
for the complete details. -
For a hardware keystore, specify the password as a string of the form
"
user_id
:
password
"
where:-
user_id
is the user ID created for the database using the HSM management interface -
password
is the password created for the user ID using the HSM management interface
Enclose the
user_id
:
password
string in double quotation marks ("
"
) and separateuser_id
andpassword
with a colon (:
). -
-
If you specify
EXTERNAL
STORE
, then the database uses the keystore password stored in the external store to perform the operation. This feature enables you to store the password in a separate location where it can be centrally managed and accessed. To use this functionality, you must first set theEXTERNAL_KEYSTORE_CREDENTIAL_LOCATION
initialization parameter to a location where the keystore password will be stored. Refer to Oracle Database Advanced Security Guide for more information on configuring an external store for a keystore password.
Notes on the WITH BACKUP Clause
Many ADMINISTER
KEY
MANAGEMENT
operations include the WITH
BACKUP
clause. This clause applies only to password-protected software keystores. It indicates that the keystore must be backed up before the operation is performed. Therefore, you must either specify the WITH
BACKUP
clause when performing the operation, or issue the ADMINISTER
KEY
MANAGEMENT
backup_clause
statement immediately before performing the operation.
When you specify the WITH
BACKUP
clause, Oracle Database creates a backup file with a name of the form ewallet_
timestamp
.p12
, where timestamp
is the file creation timestamp in UTC format. The backup file is created in the same directory as the keystore you are backing up.
The optional USING
'
backup_identifier
'
clause lets you specify a backup identifier, which is added to the backup file name. For example, if you specify a backup identifier of 'Backup1'
, then Oracle Database creates a backup file with a name of the form ewallet_
timestamp
_Backup1.p12
.
The WITH
BACKUP
is mandatory for password-protected software keystores, but optional for hardware keystores.
Examples
Creating a Keystore: Examples
The following statement creates a password-protected software keystore in directory /etc/ORACLE/WALLETS/orcl
:
ADMINISTER KEY MANAGEMENT
CREATE KEYSTORE '/etc/ORACLE/WALLETS/orcl'
IDENTIFIED BY password;

and the backup file name contains the tag hr.emp_keystore
.
ADMINISTER KEY MANAGEMENT
BACKUP KEYSTORE USING 'hr.emp_keystore'
IDENTIFIED BY password
TO '/etc/ORACLE/KEYSTORE/DB1/';
Changing a Keystore Password: Example
The following statement changes the password for a password-protected software keystore. It also creates a backup of the keystore, with the tag pwd_change
, before changing the password.
ADMINISTER KEY MANAGEMENT ALTER KEYSTORE PASSWORD IDENTIFIED BY old_password SET new_password WITH BACKUP USING 'pwd_change';
Merging Two Keystores Into a New Keystore: Example
The following statement merges an auto-login software keystore with a password-protected software keystore to create a new password-protected software keystore at a new location:
ADMINISTER KEY MANAGEMENT MERGE KEYSTORE '/etc/ORACLE/KEYSTORE/DB1' AND KEYSTORE '/etc/ORACLE/KEYSTORE/DB2' IDENTIFIED BY existing_keystore_password INTO NEW KEYSTORE '/etc/ORACLE/KEYSTORE/DB3' IDENTIFIED BY new_keystore_password;
Merging a Keystore Into an Existing Keystore: Example
The following statement merges an auto-login software keystore into a password-protected software keystore. It also creates a backup of the password-protected software keystore before performing the merge.
ADMINISTER KEY MANAGEMENT
MERGE KEYSTORE '/etc/ORACLE/KEYSTORE/DB1'
INTO EXISTING KEYSTORE '/etc/ORACLE/KEYSTORE/DB2'
IDENTIFIED BY existing_keystore_password
WITH BACKUP;
Creating and Activating a Master Encryption Key: Examples
The following statement creates and activates a master encryption key in a password-protected software keystore. It encrypts the key using the SEED128
algorithm. It also creates a backup of the keystore before creating the new master encryption key.
ADMINISTER KEY MANAGEMENT
SET KEY USING ALGORITHM 'SEED128'
IDENTIFIED BY password
WITH BACKUP;
The following statement creates a master encryption key in a password-protected software keystore, but does not activate the key. It also creates a backup of the keystore before creating the new master encryption key.
ADMINISTER KEY MANAGEMENT
CREATE KEY USING TAG 'mykey1'
IDENTIFIED BY password
WITH BACKUP;
The following query displays the key identifier for the master encryption key that was created in the previous statement:
SELECT TAG, KEY_ID FROM V$ENCRYPTION_KEYS WHERE TAG = 'mykey1'; TAG KEY_ID --- ---------------------------------------------------- mykey1 ARgEtzPxpE/Nv8WdPu8LJJUAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
The following statement activates the master encryption key that was queried in the previous statement. It also creates a backup of the keystore before activating the new master encryption key.
ADMINISTER KEY MANAGEMENT
USE KEY 'ARgEtzPxpE/Nv8WdPu8LJJUAAAAAAAAAAAAAAAAAAAAAAAAAAAAA'
IDENTIFIED BY password
WITH BACKUP;
Setting a Key Tag: Example
This example assumes that the keystore is closed. The following statement temporarily opens the keystore and changes the tag to mykey2
for the master encryption key that was activated in the previous example. It also creates a backup of the keystore before changing the tag.
