The following topics are covered:
Area: JCE
Synopsis: The Apple provider has been introduced, which implements a java.security.KeyStore that provides access to the Mac OS X Keychain. This is part of RFE JDK-7113349, the JDK port for Mac OS X. See the section The Apple Provider in Java Cryptography Architecture Oracle Providers Documentation
Area: Java Cryptography Extension
Synopsis: Public key certificates containing Elliptic Curve Cryptography (ECC) keys are parsed correctly by the SunPKCS11 JCE security provider on Solaris 11. See 7054637.
The Java SE 7 release adds the following features:
Elliptic Curve Cryptography (ECC): A new native provider has been added to the Java SE 7 release that provides several ECC-based algorithms (ECDSA/ECDH). For more information, see The SunEC Provider's Supported Algorithms section in the Java Cryptography Architecture Oracle Providers Documentation.
CertPath Algorithm Disabling: Weak cryptographic algorithms can now be disabled. For example, the MD2 digest algorithm is no longer considered secure. The Java SE 7 release provides a mechanism for denying the use of specific algorithms in certification path processing and TLS handshaking. See Appendix D: Disabling Cryptographic Algorithms in Java PKI Programmer's Guide and Disabled Cryptographic Algorithms in Java Secure Socket Extension (JSSE) Reference Guide for more information.
JSSE (SSL/TLS):
TLS 1.1: The SunJSSE provider now supports TLS 1.1 as described in RFC 4346. The most important update is protection against cipher block chaining (CBC) attacks.
TLS 1.2: The SunJSSE provider now supports TLS 1.2 as described in RFC 5246. Among other things, it specifies different internal hashing algorithms, adds new cipher suites, and contains improved flexibility, particularly for negotiation of cryptographic algorithms.
Weak cipher suites deprecated: Per RFC 4346, RFC 5246, and RFC 5469, some cipher suites have been made obsolete and should not be used. These obsolete suites are all disabled by default in SunJSSE. For details, consult the cipher lists in the section The SunJSSE Provider in Java Cryptography Architecture Oracle Providers Documentation.
Connection-sensitive trust management: Both trust managers and key managers now have the ability to examine parameters of the TLS connection, specifically the SSLSession under construction, during the handshake. For example, a trust manager might restrict the types of certificates used based on the list of valid signature algorithms.
HttpsURLConnection and HostnameVerifier), such verification can now be optionally performed at the TLS level.TLS renegotiation: Java SE supports RFC 5746, which fixes a renegotiation issue in the TLS protocol. See the section Transport Layer Security (TLS) Renegotiation Issue in Java Secure Socket Extension (JSSE) Reference Guide.
SSLv2Hello disabled by default on the client: In Java SE 7, SSLv2Hello is removed from the default enabled protocol list on the client.
Algorithm disabling: Weak cryptographic algorithms can now be disabled, as previously described.
Server Name Indication (SNI) for JSSE client: The Java SE 7 release supports the Server Name Indication (SNI) extension in the JSSE client. SNI is described in RFC 4366. This enables TLS clients to connect to virtual servers.
Tighter checking of EncryptedPreMasterSecret version numbers: Java SE 7 tightens version number checking during TLS 1.1 and TLS 1.2 handshaking. See Tighter Checking of EncryptedPreMasterSecret Version Numbers in Java Cryptography Architecture Oracle Providers Documentation for more information.
In addition, the following enhancements are added:
Area: Security
Standard/Platform: Java SE 7
Synopsis: Security algorithm requirement have been defined
for Java SE 7 that provide a list of algorithms that all
implementations of Java SE 7 must support. The class summary of
applicable classes (ex: java.security.Signature) has been
updated to include the implementation requirements. Also, all of
the requirements are listed in the
Implementation Requirements section of the Standard Algorithms
document.
RFE: 5001004
Area: API: JSSE
Standard/Platform: Java SE 7
Synopsis: In previous releases, except for the default
algorithm, there was no standard algorithm name for
KeyManagerFactory. In the Java SE 7 release, "PKIX" is
exported as the standard algorithm name for
KeymanagerFactory. The "PKIX" KeyManagerFactory
algorithm is defined as:
A factory for X509ExtendedKeyManagers that manages X.509
certificate-based key pairs for the local side authentication
according to the rules defined by the IETF PKIX working group in
RFC 3280 or its successor. The KeyManagerFactory must
support initialization using the class
javax.net.ssl.KeyStoreBuilderParameters.
RFE: 7022855
Area: API: JSSE
Standard/Platform: Java SE 7
Synopsis: Support for TLS 1.2 has been added to the SunJSSE
provider.
RFE: 6916074
Area: JSSE
Standard/Platform: JDK 7
Synopsis: The TLS renegotiation fix has been implemented.
Please see
TLS/SSLv3 Renegotiation Vulnerability Explained and
Understanding the TLS Renegotiation Attack for more information.
Area: JSSE

extension has been added to the JSSE client in the SunJSSE
provider.
RFE: 6985179
Area: SASL
Standard/Platform: JDK 7
Synopsis: NTLM is now supported as a SASL mechanism on both
the client and server side. Only the authentication layer is
implemented, and there is no privacy or integrations protection in
communication.
RFE: 6911951
Area: Security
Standard/Platform: JDK 7
Synopsis: The implementation of PKIX has been enhanced to
include an option to reject certificates if the corresponding key
is not strong enough, for example MD2 hash functions or any RA key
with key size less than 1024.
RFE: 6792180
Area: API: JSSE
Standard/Platform: JDK 7
Synopsis: Support for TLS 1.1 has been added to the SunJSSE
provider, and the SSLv2Hello "pseudo protocol" is no longer active
by default in the SunJSSE provider.
RFE: 4873177

Standard/Platform: JDK 7
Synopsis: Java now reads a keytab file whenever that keytab
file changes. The file can be empty or nonexistent when the
application that uses the file is started.
Area: JGSS
Standard/Platform: JDK 7
Synopsis: A default configuration file is now provided for
JGSS with default krb5.conf settings for Windows and *nix
systems. This makes deploying a JGSS/krb5 program very easy,
especially for deploying Java applets.
RFE: 6483218,

Standard/Platform: JDK 7
Synopsis: SunPKCS11 provider now supports Raw RSA
encryption, for example,
Cipher.getInstance("RSA/ECB/NoPadding") calls, when the
underlying PKCS11 library supports CKM-RSA_X_509 mechanism. In
addition, SunPKCS11 provider recognizes "RSA" as an alias for the
"RSA/ECB/PKCS1Padding" transformation when requesting a
Cipher object.
RFE: 6994008
Area: JCE
Standard/Platform: JDK 7
Synopsis: The SunPKCS11 provider now supports ECB, CBC modes
with PKCS5Padding for certain block ciphers. To be more specific,
it supports the following transformations for
Cipher.getInstance(...) calls when the corresponding
PKCS11 mechanism is supported by the underlying PKCS11 library:
DES, DESede, AES, and Blowfish with CBC mode and PKCS5Padding
DES, DESede, AES with ECB mode and PKCS5Padding

Synopsis: Given that the relevant Solaris bug (i.e. 6306708
"CKM_SSL3_KEY_AND_MAC_DERIVE returns incorrect cipher keys for
exportable ciphersuites") has been addressed in the Solaris 10
update 5 release, the SunPKCS11 provider no longer disables the
following two mechanisms by default:
CKM_SSL3_KEY_AND_MAC_DERIVE
CKM_TLS_KEY_AND_MAC_DERIVE
