3.1.2. Updated keytool to create AKID from SKID for issuing certificate as specified by RFC 5280
The gencert command of the keytool utility has been updated to create AKID from the SKID for issuing certificate as specified by RFC 5280.
For more information, see JDK-8261922.
3.1.3. Added ChaCha20 and Poly1305 TLS cipher suites
The new TLS cipher suites using the ChaCha20-Poly1305 algorithm are added to JSSE. These cipher suites are enabled by default. The TLS_CHACHA20_POLY1305_SHA256 cipher suite is available for TLS 1.3.
The following cipher suites are available for TLS 1.2:
-
TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305_SHA256 -
TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305_SHA256 -
TLS_DHE_RSA_WITH_CHACHA20_POLY1305_SHA256
For more information, see JDK-8210799.
3.1.4. Updated the default enabled cipher suites preference
