TLS Cipher Updates

This section gives detail on supported ciphers.

Oracle recommends the following ciphers, and includes them in the DEFAULT cipher list:

TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384
TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256
TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384
TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256
TLS_DHE_RSA_WITH_AES_256_GCM_SHA384
TLS_DHE_RSA_WITH_AES_128_GCM_SHA256

Oracle supports the following ciphers, but does not include them in the DEFAULT cipher list:

TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384
TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256
TLS_DHE_RSA_WITH_AES_128_CBC_SHA256
TLS_DHE_RSA_WITH_AES_256_CBC_SHA256
TLS_RSA_WITH_AES_256_CBC_SHA256
TLS_RSA_WITH_AES_256_GCM_SHA384
TLS_RSA_WITH_AES_128_CBC_SHA256
TLS_RSA_WITH_AES_128_CBC_SHA
TLS_RSA_WITH_3DES_EDE_CBC_SHA
TLS_RSA_WITH_AES_128_GCM_SHA256

Oracle supports the following ciphers for debugging purposes only:

TLS_RSA_WITH_NULL_SHA256 (debug only)
TLS_RSA_WITH_NULL_SHA (debug only)
TLS_RSA_WITH_NULL_MD5 (debug only)

Oracle supports the following ciphers, but considers them not secure. They are not included in the DEFAULT cipher-list, but they are included when you set the cipher-list attribute to ALL. Note that they trigger verify-config error messages.

TLS_DHE_RSA_WITH_AES_256_CBC_SHA
TLS_RSA_WITH_AES_256_CBC_SHA
TLS_DHE_RSA_WITH_AES_128_CBC_SHA
TLS_DHE_RSA_WITH_3DES_EDE_CBC_SHA

To configure TLS ciphers, use the cipher-list attribute in the tls-profile configuration element.

WARNING:

When you set tls-version to either tlsv1 or tlsv11 and you want to use ciphers that Oracle considers not secure, you must manually add them to the cipher-list attribute.

Note:

The default is TLSv1.2. Oracle supports TLS1.0 and TLS1.1 for backward compatibility only and they may be deprecated in the future.
