Two new cipher suites using AES are available in Adaptive Server version 12.5.3:
TLS_RSA_WITH_AES_256_CBC_SHA
TLS_RSA_WITH_AES_128_CBC_SHA
AES is a FIPS-197 approved standard for symmetric encryption. The AES algorithm provides the strongest encryption available for Adaptive Server.
The AES algorithm and dependent cipher suites used in SSL are available by default in Adaptive Server 12.5.3 and Open Client 12.5.1. No action is required by users or administrators to use this algorithm unless algorithms are currently restricted client applications. If you have clients that currently restrict algorithms, you may want to consider using AES algorithm instead.
