Problem Note 70905: Support for the 2048 and 4096 key lengths with AES encryption on z/OS
 |  |  |  |  |
Support for the 2048 and 4096 key lengths with AES encryption on z/OS has been added with the associated hot fix.
With the associated hot fix, the default key length is 4096. During the client or server connections, the key length that is used is negotiated.
To set a different key length that is used on z/OS, set the SAS environment variable SAS_RSA_BIT_LENGTH to 1024 or 2048.
For example, in the TKMVSENV file, set the key length to the following:
SAS_RSA_BIT_LENGTH=2048
Prior to this enhancement, the key length that could be used with SAS on z/OS was only 1024.
