Specifies the ciphers that can be used on UNIX and z/OS for OpenSSL.
Client: | Optional |
Server: | Optional |
Valid in: | Configuration file, command line |
Categories: | Communications: Networking and Encryption |
System Administration: Security | |
Operating environment: | UNIX and z/OS |
Notes: | This environment variable is available in all SAS 9.3 and SAS 9.4 versions of software if hot fixes are applied. |
This environment variable must be set before TLS or SSL are loaded. It cannot be changed after TLS or SSL is loaded. You must set the environment variable before the SAS/CONNECT spawner is started and before SAS is started on the client. | |
Tip: | You can also define SET commands for Windows by using the System Properties dialog box that you access from the Control Panel. |
See: | Defining Environment Variables in UNIX Environments in SAS Companion for UNIX Environments, TKMVSENV File in SAS Companion for z/OS |
Examples: | Export the environment variable on UNIX hosts for
the Bourne Shell:export SAS_SSL_CIPHER_LISTSS=TLS1.2 |
Set the environment variable on UNIX hosts for the
C Shell environment: SETENV SAS_SSL_CIPHER_LISTS HIGH |
|
Set the environment variable at SAS invocation for
UNIX hosts:-set SAS_SSL_CIPHER_LISTS 3DES:RC2" |
|
Set the environment variable on Windows hosts SET SAS_SSL_CIPHER_LISTS SHA256 |
The SAS_SSL_CIPER_LIST environment variable specifies the ciphers that can be used on UNIX and z/OS for OpenSSL. Refer to the OpenSSL Ciphers document to see how to format the openssl-cipher-list and for a complete list of the ciphers that work with your TLS or SSL version.
