you can modify the currently used encryption types in vas.conf by using the following command line:
# /opt/quest/bin/vastool configure vas libdefaults default_etypes "list-of-enctypes"
Be sure to include the enctypes that you want above, and do not use "list-of-enctypes". If you do, it will change the value in vas.conf to this:
[libdefaults]
default_etypes = "list-of-enctypes"
Example enabling RC4 and AES:
# /opt/quest/bin/vastool configure vas libdefaults default_etypes aes256-cts-hmac-sha1-96 aes128-cts-hmac-sha1-96 arcfour-hmac-md5
Changes are immediate, and the vasd process does not need a restart.
