On Linux Systems

You can enforce SHA-384 after you install BigFix V11 or upgrade it to V11, by running the following command as super user:

./BESAdmin.sh -securitysettings -sitePvkLocation=<path+license.pvk> 
-sitePvkPassword=mypassw0rd -requireSHA384Signatures
Note: The notation <path+license.pvk> used in the command syntax stands for path_to_license_file/license.pvk.
The full syntax of the ./BESAdmin.sh -securitysettings is the following:
./BESAdmin.sh -securitysettings -sitePvkLocation=<path+license.pvk> 
   [-sitePvkPassword=<password>]
   { -status | {-requireSHA384Signatures |-allowSHA256Signatures } 
   | {-requireSHA256Downloads|-allowSHA1Downloads} | {requireTLS13 | -allowTLS12 ] } }
where:
status
Shows the status of the security settings in your BigFix environment.
Example:
./BESAdmin.sh -securitysettings -sitePvkLocation=/root/backup/license.pvk 
-sitePvkPassword=mypassw0rd -status

requireSHA384Signatures | allowSHA256Signatures
Enables or disables the security option that adopts the SHA-384 cryptographic digest algorithm for all digital signatures.
requireSHA256Downloads | allowSHA1Downloads
Ensures that data has not changed after you download it using the SHA256 | SHA1 algorithm.
requireTLS13 | allowTLS12
With this option, you can require the use of TLS 1.3 for all HTTPS communication.
