I am a new maintainer of PostgreSQL in Fedora and RHEL. Currently, I am solving usage SHA-1 for key-derivation in pgcrypto (the s2k-digest-algo). In the documentation, I have found that there are options SHA-1 or MD5. Unfortunately, none of these algorithms are FIPS compliant. So I would like to ask if exists a possibility to add or enable support for some type of stronger hash algorithm?
