  title "PostgreSQL must implement NIST FIPS 140-2 validated cryptographic
  modules to generate and validate cryptographic hashes."
  desc  "Use of weak or untested encryption algorithms undermines the purposes
  of utilizing encryption to protect data. The application must implement
  cryptographic modules adhering to the higher standards approved by the federal
  government since this provides assurance they have been tested and validated.
  For detailed information, refer to NIST FIPS Publication 140-2, Security
  Requirements For Cryptographic Modules. Note that the product's cryptographic
  modules must be validated and certified by NIST as FIPS-compliant."
