Entropy is the measure of randomness the operating system collects to seed cryptographic random number generators (RNGs). Strong entropy is essential for secure key generation, salts, nonces, session identifiers, and any operation that relies on unpredictability. Inadequate entropy can make cryptographic outputs guessable and weaken security. OpenEdge uses entropy to:
  • Generate encryption keys, IVs, and nonces.
  • Create password hashes and random salts via ABL security APIs.
  • Seed Java SecureRandom for OpenEdge Java OpenClient in FIPS or non-FIPS mode.
