To provide extra protection against brute-force attacks, Pega Platform uses salted bcrypt as the default hashing algorithm for Password property types. Bcrypt uses a modified key setup algorithm that requires a long time to process. Key strengthening makes a password more secure against brute-force attacks, meaning potential attackers must spend a substantial amount of time testing every possible key.
Bcrypt is an adaptive hashing algorithm based on the Blowfish symmetric block cipher cryptographic algorithm.
Changing the encryption algorithm
For on-premises deployments, ensure that you are using the salted bcrypt algorithm by
removing all cryptographic‑related configuration settings from the
Convert preexisting password hashes to use the new algorithm by editing or creating the following Dynamic System Settings in Dev Studio:
