Password hashing does a one-way, permanent transformation of the passwords of the Control Room users, inline with standard password management practices.

Control Room passwords are concatenated with a salt and then hashed using the Password-Based Key Derivation Function (PBKDF2) with HMAC SHA512 algorithm before being stored in the database.

• The salt is 256-bits in size and randomly generated by a cryptographically secure PRNG.
• The HMAC SHA512 algorithm is used for hashing and provides additional security over traditional approaches.
  • A keyed hash provides protection against hash length extension attacks.
  • SHA 512-bit key is larger than the commonly used SHA 256-bit key.
• The key used for the HMAC is from the secure PBKDF2.
• Hashing is done for 100,000 rounds (based on NIST recommendations).

Every time a Bot Creator or Bot Runner authenticates against Control Room, its credentials are authenticated against the hashed credentials.
