Hello, I'm setting up a new server and, again, seek for a decently secure (from a security specialist's POV) way to store and verify user passwords in a database. Additionally now, GDPR requires me to use a solid state-of-the-art solution. My OS is Ubuntu 20.04, Dovecot version 2.3.7, database backend with PostgreSQL 12. Obviously, storing the plaintext password is a terrible idea.

...erated hash values include the prefix $2b$, but our crypt library rejects these, only accepting hash formats with the prefix $2a$. Our current bcrypt java library (http://www.mindrot.org/projects/jBCrypt also https://github.com/jeremyh/jBCrypt) uses the modular crypt format (http://pythonhosted.org/passlib/modular_crypt_format.html) to store both the salt and the hash of the password. The python library we have selected uses bcrypt.c. In (http://www.openwall.com/lists/oss-security/2012/01/02/4), 'Alexander' describes that Christos Zoulas discovered a wrap-around error. This is also described...
