/// tip

pwdlib also supports the bcrypt hashing algorithm but does not include legacy algorithms - for working with outdated hashes, it is recommended to use the passlib library.

For example, you could use it to read and verify passwords generated by another system (like Django) but hash any new passwords with a different algorithm like Argon2 or Bcrypt.

And be compatible with all of them at the same time.
