Currently we only support validation of existing BCrypt password hashes. To be able to migrate a user's password to BCrypt, the implementation of the two methods encode and encodedCredential in the Typo3BCryptPasswordHashProvider class is required.
If we want to support custom parameters (which bcrypt version, salt length, etc), we would need to implement custom PasswordPolicyProvider as well.
Currently we only support validation of existing Argon2 password hashes. To be able to migrate a user's password to Argon2, the implementation of the two methods encode and encodedCredential in the ArgonPasswordHashProvider class is required.
If we want to support custom parameters (which argon version, salt length, etc), we would need to implement custom PasswordPolicyProvider as well.
