Detailed Description

Abstract password hash computation and verification class.

This class defines the interface for verifying a passwords against password hashes, or computing a new password hash for a password.

Member Function Documentation

virtual PasswordHash Wt::Auth::PasswordService::AbstractVerifier::hashPassword ( const WString password) const
pure virtual

Computes the password hash for a clear text password.

This must return a hash that can later be used to verify the user's password, but which avoids compromising the user's password in case of loss.

Implemented in Wt::Auth::PasswordVerifier.

virtual bool Wt::Auth::PasswordService::AbstractVerifier::needsUpdate ( const PasswordHash hash) const
pure virtual

Returns whether a password hash needs to be updated (recomputed).

A hash may need to be updated if it has been computed with a cryptographic method that is being disfavoured.

Implemented in Wt::Auth::PasswordVerifier.

virtual bool Wt::Auth::PasswordService::AbstractVerifier::verify ( const WString password,
const PasswordHash hash 
) const
pure virtual

Verifies a password against a hash.

This returns whether the given password matches with the user's credentials stored in the hash.

Implemented in Wt::Auth::PasswordVerifier.
