Detailed Description

A cryptographic hash function implemented using SHA1.

This hash function is only available if Wt was compiled with OpenSSL support.

This hash function is useful for creating token hashes, but should not be used for password hashes.

Member Function Documentation

std::string Wt::Auth::SHA1HashFunction::compute ( const std::string &  msg, const std::string &  salt  ) const

virtual

Computes the hash of a message + salt.

The message is usually an ASCII or UTF-8 string.

The salt and the computed hash are encoded in printable characters. This is usually ASCII-encoded (as for the UNIX crypt() functions) or could be Base64-encoded.

Implements Wt::Auth::HashFunction.

std::string Wt::Auth::SHA1HashFunction::name ( ) const

virtual

Returns the name for this hash function.

Returns "SHA1".
