Sel.Scrypt

Introduction

This API is used for hashing and verifying passwords using the Scrypt algorithm. This module is provided for interoperability with other applications. If you do not need to use Scrypt specifically, use Sel.Hashing.Password.

Password Hashing and Verifying.

scryptHashPassword :: StrictByteString -> IO ScryptHash

Hash the password with the Scrypt algorithm and a set of pre-defined parameters.

The hash is encoded in a human-readable format that includes:

• The result of a memory-hard, CPU-intensive hash function applied to the password;
• The automatically generated salt used for the previous computation;
• The other parameters required to verify the password, including the algorithm identifier, its version, opslimit, and memlimit.

Since: 0.0.1.0

scryptVerifyPassword :: StrictByteString -> ScryptHash -> IO Bool

Verify a hashed password against a password verification string. This returns True if successful.

Since: 0.0.1.0

Conversion

scryptHashToByteString :: ScryptHash -> StrictByteString

Convert a ScryptHash to a binary StrictByteString.

Since: 0.0.1.0

scryptHashToText :: ScryptHash -> Text

Convert a ScryptHash to a hexadecimal-encoded Text.

Since: 0.0.1.0

asciiTextToScryptHash :: Text -> ScryptHash

Convert an ASCII-encoded password hash to a ScryptHash

This function does not perform ASCII validation.

Since: 0.0.1.0

asciiByteStringToScryptHash :: StrictByteString -> ScryptHash

Convert an ASCII-encoded password hash to a ScryptHash

This function does not perform ASCII validation.
