libghc-pwstore-fast-dev - 2.4.4-10+b1 main

To store passwords securely, they should be salted, then hashed with a
slow hash function. This library uses PBKDF1-SHA256, and handles all
the details. It uses the cryptohash package for speed; if you need a
pure Haskell library, pwstore-purehaskell has the exact same API, but
uses only pure Haskell. It is about 25 times slower than this package,
but still quite usable.
.
This package provides a library for the Haskell programming language.
