OCaml-safepass is a library offering facilities for the safe storage of
user passwords. By "safe" we mean that passwords are salted and hashed
using the Bcrypt algorithm. Salting prevents rainbow-table based
attacks, whereas hashing by a very time-consuming algorithm such as
Bcrypt renders brute-force password cracking impractical.
OCaml-safepass's obvious usage domain are web applications, though it does not
depend on any particular framework. Internally, OCaml-safepass binds to the C
routines from Openwall's Crypt_blowfish. However, it would be
incorrect to describe OCaml-safepass as an OCaml binding to Crypt_blowfish,
because the API it exposes is higher-level and more compact than that offered
by Crypt_blowfish. Moreover, OCaml-safepass's API takes advantage of OCaml's
type-system to make usage mistakes nearly impossible.
OCaml-safepass has no external dependencies. Note that it bundles
the Public Domain licensed
C modules from Openwall's Crypt_blowfish.
Building and installing
OCaml-safepass is available in OPAM, which is the recommended installation
method. If you wish to compile it yourself manually, note that the build system
uses Dune. You can use the customary
make to build OCaml-safepass, and
make doc to generate the API documentation.
OCaml-safepass is distributed under the terms of the GNU LGPL version 2.1 with
the usual OCaml linking exception. See LICENSE file for full license text.
