Crypt::PWSafe3 provides read/write access to Password Safe V3 database files.

Crypt::Password::Util is a crypt password utilities. Its crypt($str) works like Perl's crypt(), but automatically choose the appropriate crypt type and random salt. Will first choose SSHA512 with 64-bit random salt. If not supported by system, fall back to MD5-CRYPT with 32-bit random salt. If that is not supported, fall back to CRYPT. Its crypt_type($str) returns crypt type, or undef if $str does not look like a crypted password. Currently known types: CRYPT (traditional DES crypt), MD5-CRYPT (including Apache variant), SSHA256 (salted SHA256), SSHA512 (salted SHA512), and PLAIN-MD5. See also Authen::Passphrase which recognizes more encodings (but currently not SSHA256 and SSHA512).

This module implements Ueli Maurer's algorithm for generating large provable primes and secure parameters for public-key cryptosystems. The generated primes are almost uniformly distributed over the set of primes of the specified bitsize and expected time for generation is less than the time required for generating a pseudo-prime of the same size with Miller-Rabin tests. Detailed description and running time analysis of the algorithm can be found in Maurer's paper[1]. Crypt::Primes is a pure perl implementation. It uses Math::Pari for multiple precision integer arithmetic and number theoretic functions. Random numbers are gathered with Crypt::Random, a perl interface to /dev/u?random devices found on modern Unix operating systems.

Crypt::Rhash module is an object-oriented interface to the LibRHash library, allowing simultaneous calculation of several hash functions for a file or a text message. Resulting hash digest can be obtained in hexadecimal, BASE32, BASE64, raw binary format or as a magnet link.

Parse RSA keys for useful information

Crypt::Random::Seed is a simple mechanism to get strong randomness. The main purpose of this module is to provide a simple way to generate a seed for a PRNG such as Math::Random::ISAAC, for use in cryptographic key generation, or as the seed for an upstream module such as Bytes::Random::Secure. Flags for requiring non-blocking sources are allowed, as well as a very simple method for plugging in a source.

Crypt::Passwd::XS - Full XS implementation of common crypt() algorithms This module provides several common crypt() schemes as full XS implementations. It allows you to validate crypted passwords that were hashed using a scheme that the system's native crypt() implementation does not support.

The `unix_md5_crypt()' provides a crypt()-compatible interface to the rather new MD5-based crypt() function found in modern operating systems. It's based on the implementation found on FreeBSD 2.2.[56]-RELEASE. `apache_md5_crypt()' provides a function compatible with Apache's `.htpasswd' files. This was contributed by Bryan Hart <bryan@eai.com>.

Get weak or strong random data from pluggable sources

Crypt::Random::TESHA2 implements userspace voodoo entropy. You should use a proper O/S supplied entropy source such as /dev/random or the Win32 Crypt API.
