This Perl module provides support for the HTTPS protocol under LWP, to allow an LWP::UserAgent object to perform GET, HEAD, and POST requests over encrypted socket connections. Please see LWP for more information on POST requests. The "Crypt::SSLeay"...

This module implements Net::SSLeay based random number generation for Crypt::Random::Source. Net::SSLeay does not wrap the SSL api, and "RAND_bytes" is documented as being cryptographically strong, so Crypt::Random::Source::Strong::SSLeay is also pro...

A simple implementation of the RC4 algorithm, developed by RSA Security, Inc. Here is the description from RSA's website: RC4 is a stream cipher designed by Rivest for RSA Data Security (now RSA Security). It is a variable key-size stream cipher with...

This module is a Perl-only implementation of the cryptographic cipher block chaining mode (CBC). In combination with a block cipher such as DES or IDEA, you can encrypt and decrypt messages of arbitrarily long length. The encrypted messages are compa...

This module implements the Argon2 key derivation function, which is suitable to convert any password into a cryptographic key. This is most often used to for secure storage of passwords but can also be used to derive a encryption key from a password....

Scrypt is a password-based key derivation function (like for example PBKDF2). Scrypt was designed to be "memory-hard" algorithm in order to make it expensive to perform large scale custom hardware attacks. It can be used for: * deriving cryptographic...

After looking around for a simple way to send encrypted email to Outlook, Mozilla and Netscape email clients, the modules had requirements that required installing and/or compiling other software. This module is a simple and secure method of sending ...

Crypt::OpenSSL::Guess provides helpers to guess OpenSSL include path on any platforms. Often MacOS's homebrew OpenSSL cause a problem on installation due to include path is not added. Some CPAN module provides to modify include path with configure-ar...

Given a CA certificate and another untrusted certificate, will show whether the CA signs the certificate. This is a useful thing to have if you're signing with X509 certificates, but outside of SSL. A specific example is where you're working with XML...
