Generates true random passwords by using the /dev/random feature of Linux, with the emphasis on security over pronounceability. It can also encrypt plaintext passwords given on the command line.

Massh makes it possible to perform the following on hundreds, or even thousands of hosts in a parallelized fashion: * Run Remote Commands * Push and Execute Pre-Written Scripts * Push Files * Pull Files

Super is a setuid-root program that offers: o restricted setuid-root access to executables, adjustable on a per-program and per-user basis; o a relatively secure environment for scripts, so that well-written scripts can be run as root (or some other uid/gid), without unduly compromising security. The design philosophy behind super is two-fold: (a) some users can be trusted when executing certain commands; (b) there are some commands, such as a script to mount CDROM's, which you'd like to be safely executable even by users who are NOT trusted. Although setuid-root scripts are insecure, a good setuid-root wrapper around a sensible non-setuid script can be hard to break, and super provides that wrapper so that even a non-trusted user can use the scripts.

This package provides an objective wrapper for OpenSSL Crypto Library

Nettle is a cryptographic library that is designed to fit easily in more or less any context: In crypto toolkits for object-oriented languages (C++, Python, Pike, ...), in applications like LSH or GNUPG, or even in kernel space.

py-bcrypt is a Python wrapper of OpenBSDs Blowfish password hashing code, as described in A Future-Adaptable Password Scheme by Niels Provos and David Mazieres.

This library implements Blowfish, DES, and Triple-DES.

[ excerpt from developer's www site ] The Cryptokit library for Objective Caml provides a variety of cryptographic primitives that can be used to implement cryptographic protocols in security-sensitive applications. The primitives provided include: Symmetric-key cryptography: AES, DES, Triple-DES, ARCfour, in ECB, CBC, CFB and OFB modes. Public-key cryptography: RSA encryption and signature; Diffie-Hellman key agreement. Hash functions and MACs: SHA-1, MD5, and MACs based on AES and DES. Random number generation. Encodings and compression: base 64, hexadecimal, Zlib compression. Additional ciphers and hashes can easily be used in conjunction with the library. In particular, basic mechanisms such as chaining modes, output buffering, and padding are provided by generic classes that can easily be composed with user-provided ciphers. More generally, the library promotes a "Lego"-like style of constructing and composing transformations over character streams.
