- Cryptix Standard Cryptographic Algorithm Naming - Introduces a system to enumerate and give standard reference identifiers for cryptographic algorithms with sufficient detail that independent implementations will be able to interoperate.
- Cryptography: An Investigation of a New Algorithm vs. the RSA - Sarah Flannery's paper describing her Cayley-Purser algorithm.
- General Hash Function Algorithms - General hash function algorithm implementations for string hashing in the object pascal, c and c++ programming languages.
- Hash Generator - An online too from UtilitiesMan that can generate hashes for 35+ different hash algorithms.
- Kremlin by Mach 5 Software - A description of various cryptographic algorithms and a commercial suite of encryption software.
- MD5 Encryption - A online tool which encrypts a normal string into its equivalent md5 hash state. Also contains a database of encrypted strings to allow limited decryption.
- MD5 Hash Generator - An MD5 hash generator.
- MD5.My-Addr.com - Online MD5 database for decrypting hashes to strings and some basic tools for encoding.
- North American Cryptography Archives - A comprehensive archive for cryptography source code, software, literature, and links.
- Teutoburgo: OTP4U - Includes a Java crypto-tool that allows the users to easily exchange a random key between them and then use it as a key for a One Time Pad cipher.
