This document gives references for a collection of cryptographic algorithms. Each algorithm is assigned a standard ASCII name, and zero or more aliases. The intention is for each algorithm to be specified in sufficient detail that independent implementations will be able to interoperate.
The list has been designed initially for use by the Java Cryptography Architecture, but should be useful in any situation where a convention is needed for referring to algorithms by a string. It can also serve as a source of references for definitions and cryptanalysis of various algorithms. The intention is to develop API mappings for languages other than Java in future (probably based on existing cryptography libraries).
These documents use the terms "MUST", "SHOULD", and "MAY", and their negated forms, as defined in RFC 2119. These terms apply to crypto algorithm and library implementations that are intended to conform to some subset of SCAN.
In addition, the terms "WILL" and "WILL NOT" specify consistency requirements and policies for SCAN itself. If it is stated that something WILL be true, but it is not actually true, please report it as an error. New SCAN entries or changes to existing entries must satisfy all WILL and WILL NOT constraints.
The term "byte" always refers to an 8-bit byte, or octet. The value of a byte is an integer between 0 and 255 inclusive.
In algorithm descriptions,
The accompanying SCAN Conventions document includes other important information on the conventions used in compiling this list, which you should read before relying on it for any significant application. Also see these suggestions for cryptosystem designers.
The following are very useful resources for a wide range of algorithms:
Mac(Message Authentication Codes)
PRF(Pseudo Random Functions) *
* Experimental; not in JCE 1.2.
