/*
* This is an OpenSSL-compatible implementation of the RSA Data Security,
* Inc. MD5 Message-Digest Algorithm (RFC 1321).
*
* Written by Solar Designer <solar at openwall.com> in 2001, and placed
* in the public domain. There's absolutely no warranty.
*
* This differs from Colin Plumb's older public domain implementation in
* that no 32-bit integer data type is required, there's no compile-time
* endianness configuration, and the function prototypes match OpenSSL's.
* The primary goals are portability and ease of use.
*
* This implementation is meant to be fast, but not as fast as possible.
* Some known optimizations are not included to reduce source code size
* and avoid compile-time configuration.
