The file src/md5.cpp is derived from a public domain implementation. The original license text is as follows:

In case this attempt to disclaim copyright and place the software in the public domain is deemed null and void, then the software is Copyright © 2001 Alexander Peslyak and it is hereby released to the general public under the following terms:

There’s ABSOLUTELY NO WARRANTY, express or implied.

(This is a heavily cut-down “BSD license”.)

This differs from Colin Plumb’s older public domain implementation in that no exactly 32-bit integer data type is required (any 32-bit or wider unsigned integer data type will do), there’s no compile-time endianness configuration, and the function prototypes match OpenSSL’s. No code from Colin Plumb’s implementation has been reused; this comment merely compares the properties of the two independent implementations.

The primary goals of this implementation are portability and ease of use. It 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.
