comparison dcrypt/crypto/hashes/MD5.d @ 28:ad687db713a4

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Further reworked the code for hash padding. Replaced all instances of 'char[]' with 'string' and removed a few 'const' modifiers as per Glenn Haecker's patch for D2 compatibility. Updated CONTRIBUTORS file.
