Examples of penny.recmd5.MD5State

penny.recmd5.MD5State
wmacinta.com/myjava/fast_md5.php for more information on this file.
Contains internal state of the MD5MessageDigest and the final state of the MD5MessageDigest. Also holds the final string of the MD5 hash for convienence.
"It is my hope that this library will be useful to programmers calculating md5s for input from ranged protocols such as http and ftp." - John Mercier @author Santeri Paavolainen @author Timothy W Macinta (twm@alum.mit.edu) (optimizations and bug fixes) @author John Mercier
