Ola These libs are for encryption Download Things to note... DO NOT USE MD5, SHA1 for your secure applications e.g. ditigal signatures YOU CAN USE SHA-2 i.e. SHA256, SHA512 ANY HASH IS CRACKABLE, (EASIER FOR MD5 and SHA1) AND MORE HARDER IF IT HAS A "SALT" THE MOST ADVANCED ENCRYPTION IS BCRYPT. What is a CHF? A cryptographic hash function (CHF) is a hash function that is suitable for use in cryptography. It is a mathematical algorithm that maps data of arbitrary size (often...
