This program is useful to understand the OpenSSL APIs calls and their usage into the program. The checksum file contains all of the original hashes for the files listed below it. Otherwise, you will get compilation error like as "undefined reference to `SHA1_Init'" etc. The provided methods can create hash digest, signatures with private keys and HMAC (hashed message authentication code. NOTE: When you execute the hash command, you will see a number in the screen. Takes an input file, calculates the hash out of it, then encodes the hash and signs the hash. This launches the HashTools program and adds the selected file(s) to the list. Use this service only when your input file is an encoded hash.
