It looks like each file is using SHA256 to encrypt the hash which is considered to be very strong. The checksum file contains all of the original hashes for the files listed below it. I have also put the full VC 2008 project that includes OpenSSL headers and its static library. Hash algorithms take an arbitrary amount of data and convert it into a manageable fixed-length representation of that data, like a signature for the original data. Next, click on a hashing algorithm (e.g., CRC, MD5, SHA1, SHA256, etc) to generate the hash checksum for the files. An obvious application would be to apply such an algorithm to a file (text or binary) as a means of determining whether or not it has been tampered with. Each version comes with two hash values: 160-bit SHA1 and 256-bit SHA256. Use FCIV to compute MD5 or SHA-1 cryptographic hash values.
