digest" of the input string. It is conjectured that it is computationally infeasible to produce two messages having the same message digest, or to produce any message having a given prespecified target message digest. The MD5 algorithm is intended for digital signature applications, where a large file must be "compressed" in a secure manner before being encrypted with a private (secret) key under a public-key cryptosystem such as RSA. In essence,

The MD5 Com Component creates an RFC1321 compliant MD5 string from a string of text or file content, The MD5 algorithm takes as input a string of arbitrary length and produces as output a 128-bit "fingerprint" or "message digest" of the input string. It is conjectured that it is computationally infeasible to produce two messages having the same message digest, or to produce any message having a given prespecified target message digest.

Directory compare & integrity check tool. Unlike most directory compare tools, it is intended for use in cases, when two directories can not be directly compared. Main features: compare directories on computers that are not connected, compare the same directory over time, very short digests that in most cases fit a floppy even for large directories

Fsum Frontend is a free and easy-to-use tool that allows to compute message digests, checksums and HMACs for files and text strings. It supports drag-and-drop and you can handle multiple files at once. The checksum generated can be used to verify the integrity of the files. It supports 58 algorithms: crc32, md5, sha, ...
