Calculate and validate checksums Checksum Validator allows you to validate and calculate checksums (either SHA-1 or MD5 digest methods) for files that you have downloaded (or will upload). Checksum Validator is for the Mac OS X and it is freeware!More sites are including either MD5 or SHA-1 checksums for their files. With this utility, you can verify that the file you download matches theirs; ensuring that there was not corruption of the data or tampering by anyone else. Checksum Validator can produce and validate either type of checksum.Of the two checksums MD5 is more common and it will be 32 characters long (written in hexadecimal notation, so that is 16 bytes or 128 bits), but SHA-1 is 40 characters long (20 bytes, 160 bits) and is considered a little more secure than MD5.For more information on checksums and the MD5 and SHA-1 digests head over to Wikipedia, they have many good articles explaining the details on message digests or the "official" term of, cryptographic hash functions, and articles on the MD5 and SHA hash functions.It is extremely easy to create and validate checksums with Checksum Validator: ?
