WebNov 9, 2015 · Cryptographic hash functions play a major role on Public Key Cryptography, but in this article, we will examine their use in computing/verifying checksums. Use of Cryptographic Hashes as Checksums Downloading a File on the Internet Many websites offering downloads provide the cryptographic hashes along with the downloadable files. An important application of secure hashes is the verification of message integrity. Comparing message digests (hash digests over the message) calculated before, and after, transmission can determine whether any changes have been made to the message or file. MD5, SHA-1, or SHA-2 hash digests are sometimes published on websites or forums to allow verification of integrity for downloaded files, including files retrieved using file sharing such as mir…
