  2. md5sum - Wikipedia

    en.wikipedia.org/wiki/Md5sum

    md5sum is a computer program that calculates and verifies 128-bit MD5 hashes, as described in RFC 1321. The MD5 hash functions as a compact digital fingerprint of a file. As with all such hashing algorithms, there is theoretically an unlimited number of files that will have any given MD5 hash. However, it is very unlikely that any two non ...

    en.wikipedia.org/wiki/MD5

    MD5 is prone to length extension attacks. The MD5 message-digest algorithm is a widely used hash function producing a 128- bit hash value. MD5 was designed by Ronald Rivest in 1991 to replace an earlier hash function MD4, [ 3] and was specified in 1992 as RFC 1321. MD5 can be used as a checksum to verify data integrity against unintentional ...

    Message authentication code. In cryptography, a message authentication code ( MAC ), sometimes known as an authentication tag, is a short piece of information used for authenticating and integrity -checking a message. In other words, to confirm that the message came from the stated sender (its authenticity) and has not been changed (its integrity).

    VHF Data Link. The VHF Data Link or VHF Digital Link ( VDL) is a means of sending information between aircraft and ground stations (and in the case of VDL Mode 4, other aircraft). Aeronautical VHF data links use the band 117.975–137 MHz assigned by the International Telecommunication Union to Aeronautical mobile (R) service.
