WebNov 17, 2009 · Whether the cryptographic weaknesses of MD5 matter or not depends on your application, where the files come from, and what an attacker could stand to gain if he tricked your program into thinking two different files were identical. MD5 is still a very good checksum, just not so great as a cryptographic hash. Share Improve this answer Follow WebFor MD5 the key length is 128 bits, for SHA-1 the key length is 160 bits, SHA-256 the key length is 256 bits. If a cryptographic weakness is discovered in the design of the hash algorithm, however, this weakness can reduce the effective key length of the hash function to be less than the intended design length.
