SHA1 vs md5 vs SHA256: which to use for a PHP ... The answers below are quite technical and illuminating, but they don't change the bottom line. MD5 is obsolete and should not be used in any new applications needing a cryptographic hash. This has been true for nearly 20 years, so long that the same thing can now be said about it's successor SHA1. If by "convenient" you are referring to the 128 ... An md5 is 128-bit, a sha1 is 160-bit. In the question this is reversed. A major difference between md5 and sha1 is that an example of a sha1 collision has yet to be found. I.e. if you use md5 for two different inputs, it's possible to get the same hash; with sha1 it's not. MD5 and SHA-1 have a lot in common; SHA-1 was clearly inspired on either MD5 or MD4, or both (SHA-1 is a patched version of SHA-0, which was published in 1993, while MD5 was described as a RFC in 1992). The main structural differences are the following: SHA-1 has a larger state: 160 bits vs 128 bits. SHA-1 has more rounds: 80 vs 64. It is well known that SHA1 is recommended more than MD5 for hashing since MD5 is practically broken as lot of collisions have been found. With the birthday attack, it is possible to get a collision in MD5 with 2 64 complexity and with 2 80 complexity in SHA1. It is known that there are algorithms that are able to crack both of these in far lesser time than it takes for a birthday attack.
