SHA 1-2-3

NIST is currently in the final stages of defining a new "secure hashing algorithm" (SHA) [1]. The goal of the competition is to find a replacement for the current standard ("SHA-2", aka SHA-256 and SHA-512). NIST attempts to be somewhat proactive in defining crypto standards, realizing that new standards need to be implemented well before the old once are considered broken.

The three popular hash functions, MD5, SHA1 and SHA2, all use variations of a particular hashing algorithm known as "Merkle-Damgård Construction". Attacks have been developed for MD5 and SHA1, and it is plausible that they will be extended to SHA2 in the future. As a result, the candidates for SHA-3 use different algorithms that are hopefully safe from similar attacks.
