SHA-1 ('''S'''ecure '''H'''ash '''A'''lgorithm) is a cryptographic hash function that was first published in 1995 in FIPS PUB 180-1 by the NSA as a fix to a flaw found in SHA-0.

In February of 2005 an attack was announced that could find collusions in SHA-1 requiring fewer than 2<sup>69</sup> operations.
