Remarks

Digest algorithms are secure hashing algorithms that are used to generate unique fixed-length signatures for arbitrary data.

The most commonly used digest algorithms are currently MD5 and SHA-1, however, MD5 was successfully broken in 2008 and should be avoided. In late 2013, Microsoft announced that they would be retiring their use of SHA-1 in their products by 2016 with the assumption that its days as an unbroken digest algorithm were numbered. It is speculated that the SHA-1 digest algorithm will be vulnerable to collisions, and thus no longer considered secure, by 2018.

Microsoft and other vendors plan to move to the SHA-2 suite of digest algorithms which includes the following 4 variants: SHA-224, SHA-256, SHA-384, and SHA-512.
