SHA-2 is a set of cryptographic hash functions which includes SHA-224, SHA-256, and SHA-512. The 256 in SHA-256 represents the bit size of the hash output or digest when the hash function is performed. Not all software supports every digest size within the SHA-2 family. This article focuses specifically on SHA-256 and its compatibility with various software platforms and operating systems. As a general rule, SHA-256 is supported on OS X 10.5+ and Windows XP SP3+.
