hash - Is double SHA-256 the best choice for Bitcoin

SHA-256 is a member of the SHA-2 cryptographic hash functions designed by the NSA. SHA stands for Secure Hash Algorithm. Cryptographic hash functions are mathematical operations run on digital data; by comparing the computed "hash" (the output from execution of the algorithm) to a known and expected hash value, a person can determine the datas integrity.

This program can generate two variants: SHA256 and Bitcoin Bitcoin uses two rounds of SHA256, feeding the result of the first round into the message part of the second round. First test were done with two separate rounds, one for each round of SHA256 of Bitcoin. All the example are based on the example, which is mentioned on a bitcoin Wiki:
