| - | https:// | + | SHA256 and SHA512 are both cryptographic hash algorithms. They are used for detecting whether data had been modified. The digest size SHA256 and SHA512 are 256 bit and 512 bit respectively. SHA512 is more resistant to attacks compared to SHA256. However, interestingly enough, under x86-64 architecture, |

| + | Below are the performance metrics from some of the machines I have. If you are not on x86-64, it is faster to use SHA256. | ||
