This is the method that you
use to create an SHA-512 hash of a given file.
This is ideal for checking
if a file has been modified at some point or for verifying files.
SHA-512 offers a higher
level of confidence than the MD5-128 implementation that is also in
Cryptocx especially for verifying large files. We still recommend MD5 for
password verification in databases as it is easily secure enough for that.
Neither MD5-128 or SHA-512
have been shown to have any flaws at all.
