sha512
Hash the input data with SHA-512, according to NIST.FIPS.180-4
Precompile address
0x0100000000000000000000000000000000000101
Warning: SHA-512 vs SHA-512/256 Length-Extension Attacks
SHA-512 is vulnerable to length-extension attacks, which are relevant if you are computing the hash of a secret message. The SHA-512/256 variant is not vulnerable to length-extension attacks.
