Class Hash512

java.lang.Object

net.i2p.data.SimpleDataStructure

net.i2p.crypto.Hash512

All Implemented Interfaces:

DataStructure

public class Hash512
extends SimpleDataStructure

SHA-512 secure hash algorithm implementation. This class provides the SHA-512 hash algorithm as specified in FIPS PUB 180-4, producing a 64-byte (512-bit) message digest. SHA-512 offers the highest security level in the SHA-2 family with excellent performance characteristics.

Common uses in I2P include:

• Maximum security requirements for sensitive operations
• Long-term cryptographic key derivation
• Digital signatures with strongest hash protection
• Integrity verification for critical system components
