About SHA-512
SHA-512 is part of the SHA-2 family and produces a 512-bit hash value. It offers the highest security level among SHA-2 variants and is recommended for applications requiring maximum cryptographic strength and future-proofing against advances in computing power.
- Double the output size of SHA-256 for enhanced security
- Collision resistance: 2^256 operations required
- Preimage resistance: 2^512 operations required
- Used in DNSSEC, TLS, SSH, and high-security applications
- Better performance on 64-bit processors than SHA-256
