What is SHA-512?
SHA-512 (Secure Hash Algorithm 512-bit) produces a fixed 128-character hexadecimal hash from any text input. It runs entirely in your browser using the Web Crypto API (SubtleCrypto) — your data never leaves your device.
Common uses
- High-security hashing — stronger collision resistance than SHA-256.
- Cryptographic applications — digital signatures, blockchain, certificate authorities.
- Password hashing (with salt) — the longer output makes it more resistant to brute-force.
- File verification — checksum large files where extra security matters.
Quick tips
- SHA-512 is more secure than SHA-256 but produces longer hashes (128 vs 64 characters).
- SHA-512 is faster on 64-bit systems than SHA-256 in many implementations.
- A SHA-512 hash is always 128 hexadecimal characters long, regardless of input size.
