SHA-512 Hash Generator

Generate the SHA-512 hash of any text or file. The 512-bit digest is computed locally in your browser and updates on every keystroke. Switch to File mode to fingerprint downloads and verify checksums without uploading anything.

About SHA-512

SHA-512 is a member of the SHA-2 family, published by NIST in FIPS 180-4. SHA-512 uses 64-bit words and 80 rounds to produce a 512-bit digest, the largest in the core SHA-2 family. The same input always yields the same digest, and a one-character change produces a completely different value.

Features

  • Text or file input (text, hex bytes, Base64, or Latin-1), up to 200 MB
  • Hex, uppercase HEX, or Base64 output
  • Hash each line for bulk processing of lists
  • Compare with a known hash to verify integrity instantly

Security

SHA-2 is the current workhorse for cryptographic hashing: TLS certificates, software signatures, blockchain systems, and file integrity all rely on it. For password storage, use a slow algorithm such as bcrypt (see the WordPress Password Hash Generator); for keyed message authentication, use the HMAC Generator. To see the whole family side by side, try the SHA2 Hash Generator, and for the newer sponge design see SHA3-256.

Frequently Asked Questions

SHA-512 produces 512 bits, shown here as 128 hexadecimal characters. You can also switch the output to uppercase or Base64.

Yes. The SHA-2 family has no known practical collision or preimage attacks and is recommended by NIST for digital signatures, certificates, and integrity checks.

On 64-bit processors SHA-512 is often faster because it works with 64-bit words, even though it produces a larger digest. On 32-bit systems SHA-256 is usually quicker.

Switch to File mode, drop the file in, and paste the published checksum into the compare box. A green message confirms the file matches. The file never leaves your browser.
