SHA-512 Generator

Runs in browser Security

Compute SHA-512 digests locally with WebCrypto, output as hex or Base64.

Privacy: This tool runs entirely in your browser. Your input never leaves your device.

What is a cryptographic hash?

A cryptographic hash turns any input into a fixed-size digest (32 bytes for SHA-256) such that the same input always gives the same digest, a one-character change gives a completely different one, and the input cannot be recovered from the output. Hashes verify file integrity, fingerprint content and underpin signatures and HMAC. SHA-256 and the SHA-2 family are current; MD5 and SHA-1 are broken against deliberate collisions and should only be used as checksums.

Security note: A plain hash is not a password store. Passwords need a slow, salted algorithm — Argon2id, scrypt or bcrypt — because SHA-256 and MD5 can be tried billions of times per second.

How to use SHA-512 Generator

  1. Paste the text.
  2. Choose the output format.
  3. Copy the 128-character digest.

ddaf35a193617abacc417349ae20413112e6fa4e89a97ea20a9eeee64b55d39a2192992a274fc1a836ba3c23a3feebbd454d4423643ce80e2a9ac94fa54ca49f

Frequently asked questions about SHA-512 Generator

Is SHA-512 more secure than SHA-256?

It offers a larger 512-bit digest and is often faster on 64-bit CPUs, but both are considered secure. SHA-256 is far more common; pick SHA-512 when a protocol or policy asks for it.

What is the output length?

512 bits: 128 hexadecimal characters or 88 Base64 characters.

Can I hash binary data?

This tool hashes the UTF-8 bytes of the text you paste. For files use a command-line tool such as sha512sum or certutil -hashfile.

Technical notes

SHA-512 operates on 64-bit words and 1024-bit blocks, producing a 512-bit digest. On 64-bit processors it is often faster than SHA-256 despite the larger output.
