SHA-512 Hash Generator

Calculate a SHA-512 hash of UTF-8 text locally with HEX, Base64 or Base64URL output. No input is sent to servers.

SHA-512 is a one-way cryptographic digest; it does not authenticate a sender and is not suitable for password storage by itself.

What is SHA-512 Hash Generator?

SHA-512 is a cryptographic hash function in the SHA-2 family that generates a 512-bit digest for any input. A hash can help compare data integrity, but unlike a MAC or digital signature it does not authenticate who created a message. Hashing is not encryption, and ordinary SHA-512 should not be used alone to store passwords; use purpose-built password hashing methods such as Argon2id.

How to use this tool

  1. Enter or paste the UTF-8 text you want to hash.
  2. Select HEX, Base64 or Base64URL representation, then compute the SHA-512 digest locally.
  3. Copy or download the result without sending your input across the network.

Example

SHA-512 of 'abc' begins ddaf35a193617aba and contains 128 hexadecimal digits.
