How to Use the SHA-512 Hash Generator
Type or paste any text into the input box — the SHA-512 hash is computed live using your browser's built-in Web Crypto API (crypto.subtle.digest). SHA-512 produces a fixed 512-bit (128 hex character) digest, twice as long as SHA-256, and is part of the same SHA-2 family standardized by NIST. Click Copy to grab the resulting hex digest.
Example
Hashing the text hello produces 9b71d224bd62f3785d96d46ad3ea3d73319bfbc2890caadae2dff72519673ca72323c3d99ba5c11d7c7acc6e14b8c5da0c4663475c2e5c3adef46f73bcdec043.
Common Use Cases
- Verifying file integrity against a published SHA-512 checksum.
- Generating high-entropy deterministic identifiers where a longer digest is preferred.
- Learning how longer-digest cryptographic hash functions behave with different inputs.
FAQs
- How is SHA-512 different from SHA-256? Both belong to the SHA-2 family and use a similar design, but SHA-512 operates on 64-bit words instead of 32-bit words and produces a 512-bit (128 hex character) digest instead of a 256-bit (64 hex character) one. On 64-bit hardware, SHA-512 can actually run faster than SHA-256 despite the longer output.
- Is SHA-512 secure for passwords? No — like SHA-256, SHA-512 is designed to be fast, which makes it a poor fit for password storage on its own. Use a slow, salted algorithm such as bcrypt or Argon2 for passwords instead.
- Is my text uploaded anywhere? No — hashing happens entirely client-side using the browser's native Web Crypto API. Nothing you type is sent to a server.
