SHA-512 Hash Generator
Get the SHA-512 hash of text or a file in an instant. Type or paste text and the 512-bit hash, 128 hex characters long, updates as you type; files are hashed without being uploaded.
How to generate an SHA-512 hash
- 1Type or paste text, or switch to “A file” and choose one.
- 2Read the SHA-512 hash below.
- 3Copy it, in lowercase or uppercase.
What SHA-512 is for
SHA-512 is the larger member of the SHA-2 family. It's common in Linux distribution checksums and some signature schemes, and it often runs faster than SHA-256 on 64-bit processors.
Security
SHA-512 has no known practical attacks. Like all fast hashes, it isn't meant for storing passwords on its own.
Text or files
Hash text as you type, encoded as UTF-8, or choose a file up to 2 GB. Files are read in your browser and never uploaded, so it's safe for private documents.
Frequently asked questions
- Is anything sent to a server?
- No. Everything is computed in your browser and nothing leaves your device.
- What does an SHA-512 hash look like?
- 128 hex characters, starting with 9b71d224bd62f378 for the word “hello”.
- Can a hash be reversed?
- No. A hash is a one-way fingerprint; the only way back is guessing inputs until one matches, which is why short or common inputs are easy to look up.
