SHA-512 Generator
Developer ToolsGenerate a SHA-512 hash of any text or file, with a checksum comparison built in.
Runs entirely in your browser — nothing is uploaded
Features
- SHA-512 digests of text or of a file, computed in your browser.
- Every other algorithm shown alongside for comparison.
- Verify against a published checksum without reading hex by eye.
- Hex or Base64, upper or lower case.
- Files are never uploaded.
How to use the SHA-512 Generator
- 1Paste your text, or drop a file in to checksum it.
- 2Copy the SHA-512 digest, or paste the published one to compare.
- 3Switch algorithms if the publisher used a different one.
Frequently asked questions
Is SHA-512 more secure than SHA-256?
Both are considered secure and neither has a practical attack. SHA-512 has a longer digest and is actually faster on 64-bit hardware because it works on 64-bit words, but SHA-256 remains the more common choice and is entirely sufficient.
Why is my digest different from another tool?
Almost always a difference in the input rather than the algorithm — a trailing newline, different line endings, or the file being saved in a different encoding. A single byte changes the whole digest, which is exactly what makes it useful.
What is SHA-512 used for?
File integrity, digital signatures, and as the underlying hash in HMAC for signing API requests and webhooks. It is also the basis of the sha512-crypt password format used by some Linux distributions, though a purpose-built password hash is a better choice today.
