SHA-512 Hash Generator

Generate SHA-512 hashes of text or files locally. SHA-512 is the long-output member of the SHA-2 family, widely used for file checksums (Linux ISOs), package integrity and HMAC-SHA512.

Type or paste text to get its SHA-512 hash instantly, or drop a file of any size to hash it in chunks on your device. Choose hex or Base64 output, and paste an expected checksum to verify a match. SHA-512 gives a 512-bit digest and is fast on 64-bit CPUs.

512-bit digest · 128 hex characters · text is hashed as UTF-8

A hash is one-way: it can't be “decrypted”. Sites that claim to reverse SHA-512 only look the hash up in tables of previously hashed common strings. For passwords, use a slow hash like bcrypt or Argon2 — never plain SHA-512.

About SHA-512

SHA-512 produces a 512-bit (128 hex character) digest. On 64-bit processors it's often faster than SHA-256, and its larger output gives extra margin against future attacks.

It's used for Linux distribution checksums, npm and Subresource Integrity hashes (sha512-…), and as the basis of SHA-512/256, which this tool can also compute.

Hashing isn't encryption

A hash function turns any input into a fixed-size fingerprint. The same input always gives the same hash, the smallest change gives a completely different one, and there's no key to reverse it — which is why “hash decrypters” only look up precomputed hashes of common strings.

Hash text for checksums, deduplication and signatures; store passwords with a slow, salted algorithm like bcrypt instead. Verify downloads with the File Hash Checker.

Frequently Asked Questions

SHA-256 or SHA-512?

Both are secure. Use whatever the system you're matching expects; SHA-512 is slightly faster on 64-bit machines and gives a longer digest.

Can a hash be decrypted?

No. Hashes are one-way. Sites that “decrypt” hashes just search tables of hashes of common words and leaked passwords, which is why short or common inputs can be found and long random ones can't.

Is my data sent to your server?

No. This tool runs entirely in your browser using the Web Crypto API and JavaScript. Nothing you type or generate is uploaded, logged or stored.
