Generate the SHA-512 hash of any text instantly. SHA-512 is the 512-bit member of the SHA-2 family, producing a 128-character digest. It is used in TLS, code signing, file integrity and key derivation, and is stronger than MD5 and SHA-1.

Trusted & free

It is completely free, private and requires no signup.

Hashing is one-way

You cannot recover the original input from a hash.

Use salted KDFs for passwords

bcrypt or argon2 for passwords; SHA-256 for integrity.

Verify, don't rely on speed

Compare digests for integrity; prefer slow algorithms for secrets.

How it works

Enter any text, password or file content — the hash updates in real time.

Use the uppercase toggle and copy button to compare two files or strings.

Frequently Asked Questions

It offers a larger 512-bit output and is often faster on 64-bit CPUs, but both are cryptographically secure. Choose based on the system you integrate with.

No. It is far too fast. Use bcrypt, argon2 or PBKDF2 with many iterations for password storage.

No. Like all hashes it is one-way — you cannot recover the original input.
