SHA-512 Hash Generator
Generate a SHA-512 hash of any text in hex or Base64. Free and private: runs in your browser.
Type or paste text to get its 512-bit SHA-512 digest.
Hashing runs locally in your browser. Your input never leaves this page.
Use cases
- Verify a download or file checksum.
- Create test fixtures for authentication code.
- Debug a hash mismatch between two systems.
Frequently asked questions
Is SHA-512 more secure than SHA-256?
Both are secure today. SHA-512 has a longer output and can be faster on 64-bit CPUs; SHA-256 is more widely used.
Is the SHA-512 Hash Generator free?
Yes. It is free with no sign-up, and it runs entirely in your browser, so your input is never uploaded or stored.
Is hashing the same as encryption?
No. A hash is one-way: you cannot get the input back. Encryption is reversible with a key. Use slow password hashes (bcrypt, Argon2, PBKDF2) for passwords and fast hashes (SHA-256) for integrity checks.
