How SHA-512 works
SHA-512 is a member of the SHA-2 family that takes input of any length and always produces a fixed 512-bit digest, usually shown as 128 hexadecimal characters.
The output is deterministic — the same input always yields the same hash — while a single changed bit produces a completely different digest (the avalanche effect).
SHA-512 is a strong, collision-resistant SHA-2 variant that produces a 512-bit digest, widely used for integrity and signatures.
Key features
- Compute SHA-512 from text or files
- Lowercase or uppercase hex output
- Instant, one-click hashing
- Deterministic results
- Runs 100% in your browser
- Files never leave your device
Privacy guarantee
All hashing is performed locally in your browser using the Web Crypto API. Your text and files are never uploaded, never stored, and never logged.
How to generate a hash
- 1
Enter text or choose a file
Type or paste your text, or switch to the File tab and drop a file.
- 2
Compute the hash
The SHA-512 digest is calculated instantly as you type or once the file is loaded.
- 3
Copy the digest
Copy the 128-character hex digest for integrity checks, verification, or storage.
Frequently asked questions
What is SHA-512 used for?
SHA-512 is used for file integrity, digital signatures, and password derivation where a strong 512-bit digest is required.
Can a hash be reversed?
No. Hash functions are one-way by design — you cannot recover the original input from the digest.
Does my file leave my device?
No. All computation happens locally in your browser.
