What is SHA-512 Hash Generator for Text and Files?

The SHA-512 Hash Generator produces the 512-bit SHA-2 digest of any text or file, displayed as a 128-character hex string and in Base64. SHA-512 is used for file integrity verification, password-hashing schemes and digital signatures, and is often faster than SHA-256 on 64-bit processors. All hashing runs through the browser’s native Web Crypto API on your device.

Frequently asked questions

What is the difference between SHA-256 and SHA-512?

Both are SHA-2 hashes. SHA-512 produces a longer 512-bit digest and is often faster on 64-bit CPUs; SHA-256 is more widely used in certificates and blockchains.

Can SHA-512 be reversed?

No. Hash functions are one-way; the only way to find the input is to guess it.

Is it safe to hash confidential files here?

Yes. Files are hashed on your device and are not transmitted.
