Frequently asked questions about SHA-512 Generator

Is SHA-512 more secure than SHA-256?

It offers a larger 512-bit digest and is often faster on 64-bit CPUs, but both are considered secure. SHA-256 is far more common; pick SHA-512 when a protocol or policy asks for it.

What is the output length?

512 bits: 128 hexadecimal characters or 88 Base64 characters.

Can I hash binary data?

This tool hashes the UTF-8 bytes of the text you paste. For files use a command-line tool such as sha512sum or certutil -hashfile.

Technical notes

SHA-512 operates on 64-bit words and 1024-bit blocks, producing a 512-bit digest. On 64-bit processors it is often faster than SHA-256 despite the larger output.
