Frequently Asked Questions

What is SHA-512 hashing?
SHA-512 is a cryptographic function from the SHA-2 family that produces a 512-bit (128 hex character) digest — twice the output length of SHA-256.
What is the difference between SHA-512 and SHA-256?
SHA-512 produces a longer 512-bit digest, offers a higher security margin, and can be faster than SHA-256 on 64-bit hardware due to its internal design.
When should I use SHA-512 instead of SHA-256?
Use SHA-512 when maximum collision resistance is needed, such as in high-security digital signatures or when targeting 64-bit platforms where SHA-512 is natively faster.
Is a SHA-512 hash reversible?
No. Like all SHA-2 functions, SHA-512 is a one-way operation — the original input cannot be recovered from the hash.
What format does the SHA-512 output use?
The output is a 128-character lowercase hexadecimal string representing the 512-bit digest.
Does generating a SHA-512 hash require sending data to a server?
No. SHA-512 is computed entirely in your browser using the Web Crypto API — nothing leaves your device.
