Frequently Asked Questions
Is my text sent to a server?
No. The hash is computed entirely in your browser using the Web Crypto API — nothing you type is ever transmitted anywhere.
SHA-256 vs SHA-512 — which should I use?
SHA-512 produces a longer (512-bit) digest and is often faster on 64-bit hardware. SHA-256 is more common in practice (Git, TLS certificates) simply due to convention — both are considered cryptographically secure today.
Can I reverse a SHA-512 hash back to the original text?
No — SHA-512 is a one-way function by design. There is no way to recover the original input from the hash alone.
