Frequently asked questions
Is my text uploaded to a server?
No. Hashes are computed with your browser's built-in crypto.subtle API, so your text never leaves this page — nothing is uploaded or stored anywhere.
Which hash algorithms are supported?
SHA-256, SHA-384 and SHA-512 — the full SHA-2 family. Input is encoded as UTF-8 before hashing.
Why are MD5 and SHA-1 not offered?
They are cryptographically broken and should no longer be used for integrity or security purposes, so this tool only offers the secure SHA-2 algorithms.
