Hashes cannot be decrypted and are not password storage.
Frequently asked questions
Can I turn a SHA-256 value back into its input?
No. It is a one-way hash, not encryption. Hex output has 64 characters. Spaces, line endings, and file bytes affect the value. Compare against a fingerprint from a trusted source.
Is my file or input sent to a server?
No. Processing stays in your current browser session.
