Frequently asked questions
Which hash algorithms are available?
Choose SHA-1, SHA-256, or SHA-512 through Web Crypto.
Is MD5 available?
No. MD5 is not secure for modern cryptographic use and is not offered.
Can a hash be reversed?
Cryptographic hashes are designed to be one-way, but short or common inputs may be guessed by lookup.
Is my input sent anywhere?
No. The digest is calculated by the browser and not uploaded.
Does changing one character change the result?
Yes. A small input change produces a substantially different digest.
