About this tool
Hash Generator — A cryptographic hash maps input to a fixed-length digest. A tiny input change produces a different output, which is useful for integrity and comparison.
Hashing is one-way by design, but weak inputs can still be guessed. Password storage requires a dedicated slow, salted password-hashing function in trusted server code.
How to use it
- Choose an available algorithm.
- Paste the text and generate the digest.
- Compare the algorithm and exact text encoding before comparing hashes.
Example
FoundSchool
(digest depends on the selected algorithm)
Record the algorithm and encoding with a digest; the hash alone is not enough context.
Common uses
- Compare text or file metadata in a workflow.
- Create example digests for documentation.
- Learn how input changes affect a hash.
What to know
- A hash does not encrypt data and cannot prove who created it.
- Do not use a browser utility to store or process real passwords.

Frequently Asked Questions
Can I recover the original text from a hash?+
A proper cryptographic hash is not designed to be reversed, although predictable inputs can be guessed and tested.
Why do identical texts sometimes produce different hashes elsewhere?+
The algorithm, character encoding, line endings, normalization, or hidden whitespace may differ.
Should I hash passwords with this tool?+
No. Use a dedicated password-hashing function such as Argon2, scrypt, or bcrypt in your application.
