About
Computes SHA-1, SHA-256, and SHA-512 locally. Input never leaves the browser.
How to use
Enter text, then generate a digest. Match the algorithm when you compare file hashes.
What this tool does
Computes SHA-family digests of text so you can see whether content changed.
Safety and privacy
Local compute. Do not store passwords as a raw SHA digest; that needs a dedicated password hash.
Limits
For text strings. Hash large binaries with a local tool such as sha256sum.
FAQ
Can a hash be reversed?
No. A hash is a one-way digest.
Which algorithm should I use?
Prefer SHA-256 or SHA-512 for new work. SHA-1 is for legacy compatibility.
Is it uploaded?
No.
