Free hash generator for SHA-256 and SHA-512
A hash generator turns any text into a fixed-length fingerprint. Two matching hashes mean the text matches, without sending secrets to a server.
Paste your string and copy SHA-256 or SHA-512 in one click. Useful for checksums, config checks, and learning how digests work.
Everything runs in your browser. Nothing is uploaded. Use this hash generator when you need a quick digest for text, not for storing passwords.
Good for
- Text checksums
- Config checks
- Teaching digests
- Quick comparisons
Tips
- Pick SHA-256 by default
- Copy the full hash string
- Do not hash real passwords here
- Compare hashes, not plain text
Common questions
What is a hash generator?
It turns text into a short fingerprint called a hash. The same text always gives the same hash. You cannot reverse a hash back into the original text.
Which hash should I pick in this hash generator?
SHA-256 is the usual choice for file checks and configs. SHA-512 gives a longer fingerprint when your tool asks for it.
Is this hash generator free and private?
Yes. It runs in your browser with the Web Crypto API. Your text never leaves your device.
Can a hash generator encrypt my password?
No. Hashing is not encryption. It helps you compare two strings or check that text has not changed.
Does this hash generator support MD5?
No. This tool offers SHA-256 and SHA-512 only. Both are common and safer than MD5 for new work.
