How to use Hash
Create local text hashes for checksums, fixtures, and quick comparisons. MD5 and SHA-1 are legacy checksum options, not password guidance.
- Paste or type your input.
- Load the sample if you want a quick check.
- Run the action, review the result, then copy only what you need.
Examples
Compare checksum
Input: Paste expected digest
Output: Match or does not match
Legacy MD5
Input: hello
Output: 5d41402abc4b2a76b9719d911017c592
Common use cases
Verify copied text
Generate a checksum for a small pasted value and compare it with an expected digest.
Create fixture IDs
Use UUID or ULID for identifiers instead of hashes when uniqueness is the goal.
Debug JSON examples
Format JSON before hashing if whitespace should be stable.
Limitations
Not password storage
This page does not salt, stretch, store, or recommend password hashes.
Large text guardrail
Very large pasted input is blocked to keep browser-local hashing responsive.
FAQ
Are MD5 and SHA-1 secure?
They are included for legacy checksum compatibility, not for cryptographic security or password storage.
Does hashing upload my text?
No. Hashing happens in the browser.
Can I compare an expected checksum?
Yes. Paste the expected digest in the compare field to see match status.
