About this hash generator
Use this hash generator to create MD5, SHA-1, or SHA-256 digests from local text input for checksums, examples, and debugging.
Common use cases
- Create checksums for small text samples.
- Compare expected hash values while testing.
- Generate example digests for documentation.
How to use this tool
- Paste the text you want to hash.
- Select MD5, SHA-1, or SHA-256.
- Generate and copy the digest for comparison or documentation.
Example
Input
Dev Atlas
Output
SHA-256: 64-character hexadecimal digest
Common errors
- Changing even one character changes the hash digest.
- MD5 and SHA-1 are kept for compatibility checks and are not recommended for new security uses.
- Hashing is one-way, so the original text cannot be recovered from the digest.

FAQ
Are hashes reversible?
No. Hashes are one-way digests, but weak inputs can still be guessed.
Should I use MD5 for security?
No. MD5 is included for compatibility checks, not modern security.
Does hashing run locally?
Yes. SHA hashes use the browser Web Crypto API, and MD5 runs in the browser.
