Generate text hashes locally
Create common message digests from pasted text and copy the result as hex, Base64, or Base64URL. This is handy for checksums, test fixtures, cache keys, and comparing digest output during development.
Hashing is not encryption
Hashes are one-way digests for comparison and verification. They do not hide secret data, and MD5 or SHA-1 should only be used for legacy compatibility checks, not new security-sensitive work.
