Developers use hashes to compare whether two texts are identical, verify downloads, or learn how digests work. Storing or verifying user passwords with MD5 or bare SHA is obsolete and unsafe. Use bcrypt, scrypt, or Argon2 with a salt for credentials. This tool will not stop you from hashing a password, but the MD5 output reminds you it is for checksums only.
The input string is encoded as UTF-8 before hashing. SHA family digests use the Web Crypto API in the browser; MD5 uses a local implementation. Output is lowercase hexadecimal with no spaces.
No HMAC with a secret key, no hashing uploaded files as binary blobs, no bcrypt/Argon2, and no salt management. SHA-1 remains for legacy checksum scenarios, not new security designs.
That is the promise behind every tool here. Files are read in your browser tab, processed there, and discarded when you close it — never uploaded to our servers.
