bcrypt and Argon2 - the algorithms built for password storage, salted automatically.
This is a dev/testing tool. Don't paste a real production secret here - the text is sent to this server to compute the hash. For your own accounts, always hash server-side in your application code.
Type a password under Hash and click Hash to get both a bcrypt and an Argon2 hash at once. To check a password against an existing hash, paste both under Verify and click Verify - the algorithm is detected automatically from the hash's own prefix.
Argon2 is the more modern choice and generally recommended today; bcrypt remains widely supported and battle-tested. Both are included since either is a reasonable choice depending on what your stack already uses.
This is a dev/testing tool - don't paste a real production secret, since the text is sent to this server to compute the hash. Always hash server-side in your own application code for real accounts.
By its prefix - $2a$/$2b$/$2y$ for bcrypt, $argon2 for Argon2 - so you don't have to specify it yourself.
