+## Clamp Credentials

+

+Credentials should be specified in `src/main/resources/clds/clds-users.json`. You might specify you own credential file by redefining the `clamp.config.files.cldsUsers` in `application.properties`.

+

+Passwords should be hashed using md5, then using Bcrypt :

+```

+# pip3 install bcrypt  # if you don't have the bcrypt python lib installed, should be done once.

+# python3 -c 'import bcrypt; import hashlib; m = hashlib.md5(); m.update("password".encode()); m.hexdigest(); print(bcrypt.hashpw(m.hexdigest().encode(), bcrypt.gensalt(rounds=10, prefix=b"2a")))'

+```

+

+Default credentials are admin/password and cs0008/password.
