Module cipher 

The vault cipher half of a rotation.

rotate_cipher_password vets the cipher the server returned and builds the write that replaces its password. Decryption, password history and encryption are the vault’s ([Cipher::change_login_password]). cipher_has_password tells whether a cipher already holds a given password, so an ambiguous write outcome can be settled.
