In croc, code phrase is 16 random bits that are menemonic encoded. This code phrase is hashed using sha256 and sent to a relay which maps that key to that connection. When the relay finds a matching key for both the receiver and the sender (i.e. they both have the same code phrase), then the sender transmits the encrypted metadata to the receiver through the relay. Then the receiver decrypts and reviews the metadata (file name, size), and chooses whether to consent to the transfer.
