how to discover the encryption/decryption algorithm used in data captured by wireshark

I have a local network program : client program and server program , the client program need some updating but the coder is not available , so we want to develop the client program ourselves , when we used wireshark program to know the communication way between the client and server program , we saw the login data we entered seems to be encrypted as attached , the login user was: 65479

and the password was: 12345@

and we saw the data in the attached file , we want to know the encryption/decryption algorithm used so we can communicate with the server by new program
