Difference between Cryptography and Cryptology
Cryptography is defined as the study of rules and regulations that protect data from unauthorized access and it is also the study of conversion of plain text to cipher text. On the other hand, Cryptology is the study of the conversion of plain text to ciphertext and vice versa. It is also called the study of encryption and decryption. One major difference between both is that Cryptology is the superset of Cryptography.
