Difference between Cryptography and Cryptology Last Updated : 12 Jul, 2025 Comments Improve Suggest changes Like Article Like Report 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. Cryptography vs CryptologyWhat is Cryptography?Cryptography is the study of converting plain text(readable format) to ciphertext(non-readable format), also called encryption. Cryptography involves various algorithms and protocols to ensure data confidentiality, integrity, authentication, and non-repudiation. Cryptography has a wide range of uses nowadays, including secure web communication, online money management, and safe data storage. It is also used in military & government communications, and electronic voting systems. Cryptography is a key component of data security, and its advancement has been important in protecting sensitive data from unauthorized access. Cryptography and CryptologyWhat is Cryptology?Cryptology is the study of both cryptography (conversion of data from plain text to cipher text) and cryptanalysis (the determination of how to access the data without the necessary cryptographic key). Cryptology includes a broader scope than cryptography, including analyses of numerical frameworks, calculations, and hypothetical cryptographic perspectives.
