Starting with the origins of cryptography, it moves on to explain cryptosystems, various traditional and modern ciphers, public key encryption, data integration, message authentication, digital signatures …

Cryptography uses mathematical techniques to protect the security of information.

cryptography includes both high level recipes and low level interfaces to common cryptographic algorithms such as symmetric ciphers, message digests, and key derivation functions.

History of cryptography Cryptography, the use of codes and ciphers, began thousands of years ago. [1] Until recent decades, it has been the story of what might be called classical cryptography — that is, …

Cryptography (or cryptology) – practice and study of hiding information. Modern cryptography intersects the disciplines of mathematics, computer science, and engineering.

Cryptography is the practice of developing and using coded algorithms to protect and obscure transmitted information so that it may only be read by those with the permission and ability to decrypt it.
