serious cryptography a practical introduction to modern encryption

It is the science concerned with methods of data protection through encryption and related techniques. It protects information and communications using secret codes so that it can be read or understood by the intended recipient only. – The fundamental objective of cryptography is to provide confidentiality by encryption methods. It basically uses an algorithm to encrypt the data and a secret key to decrypt it. Encryption is a process of encoding a message using an algorithm and a key. Encryption is the principle application of cryptography makes data incomprehensible to ensure its confidentiality.

It is the study of concepts like encryption and decryption. It is the art of creating codes using the techniques of encryption and decryption. – Cryptography is the practice of securing information by transforming it into a secured format for transmission across insecure networks. The Enigma is one of the best examples of encryption of all time.ĭifference between Encryption and Cryptography Basics There are many types of algorithms used for encryption which involve different ways of encoding and decoding information. Encryption basically uses an algorithm to encrypt the data and a secret key to decrypt it. Depending on the method, the key can be a password, a secret number, or just a sequence of bits. Decryption requires a secret decryption key. So, encryption turns a plaintext into a ciphertext and decryption turns a ciphertext back into a plaintext. It is the process of translating a message (referred to as plaintext) into an encrypted message (referred to as ciphertext). Encryption is the practice of concealing data or information in such a way that it appears random and can be accessed by authorized parties only while unauthorized users cannot access it.

Encryption is the principle application of cryptography which makes data incomprehensible to ensure its confidentiality.
