Basic Cryptography Classical Cryptography Public Key Cryptography Overview 2. asymmetric key cryptography: asymmetric key cryptography, also known as public key cryptography, uses a pair of keys a public key and a private key to encrypt and decrypt data. the public key is available to anyone, while the private key is kept secret by the owner. hash functions: a hash function is a mathematical algorithm that converts data of any size into a fixed size output. hash. Public key cryptography could, theoretically, also be used to encrypt messages although this is rarely done because secret key cryptography algorithms can generally be executed up to 1000 times faster than public key cryptography algorithms.

Classical cryptography sender, receiver share common key keys may be the same, or trivial to derive from one another sometimes called symmetric cryptography two basic types transposition ciphers substitution ciphers. Asymmetric cryptography , also known as public key cryptography, refers to a cryptographic algorithm which requires two separate keys, one of which is private and one of which is public. Each key pair consists of a public key and a corresponding private key. [1][2] key pairs are generated with cryptographic algorithms based on mathematical problems termed one way functions. security of public key cryptography depends on keeping the private key secret; the public key can be openly distributed without compromising security. [3].
