Did you know?
In cryptography, a key is a string of characters used within an encryptionalgorithm for altering data so that it appears random. Like a physical key, it locks (encrypts) data so that only someone with the right key can unlock (decrypt) it. The original data is known as the plaintext, and the data after the key encrypts it is … See more Before the advent of computers, ciphertext was often created by simply replacing one letter with another letter in the plaintext, a method known as a "substitution cipher." For instance, suppose that someone sends a message … See more Although the above examples of early cryptography illustrate how using a random string of information to turn plaintext into ciphertext works, cryptographic keys … See more There are two kinds of encryption: symmetric encryption and asymmetric encryption, also known as public key encryption.
