Any transmitter wishing to send a message to a particular receiver enciphers the message with the PK and sends the ciphertext over an insecure channel; only the intended receiver, who has exclusive knowledge of
In cryptography, a key is a string of characters used within an encryption algorithm 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,...
Symmetric key cryptography makes use of two types of ciphers: block ciphers and stream ciphers. A block cipher takes a predetermined number of bits, known as a block, in the plaintext message and encrypts that block. Blocks are commonly composed of 64 bits but can be larger or smaller depe...

In cryptography, an encryption key is a variable value that is applied using analgorithmto a string or block of unencrypted text to produce encrypted text or to decrypt encrypted text. The length of the key is a factor in considering how difficult it will be to decrypt the text in a given...
Cryptography The process of concealing or coding information so that only the intended recipient can read it is known as cryptography. Cryptography has been used to encode messages for thousands of years and is still used in bank cards, computer passwords, and e-commerce. ...
in ciphertext; every instance of the letter B in plaintext would be changed to the letter E in the ciphertext, and so on. Using this key, which has an algorithm of "shift the letters forward by three," the word "help" in plaintext would be encrypted to be "khos" as ciphertext. ...
Because an attacker can obtain the public keys of people communicating, public key cryptography can always be analyzed with respect to chosenplaintext attacks. That is, an attacker can pick whatever plaintext they want, and encrypt it using the intercepted public key to perform analysis on the ...
