Algorithms are considered secure

Cryptography is associated with the process of converting ordinary plain text into unintelligible text and vice versa. It is a method of storing and transmitting data in a particular form so that only those for whom it is intended can read and process it. Cryptography not only protects data from theft or alteration, but can also be used for user authentication.


Provides secure communication in the presence Phone Number List   of third parties. Encryption uses an algorithm and a key to transform an input (i.e., plaintext) into an encrypted output (i.e., ciphertext). A given algorithm will always transform the same plaintext into the same ciphertext if the same key is used. How does it work?  if an attacker cannot determine any properties of the plaintext or the key, given the ciphertext.




An attacker should not be able to determine anything about a key given a large number of plaintext/ciphertext combinations that used the key. In short: Cryptography is a method of protecting information and communications through the use of codes, so that only those for whom the information is intended can read and process it.
