Procedures based on a mathematical formula; used to encrypt data.
asymmetric cryptographic algorithm:
Encryption that uses two mathematical related keys.

A cipher that manipulates an entire block of plain text at one time.
A block cipher that operates on 64-bit blocks and can have a key length from 32 to 448 bits
Data that has been encrypted
Unencrypted data
The science of transforming information into a secure form while it is being transmitted or stored so that unauthorized persons cannot access it.
Data Encryption Standard(DES):
A symmetric block cipher that uses a 56-bit key and encrypts data in 64-bit blocks.
The process of changing ciphertext into plaintext
digital signature:
An electronic verification of the sender
elliptic curve cryptography (ECC):
An algorithm that uses elliptic curves instead of prime numbers to compute keys.
