Asymmetric Encryption – Public Key Encryption

Asymmetric Encryption also known as public key encryption is a type of encryption that uses two different keys for encryption and decryption. One key to encrypt the plaintext, and one key to decrypt the cyphertext. The encryption key(Public Key) is published so that anyone can encrypt a message. The decryption key(Private Key) is kept private, …


Popular Symmetric Encryption Algorithms

Both sides, the sender and the receiver must know the secret key so they can encrypt and decrypt the information. Symmetric algorithms can be divided into stream algorithms and block algorithms. …
