Symmetric key cryptography Both the sender and the receiver share a single key. to encrypt plaintext and send the ciphertext to the receiver. On the other hand, the receiver applies the same key to decrypt the message and recover the plain text. Public key cryptography This is the most revolutionary concept of the last 300-400 years.


In public key cryptography, two Phone Number List   related keys (public and private key) are used. The public key can be distributed freely, while its paired private key remains secret. The public key is used for encryption and the private key is used for decryption. Hash functions No key is used in this algorithm. A fixed length hash value is calculated.




based on the plain text which makes it impossible to retrieve the content of the plain text. Many operating systems also use hash functions to encrypt passwords.
