1 ciphertext
Data that has been encrypted.نص مشفّر -
2 decryption
The process of converting encrypted content back into its original form to make it readable again. This is also called converting ciphertext back to plaintext. -
3 encryption
The process of converting readable data (plaintext) into a coded form (ciphertext) to prevent it from being read by an unauthorized party. -
4 encrypted data
Data that has been converted from plaintext into ciphertext. Encrypted messages are used to disguise the content of a message when it is sent or stored. -
5 public key algorithm
"An asymmetric cipher that uses two keys, one for encryption, the public key, and the other for decryption, the private key. As implied by the key names, the public key used to encode plaintext can be made available to anyone. However, the private key must remain secret. Only the private key can decrypt the ciphertext. The public key algorithm used in this process is slow (on the order of 1,000 times slower than symmetric algorithms), and is typically used to encrypt session keys or digitally sign a message." -
6 data encryption
The process of converting readable data (plaintext) into a coded form (ciphertext) to prevent it from being read by an unauthorized party.
