Asymmetric encryption uses two separate keys: a public key and a private key. Often a public key is used to encrypt the data while a private key is required to decrypt the data. The private key is only given to users with authorized access. As a result, asymmetric encryption can be more effective, but it is also more costly. 1. Basic Steps.

Encrypted data is commonly referred to as ciphertext, while unencrypted data is called plaintext. Currently, encryption is one of the most popular and effective data security ...The initialization vector to use for encryption or decryption. For MODE_CBC, MODE_CFB, and MODE_OFB it must be 16 bytes long. For MODE_OPENPGP mode only, it must be 16 bytes long for encryption and 18 bytes for decryption (in the latter case, it is actually the encrypted IV which was prefixed to the ciphertext).This method of encryption is known as public key cryptography. In asymmetric encryption, two keys are used: a public key and a private key. Separate keys are used for both the encryption and decryption processes: The public key, as the name suggests, is either publicly available or shared with authorized recipients.I need help using RSA encryption and decryption in Python.
