A: Symmetric
Decryption is the reversal of encryption, producing plaintext as a function of the cypher and the key.
Encryption/decryption, Digital signature and Key exchange
Conventional encryption ciphers rely on a single key for both encryption and decryption. Modern protocols will use a private key for encryption and a different public key for decryption. These two keys are mathematically related in a fashion that allows them to encrypt/decrypt the same data successfully.
Using the same (or different) hardware will work with AES as long as the encryption and decryption use the same key. AES relies on the symmetric encryption key which means the same key is used to lock and unlock the data. The hardware that uses it does not matter.
Symmetric
RSA decryption using a public key involves the recipient using the public key provided by the sender to decrypt the encrypted message. The recipient uses the public key to raise the ciphertext to the power of the public exponent, and then takes the result modulo the public modulus to obtain the original plaintext message.
Public key decryption works by using a pair of keys - a public key and a private key. The public key is used to encrypt data, which can only be decrypted by the corresponding private key. This ensures secure communication over the internet because only the intended recipient, who possesses the private key, can decrypt the data. This method helps prevent unauthorized access to sensitive information during transmission.
Symmetric cryptography only requires one key for both encryption and decryption and therefore in some cases are a issue.
how to convert encryption to decryption using VB
decryption is the process of extracting the original information from the encrypted data.
Encrypted files can only be accessed by authorized computer users who have the decryption key. Encryption is a popular technique in Information Security.
