Decryption is the reversal of encryption, producing plaintext as a function of the cypher and the key.
A: Symmetric
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
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.
The flexibility of public key cryptography is in the fact that the key has two parts one is public and other is kept secret. That is encryption is done using public key while decryption is done using secret key. Thus message cannot be decrypted by unwanted person.
Encrypted files can only be accessed by authorized computer users who have the decryption key. Encryption is a popular technique in Information Security.
Symmetric-key algorithms are a class of algorithms for cryptography that use trivially related, often identical, cryptographic keys for both decryption and encryption.
