CryptographyDecrypt(String, String, String) Method

public static Task<string> Decrypt(
	string cipherText,
	string key,
	string providerName
)

Parameters

cipherText  String

The encrypted text to decrypt.

key  String

The key to decrypt the ciphertext.

providerName  String

The type name of any symmetric cryptography provider derived from SymmetricAlgorithm that will perform the decryption.

Return Value

The default decryption algorithm is DES. Any other class derived from SymmetricAlgorithm can be used instead.
