CryptographyDecryptAsync(String, String, SymmetricAlgorithm) Method

public static Task<string> DecryptAsync(
	string cipherText,
	string key,
	SymmetricAlgorithm provider
)

Parameters

cipherText  String

The encrypted text to decrypt.

key  String

The key to decrypt the ciphertext.

provider  SymmetricAlgorithm

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.

Adapted from work by Frank Fong and William Rawls of the Code Project.

The cipher text can be any length other than 0; the key length must be at least MinKeyLength and no more than MaxKeyLength.
