Namespace: CryptoSysPKI
Assembly: diCrSysPKINet (in diCrSysPKINet.dll) Version: 23.0.0.30549 (23.1.0.0)

Syntax

public static string Unpad(
	string inputHex,
	CipherAlgorithm cipherAlg,
	Padding pad = Padding.Pkcs5
)

Public Shared Function Unpad ( 
	inputHex As String,
	cipherAlg As CipherAlgorithm,
	Optional pad As Padding = Padding.Pkcs5
) As String

Parameters

inputHex String: Hex-encoded padded data
cipherAlg CipherAlgorithm: Block cipher being used
pad Padding (Optional): Padding method to use (default is PKCS#5/#7)

Return Value

String
Unpadded data in hex-encoded string.

Unless pad is NoPad, the unpadded output is always shorter than the padded input. An error is indicated by returning the original data. If the output length equals the input length, then error.
