CipherUnpad(Byte, CipherAlgorithm, Padding) Method

Remove padding from an encryption block.

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

Syntax

public static byte[] Unpad(
	byte[] input,
	CipherAlgorithm cipherAlg,
	Padding pad = Padding.Pkcs5
)

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

Parameters

input Byte: Padded data
cipherAlg CipherAlgorithm: Block cipher being used
pad Padding (Optional): Padding method to use (default is PKCS#5/#7)

Return Value

Byte
Unpadded data in byte array.

Remarks

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.
