Computes the transformation for the specified region of the specified byte array.

Namespace:   System.Security.Cryptography
Assembly:  mscorlib (in mscorlib.dll)

public byte[] TransformFinalBlock(
	byte[] inputBuffer,
	int inputOffset,
	int inputCount
)

Parameters

inputBuffer
Type: System.Byte[]

The input on which to perform the operation on.

inputOffset
Type: System.Int32

The offset into the byte array from which to begin using data from.

inputCount
Type: System.Int32

The number of bytes in the byte array to use as data.

Return Value

Type: System.Byte[]

The computed transformation.

Exception Condition
ArgumentNullException

The inputBuffer parameter is null.

ArgumentException

The inputOffset parameter is less than zero.

-or-

The inputCount parameter is less than zero.

-or-

The length of the input buffer is less than the sum of the input offset and the input count.

CryptographicException

The PKCS7 padding is invalid.

ArgumentOutOfRangeException

The inputOffset parameter is out of range. This parameter requires a non-negative number.

The following code example demonstrates how to call the TransformFinalBlock method to transform the final block of bytes. This code example is part of a larger example provided for the CryptoAPITransform class.

byte[] finalBytes = cryptoTransform.TransformFinalBlock(
    sourceBytes,
    currentPosition,
    sourceByteLength - currentPosition);
