Declaration
void ProcessHeader()TransformBlock(byte[], int, int, byte[], int)
Transforms the specified region of the input byte array and copies the resulting transform to the specified region of the output byte array.
Declaration
int TransformBlock(byte[] inputBuffer, int inputOffset, int inputCount, byte[] outputBuffer, int outputOffset)Parameters
inputBuffer
byte[]

inputCount
The number of bytes in the input byte array to use as data.
outputBuffer
byte[]
The output to which to write the transform.
outputOffset
The offset into the output byte array from which to begin writing data.
Returns
The number of bytes written.
TransformFinalBlock(byte[], int, int)
