Parameters

inputBuffer

The input to compute to base 64.

inputOffset

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

inputCount

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

outputBuffer

The output to which to write the result.

outputOffset

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

Returns

The number of bytes written.

Remarks

The System.Security.Cryptography.ToBase64Transform class is a block algorithm that processes input blocks of 3 bytes and creates output blocks of 4 bytes. The ToBase64Transform.TransformBlock(Byte[], int, int, Byte[], int) method transforms an input block of 24 bits into 32 bits of character data. You must maintain 3 byte input boundaries to 4 byte output boundaries in order to match the block transform.
