byte[] decryptUpdate(byte[] InBuffer, int InIndex, int InSize, int OutSize);

Parameters

InBuffer - buffer with data to decrypt.
InIndex - offset of the encrypted data block in InBuffer.
InSize - size of encrypted data in bytes.
OutBuffer - buffer where the decrypted data should be stored.
OutIndex - offset in OutBuffer, starting from which the data should be written.
OutSize - the amount of space available in OutBuffer in bytes.
