- Public Member Functions inherited from CryptoHashSink
 CryptoHashSink ()=default
 Create a null hash sink.
 
int blockSize () const
 Block size of the hash sum in bytes.
 
- Public Member Functions inherited from HashSink

long long skip (long long count)
 Read and discard count bytes.
 
void drain (const Bytes &auxBuffer=Bytes{})
 Read everything that is left.
 
long readSpan (Out< Bytes > buffer)
 Read fixed number of bytes.
 
String readSpan (long count)
 Read a fixed number of bytes.
 
String readAll ()
 Read the entire stream.
 
- Public Member Functions inherited from Object
 Object ()=default
 Create a null object.
 
 operator bool () const
 Check if this is a non-null object.
 
bool isNull () const
