Public Member Functions

 hashoflow (int alg=sha1_c)
 ctor, does an implicit open
 
virtual ~hashoflow ()
 dtor
 
virtual bool failed (void) const
 in failed state?
 
virtual size_t write (const byte_t *_buf, size_t _size)
 writes a few bytes
 
void open (int alg=sha1_c)
 opens a new hashing session, closing any previous one, if any
 
void close (void)
 close the current link, throwing away the hash
 
void close (scopira::tool::basic_array< byte_t > &hash)
 close the current link, storing the final hash into the given buffer
