   Digest::ClassMethods
 
  Overview
The Digest::ClassMethods module is used in the concrete subclass of Digest
that does not require arguments in its construction.
The modules adds convenient class methods as Digest::MD5.digest, Digest::MD5.hexdigest.
Defined in:
digest/digest.crInstance Method Summary
- 
        #base64digest(data) : String
        
          Returns the base64-encoded hash of data. 
- 
        #base64digest(& : self -> _) : String
        
          Yields a context object with an #update(data : String | Bytes)method available.
- 
        #digest(data) : Bytes
        
          Returns the hash of data. 
- 
        #digest(& : self -> ) : Bytes
        
          Yields an instance of selfwhich can receive calls to#update(data : String | Bytes)and returns the finalized digest afterwards.
- 
        #hexdigest(data) : String
        
          Returns the hexadecimal representation of the hash of data. 
- 
        #hexdigest(& : self -> ) : String
        
          Yields a context object with an #update(data : String | Bytes)method available.
