Class Constructors & Destructors

		Ripemd160 ();
		Creates an object of the base class, sets the default values for common members. Before the object can be used, BaseCryptoRandomStream hashStream must be assigned and the hash must be initialized.

Ripemd160 (BaseCryptoRandomStream* hashStream); [ Inherited from BaseHash ]

Creates an object of the base class, sets the default values for common members of all derived classes and sets the BaseCryptoRandomStream hashStream object (Message Digest stream) passed as the digest that will be used by the object Ripemd160 hash algorithm.

		~Ripemd160 ();
		Destroys the object and clears all common members.

Class Initializer

		virtual void Initialize(void); [ Overridden inherited BaseRipemd member ]
		It must initialize the hash object to perform a new hash operation.

Class Methods

		*void Add(BaseCryptoRandomStream dataStream);** [ Inherited from BaseRipemd ]
		Adds the BaseCryptoRandomStream dataStream object to hash and hashes it with all previous added BaseCryptoRandomStream dataStream objects.

		void Finalize(void); [ Inherited from BaseRipemd ]
		Finalizes the hash computation with all added BaseCryptoRandomStream dataStream objects.

unsigned short int GetBitHashLength(void); [ Overridden, BaseHash virtual method defined ]

Gets the Hash stream length measured in bits that the specific hash algorithm works with, with Ripemd160 objects the value is 160 bits.

unsigned short int GetUCHashLength(void); [ Overridden, BaseHash virtual method defined ]

Gets the Hash stream length measured in bytes (unsigned chars) that the specific hash algorithm works with, with Ripemd160 objects the value is 20 unsigned chars (1 byte).

unsigned short int GetULHashLength(void); [ Overridden, BaseHash virtual method defined ]

Gets the Hash stream length measured in 4 bytes (usigned long ints) that the specific hash algorithm works with, with Ripemd160 objects the value is 5 unsigned long ints (4 bytes).

		void SetMessageDigest (BaseCryptoRandomStream* hashStream); [ Inherited from BaseHash ]
		Sets the BaseCryptoRandomStream hashStream object (Message Digest stream) passed as the digest that will be used by the specific hash algorithm.

		*BaseCryptoRandomStream GetMessageDigest (void);** [ Inherited from BaseHash ]
		Gets the BaseCryptoRandomStream hashStream object used by the hash algorithm object.

		Hashes GetType(void); [ Overridden, BaseHash virtual method defined ]
		Gets the hash algorithm type (the algorithm that implements) of the object. Returns the Hashes value RIPEMD_160.

Protected methods

		*void AddMessageLength (unsigned long int length)*;
		Adds messaage length processed, if it is greater than unsigned long makes use of another usigned long to store overflow. Total length will be used while finalizing the hash operation.

		*void Transform_F0 (unsigned long int, unsigned long int, unsigned long int, unsigned long int, unsigned long int, unsigned long int);*
		Performs the first transformation set for Ripemd 160 and Ripemd 320.

		*void Transform_G1 (unsigned long int, unsigned long int, unsigned long int, unsigned long int, unsigned long int, unsigned long int);*
		Performs the second transformation set for Ripemd 160 and Ripemd 320.

		*void Transform_H2 (unsigned long int, unsigned long int, unsigned long int, unsigned long int, unsigned long int, unsigned long int);*
		Performs the third transformation set for Ripemd 160 and Ripemd 320.

		*void Transform_I3 (unsigned long int, unsigned long int, unsigned long int, unsigned long int, unsigned long int, unsigned long int);*
		Performs the fourth transformation set for Ripemd 160 and Ripemd 320.

		*void Transform_J4 (unsigned long int, unsigned long int, unsigned long int, unsigned long int, unsigned long int, unsigned long int);*
		Performs the fifth transformation set for Ripemd 160 and Ripemd 320.

		*void Transform_J5 (unsigned long int, unsigned long int, unsigned long int, unsigned long int, unsigned long int, unsigned long int);*
		Performs the sixth transformation set for Ripemd 160 and Ripemd 320.

		*void Transform_I6 (unsigned long int, unsigned long int, unsigned long int, unsigned long int, unsigned long int, unsigned long int);*
		Performs the seventh transformation set for Ripemd 160 and Ripemd 320.

		*void Transform_H7 (unsigned long int, unsigned long int, unsigned long int, unsigned long int, unsigned long int, unsigned long int);*
		Performs the eighth transformation set for Ripemd 160 and Ripemd 320.

		*void Transform_G8 (unsigned long int, unsigned long int, unsigned long int, unsigned long int, unsigned long int, unsigned long int);*
		Performs the ninth transformation set for Ripemd 160 and Ripemd 320.

		*void Transform_F9 (unsigned long int, unsigned long int, unsigned long int, unsigned long int, unsigned long int, unsigned long int);*
		Performs the tenth transformation set for Ripemd 160 and Ripemd 320.

Private methods

		*void Compress (BaseCryptoRandomStream hashDigest, unsigned char* dataStream);** [ Overridden, BaseRipemd160X virtual method defined ]
		Computes the dataStream chunk block of information with the hashDigest.
