Sha224 (Sha 224 secure hash algorithm) |
|
|
| Sha224 Class |
|
 |
|
|
Derived class from: Sha256
Implements hash algorithm SHA 224.
The class contains:
Constructors & Destructor
Initializer methods
Class methods
Class Constructors & Destructors
|
|
|
Sha224 (); |
| |
|
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.
|
|
|
|
Sha224 (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 Sha224 hash algorithm.
|
|
|
|
~Sha224 (); |
| |
|
Destroys the object and clears all common members. If working hash digest of 256 bits has been automatically created deletes working hash digest of 256 bits. |
|
|
|
void Initialize(void); [ Overridden, BaseHash virtual method defined and Sha256 member overridden ] |
| |
|
Initializes the hash object to perform the following hash operation.
|
|
|
|
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 Sha224 objects the value is 224 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 Sha224 objects the value is 28 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 Sha224 objects the value is 7 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. |
|
|
|
void SetWorkingDigest (BaseCryptoRandomStream* workDigest);
|
| |
|
Sets the BaseCryptoRandomStream workingDigest object to perform the hash computation of Sha256 base class.
|
|
|
|
unsigned short int GetWorkingDigestUCLength (void);
|
| |
|
Gets the working hash digest length for Sha224 hash algorithm object. In the case of Sha224 the working digest length in bytes (unsigned chars) is 32.
|
|
|
|
Hashes GetType(void); [ Overridden, BaseHash virtual method defined ] |
| |
|
Gets the hash algorithm type (the algorithm that implements) of the object.
Returns the Hashes value SHA_224.
