| SapphireHash (unsigned int hashLength=20) | |
| void | Update (const byte *input, unsigned int length) |
| process more input | |
| void | TruncatedFinal (byte *hash, unsigned int size) |
| truncated version of Final() | |
| unsigned int | DigestSize () const |
| size of the hash returned by Final() | |
| virtual byte * | CreateUpdateSpace (unsigned int &size) |
| request space to write input into | |
| virtual void | Final (byte *digest) |
| compute hash for current message, then restart for a new message | |
| virtual void | Restart () |
| discard the current state, and restart with a new message | |
| virtual unsigned int | OptimalBlockSize () const |
| input to Update() should have length a multiple of this for optimal speed | |
| virtual unsigned int | OptimalDataAlignment () const |
| returns how input should be aligned for optimal performance | |
| virtual void | CalculateDigest (byte *digest, const byte *input, unsigned int length) |
| use this if your input is in one piece and you don't want to call Update() and Final() separately | |
| virtual bool | Verify (const byte *digest) |
| verify that digest is a valid digest for the current message, then reinitialize the object | |
| virtual bool | VerifyDigest (const byte *digest, const byte *input, unsigned int length) |
| use this if your input is in one piece and you don't want to call Update() and Verify() separately | |

| virtual bool | VerifyTruncatedDigest (const byte *digest, unsigned int digestLength, const byte *input, unsigned int length) |
| truncated version of VerifyDigest() | |
| virtual std::string | AlgorithmName () const |
| returns name of this algorithm, not universally implemented yet | |
| virtual Clonable * | Clone () const |
| this is not implemented by most classes yet | |

verify that digest is a valid digest for the current message, then reinitialize the object Default implementation is to call Final() and do a bitwise comparison between its output and digest. Definition at line 532 of file cryptlib.h. |
