Public Member Functions | |
void | Update (const byte *input, unsigned int length) |
process more input | |
unsigned int | DigestSize () const |
size of the hash returned by Final() | |
void | Final (byte *digest) |
compute hash for current message, then restart for a new message | |
void | Restart () |
discard the current state, and restart with a new message | |
void | TruncatedFinal (byte *digest, unsigned int digestSize) |
virtual byte * | CreateUpdateSpace (unsigned int &size) |
request space to write input into | |
virtual unsigned int | BlockSize () const |
block size of underlying compression function, or 0 if not block based | |
virtual unsigned int | OptimalBlockSize () const |
input to Update() should have length a multiple of this for optimal speed | |
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 void | CalculateTruncatedDigest (byte *digest, unsigned int digestSize, const byte *input, unsigned int length) |
truncated version of CalculateDigest() | |
virtual bool | TruncatedVerify (const byte *digest, unsigned int digestLength) |
truncated version of Verify() | |
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.
