Public Member Functions | |
void | TruncatedFinal (byte *hash, size_t size) |
truncated version of Final() | |
unsigned int | DigestSize () const |
size of the hash returned by Final() | |
Clonable * | Clone () const |
this is not implemented by most classes yet | |
std::string | AlgorithmName () const |
returns name of this algorithm, not universally implemented yet | |
ByteOrder | GetByteOrder () const |
unsigned int | BlockSize () const |
block size of underlying compression function, or 0 if not block based | |
unsigned int | OptimalBlockSize () const |
input to Update() should have length a multiple of this for optimal speed | |
unsigned int | OptimalDataAlignment () const |
returns how input should be aligned for optimal performance | |
void | Update (const byte *input, size_t length) |
process more input | |
byte * | CreateUpdateSpace (size_t &size) |
request space to write input into | |
void | Restart () |
discard the current state, and restart with a new message | |
HashTransformation & | Ref () |
return a reference to this object, | |
virtual void | Final (byte *digest) |
compute hash for current message, then restart for a new message | |
virtual void | CalculateDigest (byte *digest, const byte *input, size_t 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, size_t 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, size_t digestSize, const byte *input, size_t length) |
truncated version of CalculateDigest() | |
virtual bool | TruncatedVerify (const byte *digest, size_t digestLength) |
truncated version of Verify() | |
virtual bool | VerifyTruncatedDigest (const byte *digest, size_t digestLength, const byte *input, size_t length) |
truncated version of VerifyDigest() | |

HashTransformation& HashTransformation::Ref | ( | ) | [inline, inherited] |
return a reference to this object,
This function is useful for passing a temporary HashTransformation object to a function that takes a non-const reference.

compute hash for current message, then restart for a new message

virtual bool HashTransformation::Verify | ( | const byte * | digest | ) | [inline, virtual, inherited] |
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.
