void | Update (const byte *input, size_t length) |
process more input | |
unsigned int | DigestSize () const |
should not be called on PK_MessageAccumulator | |
void | TruncatedFinal (byte *digest, size_t digestSize) |
should not be called on PK_MessageAccumulator | |
HashTransformation & | Ref () |
return a reference to this object, useful for passing a temporary object to a function that takes a non-const reference | |
virtual byte * | CreateUpdateSpace (size_t &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 | |
unsigned int | TagSize () const |
same as DigestSize() | |
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 unsigned int | OptimalDataAlignment () const |
returns how input should be aligned for optimal performance | |
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() | |
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 | |

virtual void HashTransformation::Final | ( | byte * | digest | ) | [inline, virtual, inherited] |
compute hash for current message, then restart for a new message
Definition at line 545 of file cryptlib.h.
Referenced by PKCS5_PBKDF2_HMAC< T >::DeriveKey(), and HMAC_Base::TruncatedFinal().
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.
