Description
This class implements a Poco::DigestEngine for all digest algorithms supported by OpenSSL.
Inheritance
Direct Base Classes: Poco::DigestEngine
All Base Classes: Poco::DigestEngine
Member Summary
Member Functions: algorithm, digest, digestLength, nid, reset, updateImpl
Inherited Functions: constantTimeEquals, digest, digestFromHex, digestLength, digestToHex, reset, update, updateImpl
Constructors
DigestEngine
DigestEngine(
const std::string & name
);
Creates a DigestEngine using the digest with the given name (e.g., "MD5", "SHA1", "SHA256", "SHA512", etc.). See the OpenSSL documentation for a list of supported digest algorithms.
Throws a Poco::NotFoundException if no algorithm with the given name exists.
Destructor
~DigestEngine 
~DigestEngine();
Destroys the DigestEngine.
Member Functions
algorithm 
const std::string & algorithm() const;
Returns the name of the digest algorithm.
digest
const Poco::DigestEngine::Digest & digest();
digestLength
std::size_t digestLength() const;
See also: Poco::DigestEngine::digestLength()
nid
int nid() const;
Returns the NID (OpenSSL object identifier) of the digest algorithm.
reset
void reset();
See also: Poco::DigestEngine::reset()
updateImpl 
void updateImpl(
const void * data,
std::size_t length
);
