Detailed Description
this class provides an API to calculate various cryptographic hash functions
Member Function Documentation
| virtual void cppcms::crypto::message_digest::append | ( | void const * | ptr, |
| size_t | size | ||
| ) | [pure virtual] |
Add more data of size bytes for processing
| virtual unsigned cppcms::crypto::message_digest::block_size | ( | ) | const [pure virtual] |
Get processing block size, returns 64 or 128, used mostly for correct HMAC calculations
| virtual message_digest* cppcms::crypto::message_digest::clone | ( | ) | const [pure virtual] |
Make a polymorphic copy of this object, note the state of copied object is reset to initial
| static std::auto_ptr<message_digest> cppcms::crypto::message_digest::create_by_name | ( | std::string const & | name | ) | [static] |
Create message digest by name, more then sha1 and md5 may be supported, if CppCMS is compiled with cryptography library like libgcrypt or openssl
| virtual unsigned cppcms::crypto::message_digest::digest_size | ( | ) | const [pure virtual] |
Get the size of message digest, for example for MD5 it is 16, for SHA1 it is 20
| static std::auto_ptr<message_digest> cppcms::crypto::message_digest::md5 | ( | ) | [static] |
Create MD5 message digest
| virtual char const* cppcms::crypto::message_digest::name | ( | ) | const [pure virtual] |
Get the name of the hash function
| virtual void cppcms::crypto::message_digest::readout | ( | void * | ptr | ) | [pure virtual] |
Read the message digest for the data and reset it into initial state, provided buffer must be digest_size() bytes
| static std::auto_ptr<message_digest> cppcms::crypto::message_digest::sha1 | ( | ) | [static] |
Create SHA1 message digest
