You may find that reading the file test.cpp will help you quickly grab the
simpler concepts. There is a simple.h which will show you
default initialised algorithms. See test.cpp line 483 (approx, see below)
HmacFile for an implementation to start you off. It's trivial to replace
the hash algorithm in this case to pretty much whatever you wish
(it's currently SHA1). Change SHA1 to RIPEMD160 in the code below to start
you off.
void HmacFile(const char *hexKey, const char *file)
{
member_ptr<MessageAuthenticationCode> mac;
if (strcmp(hexKey, "selftest") == 0)
{
cerr << "Computing HMAC/SHA1 value for self test.\n";
mac.reset(NewIntegrityCheckingMAC());
}
else
{
std::string decodedKey;
StringSource(hexKey, true, new HexDecoder(new
StringSink(decodedKey)));
mac.reset(new HMAC<SHA1>((const byte *)decodedKey.data(),
decodedKey.size()));
}
FileSource(file, true, new HashFilter(*mac, new HexEncoder(new
FileSink(cout))));
}
