Package: libcrypto++6
Version: 5.6.4-8
Followup-For: Bug #932620
Came up against the same problem. Test case below:
================================================================
// Build with
// $ make LDFLAGS=$(pkg-config --libs libcrypto++) cryptopp-link
#include <iostream>
#include <crypto++/blake2.h>
#include <crypto++/hex.h>
#define DIGEST_SIZE CryptoPP::BLAKE2b::DIGESTSIZE
static std::string
hash_key (const std::list<std::string> &key)
{
CryptoPP::BLAKE2b hasher(DIGEST_SIZE);
for (auto& s : key)
{
hasher.Update(reinterpret_cast<const byte *>(s.data()),
s.size());
}
byte digest[DIGEST_SIZE];
hasher.Final(&digest[0]);
std::string digest_str;
CryptoPP::HexEncoder(new CryptoPP::StringSink(digest_str))
.Put(&digest[0], DIGEST_SIZE);
return digest_str;
}
int main (int argc, char **argv)
{
std::list<std::string> key;
for (int i = 0; i < argc; ++i)
{
key.push_back (argv[i]);
}
std::string hash( hash_key(key) );
std::cout << hash << std::endl;
return 0;
}
