Going back to the original (from test.cpp), it looks like there's a
typo:
FileSource pubFile(pubFilename, true, new HexEncoder);
To confirm the typo, run "cryptest.exe r" to invoke the original
routines.
Jeff
string RSAEncryptString(const char *pubFilename, const char *seed,
const char *message)
{
FileSource pubFile(pubFilename, true, new HexDecoder);
RSAES_OAEP_SHA_Encryptor pub(pubFile);
RandomPool randPool;
randPool.IncorporateEntropy((byte *)seed, strlen(seed));
string result;
StringSource(message, true, new PK_EncryptorFilter(randPool, pub, new
HexEncoder(new StringSink(result))));
return result;
}
