Hi,
I generated a key pair on Crypto++ & encrypted a text message (public
key) and now I'm trying to decrypt it using the private key (converted
into PEM) on OpenSSL (PHP).
at that I got the following error from OpenSSL:
error:0406506C:rsa routines:RSA_EAY_PRIVATE_DECRYPT:data greater than
mod len
Encrypt and decrypt via Crypto++ is working perfectly
Encrypt and decrypt via OpenSSL with the same keys converted into PEM
format is also working.
Why are Crypto++ and OpenSSL not interoperable and whats the
distinction between the two?
The message is encrypted that way:
string RSAEncryptString(const char *publickey, const char *message)
{
FileSource pubFile(privatkey, true, new HexDecoder);
RSAES_OAEP_SHA_Encryptor pub(pubFile);
string result;
StringSource(message, true, new PK_EncryptorFilter(GlobalRNG(), pub,
new Base64Encoder(new StringSink(result))));
return result;
}
What can I do to make them interoperable? regards JKolitz.
