Greetings,
I'm attempting to test compatibility between Crypto++ 4.2 and OpenSSL 0.9.6g, both
under Win2k. I would like to exchange keys (and the encrypted data) between the two.
>From Crypto++, I create a DES EDE3 (CBC mode) key using the following:
...
DES_EDE3_Encryption en(key);
CBC_CTS_Encryptor encryptor(en, iv);
....
then write the key to file using:
memcpy(&keyStruct->key_iv[0], key, DES_EDE3_KEYSIZE);
memcpy(&keyStruct->key_iv[(int)DES_EDE3_KEYSIZE], iv,
DES_EDE3_Encryption::BLOCKSIZE);
FileSink fs1(payloadFileName);
fs1.Put((const byte *) &keyResult->key_iv [0], sizeof(keyResult->key_iv));
I am able to encrypt and decrypt messages successfully within Crypto++ with the
resulting file.
Problem is when using OpenSSL to encrypt messages using the key from Crypto++.
>From OpenSSL (the Crypto++ key is in file "crypto_des", plaintext is in
>"smalltext.txt", ciphertext to "des_ssl") :
> openssl enc -in smalltext.txt -e -kfile crypto_des -out des_ssl -des-ede3-cbc
> -nosalt
No success in decrypting the result (in des_ssl ) within Crypto++.
I am sure this must be a problem with OpenSSL or my usage of it. But has anyone else
tried this?
Regards.
