php - Issues with encryping with OpenSSL on one side and decryping with CryptoPP [AES-128] -

im having issues encryption/decryption different cipher suites.

on 1 hand, using php encrypt string:

base64_encode(openssl_encrypt($data, "aes-128-cbc", $password, openssl_raw_data, "0123456789abdefg")); 

and on other hand, decrypting cryptopp:

std::string decrypted = decrypt(dl_notdecrypted, decryption_key, "0123456789abdefg"); 

the function "decrypt":

std::string decrypt(const std::string& str_in, const std::string& key, const std::string& iv) {      std::string str_out;     cryptopp::cbc_mode<cryptopp::aes>::decryption decryption((byte*)key.c_str(), key.length(), (byte*)iv.c_str());     cryptopp::stringsource decryptor(str_in, true,         new cryptopp::base64decoder(             new cryptopp::streamtransformationfilter(decryption,                 new cryptopp::stringsink(str_out)                 )             )         );     return str_out; } 

it fails "unknown exception". guessing padding issue openssl, have no clue how supposed fix this.

if there available this, nice. thanks.
