[c++] load X509 certificate

[GRU Samuel]

Hi, The certificate is well formed  because i can open it in windows 2000. I have this code :     string cert="certificate.der";     OpenSSLCryptoX509* x509 = NULL;     if (!cert.empty())     {         x509 = new OpenSSLCryptoX509();         ifstream s(cert.c_str());         string buf;         char ch;         while ((ch=s.get())!=EOF)             buf+=ch;         x509->loadX509Base64Bin(buf.data(),buf.length());     } I have a problem when i call the loadX509Base64Bin method. I have the exception XSECCryptoException. I doesn't work. I don't understand every thing in this method ! Can someone explain me, please ?     EVP_ENCODE_CTX m_dctx;     EVP_DecodeInit(&m_dctx); ----> buf contains data and len = 460     int rc = EVP_DecodeUpdate(&m_dctx,                           outBuf,                           &bufLen,                           (unsigned char *) buf,                           len);  ---->  rc = 0 but  bufLen = 0 and outBuf is empty .   Is it normal ?     if (rc < 0) {         throw XSECCryptoException(XSECCryptoException::Base64Error,             "OpenSSL:Base64 - Error during Base64 Decode of X509 Certificate");     }     int finalLen;     rc = EVP_DecodeFinal(&m_dctx, &outBuf[bufLen], &finalLen);     bufLen += finalLen; ---->  finalLen = 0 so bufLen = 0 .   It isn't normal ? ----> so after, we have the exception !!!     if (bufLen > 0) {         mp_X509=  d2i_X509(NULL, &outBuf, bufLen);     }     // Check to see if we have a certificate....     if (mp_X509 == NULL) {         throw XSECCryptoException(XSECCryptoException::X509Error,         "OpenSSL:X509 - Error transating Base64 DER encoding into OpenSSL X509 structure");     } Thank you.
