Xenroll and OpenSSL

I want to use Xenroll to generate a keypair on a Windows system and submit the public key over HTTPS POST to an ApacheServer/Mod_SSL with a CGI invoking openssl ca for the signing. Thanks to Greg Stark's samples and the MS Xenroll site, I have been able to start on this task. I have a few questio

BIO pair

Hi   I have tried to use BIO pair and for some reason it doesn't seem to work right. So, here is the code if someone could tell me what's going wrong.   I have tried to make it work without SSL_set_fd and SSL_accept, but it won't work.       ssl = SSL_new (ctx);      SSL_set_fd (ssl, sd

Thank u Dr. Henson for the reply... My specific question is as follows... I want to set the public key in the certificate request (X509_REQ) structure. The draft for SCEP says that the public key has to be encoded to BER form and set it in the request... Can u help me in solving this puzzle of

Maurice Gittens' ReadPrivateKey(), ReadPublicKey(), etc.

I am trying to port pieces of OpenSSL to NetWare. I have been able to compile and link a program with the following function OK. RSA_private_decrypt(pubKeySize, input, buf_dec, privKey->pkey.rsa, RSA_PKCS1_PADDING); However, I would like alternative functions to ERR_load_crypto_strings(); //We

Hello again Dr. Henson, Once again thank u very much but I am still worried with the function which u pointed to... I have gone through the code of X509_REQ_set_pubkey( ) As far as I understood the function, it stores the public key in DER fromat as it uses the function i2d_PublicKey( ). I

INSTALL: Undefined reference

Hi, I'm installing openssl on win98 with mingw32. I run ms\mingw32. After seeing the line "Generating the DLLs and input libraries", I see the error: libeay32.exp(.edata+0x784):fake: undefined reference to `RAND_screen' libeay32.exp(.edata+0x237c):fake: undefined reference to `RA

Re: BIO pair

You seem to be forgetting, among other things, that if you use BIO pairs, you have _4_ streams of data to deal with, not 2. First there's data received on the socket that needs to go to the SSL engine. Then there's data from the SSL engine that you need to hand to the socket. Third there's th

Problems inastalling OpenSSL on AIX 4.3

Hi, I am relatively new to installing OpenSSL I have installed Perl on the machine (AIX 4.3.2.0) and have run the configure program using the following command: ./config --prefix=/opt/OpenSSL This seems to work ok but when I run the make command I get a number of warnings most of which are m

License Questions

Thanks for helping me with the problems I have been facing. I need to now address two problems that have remained for some time - I need to solve those now to automate the CA process. I have put in directives as I could understand from the documentation, but I am obviously making some mistake som
