Hello openssl-users, I need to re-invent the Sipura's|Linksys's "gen_mc" utility which creates what they call a "Mini Certificate".
I've stuck at an attempt to use "RSA_sign()" properly. Is it at all possible to have an RSA object not generated with "RSA_generate_key()" but manually filled with the private key as the HEX buffer? I.e. without all accompanying "*p", "*q", "*n" and "*e" parameters and "*d" read from an external file? Can someone give an example code? The attached is my lame approach to the task. My idea was to split apart the example "MiniCert" from the Linksys's documentation to be able to learn which algorithm they use for signatures. (The documentation provides the base64-encoded CA's public and private keys, user's private key, the MiniCert, which is the concatenation of username, validity period, user's public key and CA's public key. I was able to extract CA's public key from the MiniCert, now I need to check where is the user's public key there and which signature was used...) The problem is: no matter that I replace the "RSA rsa->d" (the private key) part of RSA object with an example CA's private key - the RSA_sign() seems to re-create it's own one from p,q,n,e. -- Best regards, Tony mailto:[EMAIL PROTECTED]
