Okay, I think I have a solution that can work for me :) I used the
https://curl.se/libcurl/c/CURLOPT_SSL_CTX_FUNCTION.html callback and I'm
reading the der file and adding it to the store, similar to the example in
the docs. It's something like this:
static CURLcode sslctx_function(CURL *curl, void *sslctx, void *parm) {
X509_STORE *store;
X509 *cert = NULL;
FILE *derCert = fopen("/data/misc/user/0/cacerts-added/924c6f19.0",
"r");
// Create cert from file
cert = d2i_X509_fp(derCert, NULL);
if(cert == NULL)
printf("d2i_X509_fp failed...\n");
/* get a pointer to the X509 certificate store (which may be empty) */
store = SSL_CTX_get_cert_store((SSL_CTX *)sslctx);
/* add our certificate to this store */
if(X509_STORE_add_cert(store, cert) == 0)
printf("error adding certificate\n");
/* decrease reference counts */
X509_free(cert);
/* all set to go */
return CURLE_OK;
}
Thanks all for your help!! I'm not sure if the thread needs to be marked as
solved or anything.
