Hi All, I'm having a bit of a problem. I need to load a private key (EC, but
I'm having the same problem with RSA) from an unecrypted, der encoded, PKCS8
memory buffer. I'm just trying to get it to work loading from a file for now
and it's simply not working. Can someone tell me what I'm doing wrong?
I'm generating the key like this:
openssl ecparam -name sect571r1 -genkey | openssl pkcs8 -topk8 -nocrypt -inform
pem -outform der -out ec_key.pk8
And my little test program is this:
#include <errno.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <openssl/pem.h>
#include <openssl/evp.h>
#include <openssl/ssl.h>
int main(int argc, char **argv) {
OpenSSL_add_all_algorithms();
SSL_load_error_strings();
FILE *f = fopen(argv[1], "r");
if(f == NULL) {
printf("File open failed: %s\n", strerror(errno));
exit(EXIT_FAILURE);
}
EVP_PKEY *key = d2i_PKCS8PrivateKey_fp(f, NULL, NULL, NULL);
if(key == NULL) {
ERR_print_errors_fp(stdout);
exit(EXIT_FAILURE);
}
}
The output is this:
3074066056:error:0D0680A8:asn1 encoding routines:ASN1_CHECK_TLEN:wrong
tag:tasn_dec.c:1319:
3074066056:error:0D07803A:asn1 encoding routines:ASN1_ITEM_EX_D2I:nested asn1
