DSA * d2i_DSAPublicKey(DSA **a, unsigned char **pp, long length);
DSA * d2i_DSAPrivateKey(DSA **a, unsigned char **pp, long length);
These two functions do not seem to be working. It doesn't initalize
the DSA structure from pp containing the DER encoded keys.
For example:
void main(int argc, char* argv[])
{
FILE* in = fopen(argv[1],"r"); /* open DER encoded key file */
unsigned char* key_buffer;
key_buffer=(unsigned char*) malloc(500);
int byteRead = fread(key_buffer, 1, 495, in);
printf("byteRead=%d\n",byteRead);
d2i_DSAPublicKey(dsa, &key_buffer, byteRead);
d2i_DSAPrivateKey(dsa, &key_buffer, byteRead);
/* this initializes properly:
d2i_DSA_PUBKEY_fp(in, dsa);
d2i_DSAPrivateKey_fp(in, dsa);
*/
/* this crashes because the DSA structure is not initalized correctly
by d2i_DSAPublicKey d2i_DSAPrivateKey
*/
printf("pub_key=%s\n",BN_bn2dec(dsa->pub_key));
printf("priv_key=%s\n",BN_bn2dec(dsa->priv_key));
fclose(in);
}
d2i_DSA_PUBKEY_fp() and d2i_DSAPrivateKey_fp() initializes
is there a fix for this or an alternative?
What I am looking for is a way to convert a DER encoded array to the
internal structure the crypto lib can use.
I am loading the DER encoded DSA key from a smartcard and storing it
into a BYTE array.
