Thanks for your answer. I already solved the problem another way without
involving BIO,
but using ASN1 and BIGNUM convertion funtions. Below is the simple code I used:
char * serialHex;
BIGNUM *serialBN = NULL;
...
serialBN = ASN1_INTEGER_to_BN(X509_get_serialNumber(cert),NULL);
serialHex = BN_bn2hex(serialBN);
The above gives me a hexadecimal representation of the serial number stored in
a char
variable.
That is what I initially wanted to achieve.
Thanks for your help.
