libressl-X509_get_serialNumber3
Get or set certificate serial number
Usage
Crypto Library (libcrypto, -lcrypto)
#include <openssl/x509.h>
ASN1_INTEGER *
X509_get_serialNumber(X509 *x);
const ASN1_INTEGER *
X509_get0_serialNumber(const X509 *x);
int
X509_set_serialNumber(X509 *x, ASN1_INTEGER *serial);
Overview
X509_get_serialNumber() returns the serial number of certificate x as an ASN1_INTEGER structure which can be examined or initialised. The value returned is an internal pointer which must not be freed up after the call.
X509_get0_serialNumber() does the same except that it accepts a constant argument and returns a constant result.
X509_set_serialNumber() sets the serial number of certificate x to serial. A copy of the serial number is used internally so serial should be freed up after use.
Return values
X509_get_serialNumber() and X509_get0_serialNumber() return a pointer to an ASN1_INTEGER structure.
X509_set_serialNumber() returns 1 for success or 0 for failure. In some cases of failure, the reason can be determined with ERR_get_error(3).
