X509_GET_SERIALNUMBER(3) OpenSSL X509_GET_SERIALNUMBER(3)
 

X509_get_serialNumber, X509_get0_serialNumber, X509_set_serialNumber - get or set certificate serial number

 #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);

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() is the same as X509_get_serialNumber() except it accepts a const parameter and returns a const 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.

X509_get_serialNumber() and X509_get0_serialNumber() return an ASN1_INTEGER structure.
X509_set_serialNumber() returns 1 for success and 0 for failure.

X509_get_serialNumber() and X509_set_serialNumber() are available in all versions of OpenSSL. X509_get0_serialNumber() was added in OpenSSL 1.1.0.
