NAME

6       X509_get_serialNumber, X509_get0_serialNumber, X509_set_serialNumber -
7       get or set certificate serial number
8

SYNOPSIS

10        #include <openssl/x509.h>
11
12        ASN1_INTEGER *X509_get_serialNumber(X509 *x);
13        const ASN1_INTEGER *X509_get0_serialNumber(const X509 *x);
14        int X509_set_serialNumber(X509 *x, ASN1_INTEGER *serial);
15

DESCRIPTION

17       X509_get_serialNumber() returns the serial number of certificate x as
18       an ASN1_INTEGER structure which can be examined or initialised. The
19       value returned is an internal pointer which MUST NOT be freed up after
20       the call.
21
22       X509_get0_serialNumber() is the same as X509_get_serialNumber() except
23       it accepts a const parameter and returns a const result.
24
25       X509_set_serialNumber() sets the serial number of certificate x to
26       serial. A copy of the serial number is used internally so serial should
27       be freed up after use.
28

RETURN VALUES

30       X509_get_serialNumber() and X509_get0_serialNumber() return an
31       ASN1_INTEGER structure.
32
33       X509_set_serialNumber() returns 1 for success and 0 for failure.
