.. \*(C` and \*(C' are quotes in nroff, nothing in troff, for use with C<>.
. ds C` "" . ds C' "" 'br\} . ds C` . ds C' 'br\}
Escape single quotes in literal strings from groff's Unicode transform.

If the F register is >0, we'll generate index entries on stderr for
titles (.TH), headers (.SH), subsections (.SS), items (.Ip), and index
entries marked with X<> in POD. Of course, you'll have to process the
output yourself in some meaningful fashion.

Avoid warning from groff about undefined register 'F'.

Title "X509_GET_SERIALNUMBER 3ossl" For nroff, turn off justification. Always turn off hyphenation; it makes
way too many mistakes in technical documents.
X509_get_serialNumber, X509_get0_serialNumber, X509_set_serialNumber, X509_ACERT_get0_serialNumber, X509_ACERT_set1_serialNumber \- get or set certificate serial number Header "SYNOPSIS" .Vb 1 #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); \& #include <openssl/x509_acert.h> \& ASN1_INTEGER *X509_ACERT_get0_serialNumber(X509_ACERT *x); int X509_ACERT_set1_serialNumber(X509_ACERT *x, ASN1_INTEGER *serial); .Ve Header "DESCRIPTION" \fBX509_get_serialNumber() returns the serial number of certificate x as an \fBASN1_INTEGER structure which can be examined or initialised. The value returned is an internal pointer which MUST NOT be freed up after the call.

\fBX509_get0_serialNumber() is the same as X509_get_serialNumber() except it accepts a const parameter and returns a const result.

\fBX509_set_serialNumber() sets the serial number of certificate x to \fBserial. A copy of the serial number is used internally so serial should be freed up after use.

\fBX509_ACERT_get0_serialNumber() performs the same operation as \fBX509_get_serialNumber() for attribute certificates.

\fBX509_ACERT_set1_serialNumber() performs the same operation as \fBX509_set_serialNumber() for attribute certificates.

Header "RETURN VALUES" \fBX509_get_serialNumber(), X509_get0_serialNumber() and \fBX509_ACERT_get0_serialNumber() return a pointer to an ASN1_INTEGER structure.

\fBX509_set_serialNumber() and X509_ACERT_set1_serialNumber() return 1 for success and 0 for failure.

The X509_get0_serialNumber() function was added in OpenSSL 1.1.0. The X509_ACERT_get0_serialNumber() and X509_ACERT_set1_serialNumber() functions were added in OpenSSL 3.4.
