1=pod 2 3=head1 NAME 4 5X509_get_serialNumber, 6X509_get0_serialNumber, 7X509_set_serialNumber 8- get or set certificate serial number 9 10=head1 SYNOPSIS 11 12 #include <openssl/x509.h> 13 14 ASN1_INTEGER *X509_get_serialNumber(X509 *x); 15 const ASN1_INTEGER *X509_get0_serialNumber(const X509 *x); 16 int X509_set_serialNumber(X509 *x, ASN1_INTEGER *serial); 17 18=head1 DESCRIPTION 19 20X509_get_serialNumber() returns the serial number of certificate B<x> as an 21B<ASN1_INTEGER> structure which can be examined or initialised. The value 22returned is an internal pointer which B<MUST NOT> be freed up after the call. 23 24X509_get0_serialNumber() is the same as X509_get_serialNumber() except it 25accepts a const parameter and returns a const result. 26 27X509_set_serialNumber() sets the serial number of certificate B<x> to 28B<serial>. A copy of the serial number is used internally so B<serial> should 29be freed up after use. 30 31=head1 RETURN VALUES 32 33X509_get_serialNumber() and X509_get0_serialNumber() return an B<ASN1_INTEGER> 34structure. 35 36X509_set_serialNumber() returns 1 for success and 0 for failure. 37 38=head1 SEE ALSO 39 40L<d2i_X509(3)>, 41L<ERR_get_error(3)>, 42L<X509_CRL_get0_by_serial(3)>, 43L<X509_get0_signature(3)>, 44L<X509_get_ext_d2i(3)>, 45L<X509_get_extension_flags(3)>, 46L<X509_get_pubkey(3)>, 47L<X509_get_subject_name(3)>, 48L<X509_NAME_add_entry_by_txt(3)>, 49L<X509_NAME_ENTRY_get_object(3)>, 50L<X509_NAME_get_index_by_NID(3)>, 51L<X509_NAME_print_ex(3)>, 52L<X509_new(3)>, 53L<X509_sign(3)>, 54L<X509V3_get_d2i(3)>, 55L<X509_verify_cert(3)> 56 57=head1 HISTORY 58 59The X509_get_serialNumber() and X509_set_serialNumber() functions are 60available in all versions of OpenSSL. 61The X509_get0_serialNumber() function was added in OpenSSL 1.1.0. 62 63=head1 COPYRIGHT 64 65Copyright 2016 The OpenSSL Project Authors.
