							|  |  |  | =head1 DESCRIPTION | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | X509_get_serialNumber() returns the serial number of certificate B<x> as an | 
					
						
							|  |  |  | B<ASN1_INTEGER> structure which can be examined or initialised. The value | 
					
						
							|  |  |  | returned is an internal pointer which B<MUST NOT> be freed up after the call. | 
					
						
							|  |  |  | 
 | 
					
						
							| 
									
										
										
										
											2016-08-18 22:16:31 +08:00
										 |  |  | X509_get0_serialNumber() is the same as X509_get_serialNumber() except it | 
					
						
							|  |  |  | accepts a const parameter and returns a const result. | 
					
						
							|  |  |  | 
 | 
					
						
							| 
									
										
										
										
											2016-03-14 08:23:13 +08:00
										 |  |  | X509_set_serialNumber() sets the serial number of certificate B<x> to | 
					
						
							|  |  |  | B<serial>. A copy of the serial number is used internally so B<serial> should | 
					
						
							|  |  |  | be freed up after use. | 
					
						
							|  |  |  | 
 |

											2016-08-18 22:16:31 +08:00
										 |  |  | X509_get_serialNumber() and X509_get0_serialNumber() return an B<ASN1_INTEGER> |
