||
| 4 | * Pure-PHP X.509 Parser |
||
| 5 | * |
||
| 6 | * PHP version 5 |
||
| 7 | * |
||
| 8 | * Encode and decode X.509 certificates. |
||
| 9 | * |
||
| 10 | * The extensions are from {@link http://tools.ietf.org/html/rfc5280 RFC5280} and |
||
| 11 | * {@link http://web.archive.org/web/19961027104704/http://www3.netscape.com/eng/security/cert-exts.html Netscape Certificate Extensions}. |
||
| 12 | * |
||
| 13 | * Note that loading an X.509 certificate and resaving it may invalidate the signature. The reason being that the signature is based on a |
||
| 14 | * portion of the certificate that contains optional parameters with default values. ie. if the parameter isn't there the default value is |
||
| 15 | * used. Problem is, if the parameter is there and it just so happens to have the default value there are two ways that that parameter can |
||
| 16 | * be encoded. It can be encoded explicitly or left out all together. This would effect the signature value and thus may invalidate the |
||
| 17 | * the certificate all together unless the certificate is re-signed. |
