Represents an X.509 public key certificate as defined in RFC 5280.
It provides access to the standard fields of an X.509 certificate including version, serial number, validity period, distinguished names, and signature algorithm.
| Property | Description |
|---|---|
issuerDN: String (read-only) | Returns the X.500 distinguished name of the entity that signed this certificate. |
notAfter: Date (read-only) | Returns the end date of the certificate validity period. |
notBefore: Date (read-only) | Returns the start date of the certificate validity period. |
serialNumber: String (read-only) | Returns the certificate serial number in string format. |
sigAlgName: String (read-only) | Returns the algorithm used to sign this certificate. |
subjectDN: String (read-only) | Returns the X.500 distinguished name of the entity this certificate belongs to. |
version: Number (read-only) | Returns the X.509 certificate version number. |
This class does not have a constructor, so you cannot create it directly.
| Method | Description |
|---|---|
| getIssuerDN() | Returns the X.500 distinguished name of the entity that signed this certificate. |
| getNotAfter() | Returns the end date of the certificate validity period. |
| getNotBefore() | Returns the start date of the certificate validity period. |
| getSerialNumber() | Returns the certificate serial number in string format. |
| getSigAlgName() | Returns the algorithm used to sign this certificate. |

(read-only)Returns the X.500 distinguished name of the entity that signed this certificate.
(read-only)Returns the end date of the certificate validity period.
(read-only)Returns the start date of the certificate validity period.
(read-only)Returns the certificate serial number in string format. The serial number is a unique positive integer assigned by the CA to each certificate.

(read-only)Returns the X.500 distinguished name of the entity this certificate belongs to.
(read-only)Returns the X.509 certificate version number.
Returns the X.500 distinguished name of the entity that signed this certificate.
Returns:
