## Description

## Functions

### xmlSecNssKeyDataX509GetKlass ()

    xmlSecKeyDataId
    xmlSecNssKeyDataX509GetKlass (void);

The NSS X509 key data klass (http://www.w3.org/TR/xmldsig-core/sec-X509Data).

#### Returns

the X509 data klass.

### xmlSecNssKeyDataX509GetKeyCert ()

    CERTCertificate *
    xmlSecNssKeyDataX509GetKeyCert (xmlSecKeyDataPtr data);

Gets the certificate from which the key was extracted.

#### Parameters

data | the pointer to X509 key data. |

#### Returns

the key's certificate or NULL if key data was not used for key extraction or an error occurs.

### xmlSecNssKeyDataX509AdoptKeyCert ()

    int

Adds certificate to the X509 key data and sets the it as the key's certificate in `data` . On success, the `data` owns the cert.

#### Parameters

data | the pointer to X509 key data. |
cert | the pointer to NSS X509 certificate. |

#### Returns

0 on success or a negative value if an error occurs.

### xmlSecNssKeyDataX509AdoptCert ()

    int

Gets a certificate from X509 key data.

#### Parameters

data | the pointer to X509 key data. |
pos | the desired certificate position. |

#### Returns

the pointer to certificate or NULL if `pos` is larger than the number of certificates in `data` or an error occurs.

### xmlSecNssKeyDataX509GetCertsSize ()

    xmlSecSize
    xmlSecNssKeyDataX509GetCertsSize (xmlSecKeyDataPtr data);

Gets the number of certificates in `data` .

#### Parameters

data | the pointer to X509 key data. |

#### Returns

te number of certificates in `data` .

### xmlSecNssKeyDataX509AdoptCrl ()

    int
    xmlSecNssKeyDataX509AdoptCrl (xmlSecKeyDataPtr data,
                                  CERTSignedCrl *crl);

Adds CRL to the X509 key data.

#### Parameters

data | the pointer to X509 key data. |
crl | the pointer to NSS X509 CRL. |

#### Returns

0 on success or a negative value if an error occurs.

### xmlSecNssKeyDataX509GetCrl ()

    CERTSignedCrl *
    xmlSecNssKeyDataX509GetCrl (xmlSecKeyDataPtr data,
                                xmlSecSize pos);

Gets a CRL from X509 key data.

#### Parameters

data | the pointer to X509 key data. |
pos | the desired CRL position. |

#### Returns

the pointer to CRL or NULL if `pos` is larger than the number of CRLs in `data` or an error occurs.

### xmlSecNssKeyDataX509GetCrlsSize ()

    xmlSecSize
    xmlSecNssKeyDataX509GetCrlsSize (xmlSecKeyDataPtr data);

Gets the number of CRLs in `data` .

#### Parameters

data | the pointer to X509 key data. |

#### Returns

te number of CRLs in `data` .

### xmlSecNssX509CertGetKey ()

    xmlSecKeyDataPtr
    xmlSecNssX509CertGetKey (CERTCertificate *cert);
