## Function Documentation

int hx509_ca_sign | ( | hx509_context | context,
|  | hx509_ca_tbs | tbs,
|  | hx509_cert | signer,
|  | hx509_cert * | certificate |
| ) |  |  |

Sign a to-be-signed certificate object with a issuer certificate.

The caller needs to at least have called the following functions on the to-be-signed certificate object:

- hx509_ca_tbs_init()
- hx509_ca_tbs_set_subject()
- hx509_ca_tbs_set_spki()

When done the to-be-signed certificate object should be freed with hx509_ca_tbs_free().

When creating self-signed certificate use hx509_ca_sign_self() instead.

Parameters:

  | context | A hx509 context.
  | tbs | object to be signed.
  | signer | the CA certificate object to sign with (need private key).
  | certificate | return cerificate, free with hx509_cert_free().

Returns:
  An hx509 error code, see hx509_get_error_string().

int hx509_ca_sign_self | ( | hx509_context | context,
|  | hx509_ca_tbs | tbs,
|  | hx509_private_key | signer,
|  | hx509_cert * | certificate |
| ) |  |  |

Work just like hx509_ca_sign() but signs it-self.

Parameters:

  | context | A hx509 context.
  | tbs | object to be signed.
  | signer | private key to sign with.
  | certificate | return cerificate, free with hx509_cert_free().

Returns:
  An hx509 error code, see hx509_get_error_string().

int hx509_ca_tbs_add_crl_dp_uri | ( | hx509_context | context,

| ) |  |  |

Add CRL distribution point URI to the to-be-signed certificate object.

Parameters:

  | context | A hx509 context.
  | tbs | object to be signed.
