DESCRIPTION

28       The ne_ssl_clicert_read function reads a client certificate from a
29       PKCS#12-formatted file, and returns an ne_ssl_client_cert object. If
30       the client certificate is encrypted, it must be decrypted before it is
31       used. An ne_ssl_client_cert object holds a client certificate and the
32       associated private key, not just a certificate; the term "client
33       certificate" will used to refer to this pair.
34
35       A client certificate can be in one of two states: encrypted or
36       decrypted. The ne_ssl_clicert_encrypted function will return non-zero
37       if the client certificate is in the encrypted state. A client
38       certificate object returned by ne_ssl_clicert_read may be initially in
39       either state, depending on whether the file was encrypted or not.
40
41       ne_ssl_clicert_decrypt can be used to decrypt a client certificate
42       using the appropriate password. This function must only be called if
43       the object is in the encrypted state; if decryption fails, the
44       certificate state does not change, so decryption can be attempted more
45       than once using different passwords.
46
47       A client certificate can be given a "friendly name" when it is created;
48       ne_ssl_clicert_name will return this name (or NULL if no friendly name
49       was specified).  ne_ssl_clicert_name can be used when the client
50       certificate is in either the encrypted or decrypted state, and will
51       return the same string for the lifetime of the object.
52
53       The function ne_ssl_clicert_owner returns the certificate part of the
54       client certificate; it must only be called if the client certificate is
55       in the decrypted state.
56
57       When the client certificate is no longer needed, the
58       ne_ssl_clicert_free function should be used to destroy the object.
59

RETURN VALUE

61       ne_ssl_clicert_read returns a client certificate object, or NULL if the
62       file could not be read.  ne_ssl_clicert_encrypted returns zero if the
63       object is in the decrypted state, or non-zero if it is in the encrypted
64       state.  ne_ssl_clicert_name returns a NUL-terminated friendly name
65       string, or NULL.  ne_ssl_clicert_owner returns a certificate object.
66

EXAMPLES

68       The following code reads a client certificate and decrypts it if
69       necessary, then loads it into an HTTP session.
70
71           ne_ssl_client_cert *ccert;
72
73           ccert = ne_ssl_clicert_read("/path/to/client.p12");
74
75           if (ccert == NULL) {
76              /* handle error... */
77           } else if (ne_ssl_clicert_encrypted(ccert)) {
78              char *password = prompt_for_password();
79
80              if (ne_ssl_clicert_decrypt(ccert, password)) {
81                 /* could not decrypt! handle error... */
82              }
83           }
84
85           ne_ssl_set_clicert(sess, ccert);
