g_tls_certificate_new_from_pem ()

GTlsCertificate *
g_tls_certificate_new_from_pem (const gchar *data,
                                gssize length,
                                GError **error);

Creates a GTlsCertificate from the PEM-encoded data in data . If data includes both a certificate and a private key, then the returned certificate will include the private key data as well. (See the “private-key-pem” property for information about supported formats.)

The returned certificate will be the first certificate found in data . As of GLib 2.44, if data contains more certificates it will try to load a certificate chain. All certificates will be verified in the order found (top-level certificate should be the last one in the file) and the “issuer” property of each certificate will be set accordingly if the verification succeeds. If any certificate in the chain cannot be verified, the first certificate in the file will still be returned.

Since 2.28

g_tls_certificate_new_from_file ()

GTlsCertificate *
g_tls_certificate_new_from_file (const gchar *file,
                                 GError **error);

Creates a GTlsCertificate from the PEM-encoded data in file . The returned certificate will be the first certificate found in file . As of GLib 2.44, if file contains more certificates it will try to load a certificate chain. All certificates will be verified in the order found (top-level certificate should be the last one in the file) and the “issuer” property of each certificate will be set accordingly if the verification succeeds. If any certificate in the chain cannot be verified, the first certificate in the file will still be returned.

If file cannot be read or parsed, the function will return NULL and set error . Otherwise, this behaves like g_tls_certificate_new_from_pem().

Since 2.28

g_tls_certificate_new_from_files ()

GTlsCertificate *
g_tls_certificate_new_from_files (const gchar *cert_file,
                                  const gchar *key_file,
                                  GError **error);

Creates a GTlsCertificate from the PEM-encoded data in cert_file and key_file . The returned certificate will be the first certificate found in cert_file . As of GLib 2.44, if cert_file contains more certificates it will try to load a certificate chain. All certificates will be verified in the order found (top-level certificate should be the last one in the file) and the “issuer” property of each certificate will be set accordingly if the verification succeeds. If any certificate in the chain cannot be verified, the first certificate in the file will still be returned.

If either file cannot be read or parsed, the function will return NULL and set error . Otherwise, this behaves like g_tls_certificate_new_from_pem().

Since 2.28

g_tls_certificate_list_new_from_file ()

GList *
g_tls_certificate_list_new_from_file (const gchar *file,
                                      GError **error);

Creates one or more GTlsCertificates from the PEM-encoded data in file . If file cannot be read or parsed, the function will return NULL and set error . If file does not contain any PEM-encoded certificates, this will return an empty list and not set error .

Since 2.28

g_tls_certificate_get_issuer ()

GTlsCertificate *
g_tls_certificate_get_issuer (GTlsCertificate *cert);

Gets the GTlsCertificate representing cert 's issuer, if known

Since 2.28

g_tls_certificate_verify ()

GTlsCertificateFlags
g_tls_certificate_verify (GTlsCertificate *cert,
                          GSocketConnectable *identity,
                          GTlsCertificate *trusted_ca);

This verifies cert and returns a set of GTlsCertificateFlags indicating any problems found with it. This can be used to verify a certificate outside the context of making a connection, or to check a certificate against a CA that is not part of the system CA database.

If identity is not NULL, cert 's name(s) will be compared against it, and G_TLS_CERTIFICATE_BAD_IDENTITY will be set in the return value if it does not match. If identity is NULL, that bit will never be set in the return value.

If trusted_ca is not NULL, then cert (or one of the certificates in its chain) must be signed by it, or else G_TLS_CERTIFICATE_UNKNOWN_CA will be set in the return value. If trusted_ca is NULL, that bit will never be set in the return value.

(All other GTlsCertificateFlags values will always be set or unset as appropriate.)

Since 2.28

g_tls_certificate_is_same ()

gboolean
g_tls_certificate_is_same (GTlsCertificate *cert_one,
                           GTlsCertificate *cert_two);

Check if two GTlsCertificate objects represent the same certificate. The raw DER byte data of the two certificates are checked for equality. This has the effect that two certificates may compare equal even if their “issuer”, “private-key”, or “private-key-pem” properties differ.

Since 2.34

GTlsCertificate

typedef struct _GTlsCertificate GTlsCertificate;

Abstract base class for TLS certificate types.

Since 2.28

The “certificate” property

  “certificate”              GByteArray *

The DER (binary) encoded representation of the certificate. This property and the “certificate-pem” property represent the same data, just in different forms.

Flags: Read / Write / Construct Only

Since 2.28

The “certificate-pem” property

  “certificate-pem”          gchar *

The PEM (ASCII) encoded representation of the certificate. This property and the “certificate” property represent the same data, just in different forms.

Flags: Read / Write / Construct Only

Default value: NULL

Since 2.28

The “issuer” property

  “issuer”                   GTlsCertificate *

A GTlsCertificate representing the entity that issued this certificate. If NULL, this means that the certificate is either self-signed, or else the certificate of the issuer is not available.

Flags: Read / Write / Construct Only

Since 2.28

The “private-key” property

  “private-key”              GByteArray *

The DER (binary) encoded representation of the certificate's private key, in either PKCS#1 format or unencrypted PKCS#8 format. This property (or the “private-key-pem” property) can be set when constructing a key (eg, from a file), but cannot be read.

PKCS#8 format is supported since 2.32; earlier releases only support PKCS#1. You can use the openssl rsa tool to convert PKCS#8 keys to PKCS#1.

Flags: Write / Construct Only

Since 2.28

The “private-key-pem” property

  “private-key-pem”          gchar *

The PEM (ASCII) encoded representation of the certificate's private key in either PKCS#1 format ("BEGIN RSA PRIVATE KEY") or unencrypted PKCS#8 format ("BEGIN PRIVATE KEY"). This property (or the “private-key” property) can be set when constructing a key (eg, from a file), but cannot be read.

PKCS#8 format is supported since 2.32; earlier releases only support PKCS#1. You can use the openssl rsa tool to convert PKCS#8 keys to PKCS#1.

Flags: Write / Construct Only

Default value: NULL
