Implementation of a simple mechanism for authenticating requests. If enabled (it's disabled by default), the Janus admin API can be used to specify valid tokens; each request must then contain a valid token string, or otherwise the request is rejected with an error. Whether tokens should be shared across users or not is completely up to the controlling application: these tokens are completely opaque to Janus, and treated as strings, which means Janus will only check if the token exists or not when asked.

Function Documentation

janus_auth_add_token()

gboolean janus_auth_add_token

(

const char *

token

)

Method to add a new valid token for authenticating.

Parameters

[in]

token

The new valid token

Returns

TRUE if the operation was successful, FALSE otherwise

janus_auth_allow_plugin()

gboolean janus_auth_allow_plugin	(	const char *	token,
		janus_plugin *	plugin )

Method to allow a token to use a plugin.

Parameters

[in]	token	The token that can now access this plugin
[in]	plugin	Opaque pointer to the janus_plugin instance this token can access

Returns

TRUE if the operation was successful, FALSE otherwise

janus_auth_check_plugin()

gboolean janus_auth_check_plugin	(	const char *	token,
		janus_plugin *	plugin )

Method to check whether a provided token can access a specified plugin.

Note

verifies both token signatures and against stored tokens

Parameters

[in]	token	The token to check
[in]	plugin	The plugin to check as an opaque pointer to a janus_plugin instance

Returns

TRUE if the token is allowed to access the plugin, FALSE otherwise

janus_auth_check_signature()

gboolean janus_auth_check_signature	(	const char *	token,
		const char *	realm )

Method to check whether a signed token is valid.

Parameters

[in]	token	The token to validate
[in]	realm	The token realm

Returns

TRUE if the signature is valid and not expired, FALSE otherwise

janus_auth_check_signature_contains()

gboolean janus_auth_check_signature_contains	(	const char *	token,
		const char *	realm,
		const char *	desc )

Method to verify a signed token contains a descriptor.

Parameters

[in]	token	The token to validate
[in]	realm	The token realm
[in]	desc	The descriptor to search for

Returns

When the token based authentication is enabled: TRUE if the token is valid, not expired and contains the descriptor, FALSE otherwise. When the token based authentication is disabled: always TRUE.

janus_auth_check_token()

gboolean janus_auth_check_token

(

const char *

token

)

Method to check whether a provided token is valid or not.

Note

verifies both token signatures and against stored tokens

Parameters

[in]

token

The token to validate

Returns

TRUE if the token is valid, FALSE otherwise

janus_auth_deinit()

void janus_auth_deinit

(

void

)

Method to de-initialize the mechanism.

janus_auth_disallow_plugin()

gboolean janus_auth_disallow_plugin	(	const char *	token,
		janus_plugin *	plugin )

Method to disallow a token to use a plugin.

Parameters

[in]	token	The token this operation refers to
[in]	plugin	Opaque pointer to the janus_plugin instance this token can not access anymore

Returns

TRUE if the operation was successful, FALSE otherwise

janus_auth_init()

void janus_auth_init	(	gboolean	enabled,
		const char *	secret )

Method to initializing the token based authentication.

Parameters

[in]	enabled	Whether the authentication mechanism should be enabled or not
[in]	secret	the secret to validate signed tokens against, or NULL to use stored tokens
