Detailed Description

Create/Destroy/Modify a GSI Credential Handle.

Within the Globus GSI Credential Library, all credential operations require a handle parameter. Currenlty only one operation may be in progress at once per credential handle.

This section defines operations to create, modify and destroy GSI Credential handles.

Typedef Documentation

typedef struct globus_l_gsi_cred_handle_s* globus_gsi_cred_handle_t

GSI Credential Handle. A GSI Credential handle keeps track of state relating to a credential. Handles can have immutable attributes associated with them. All credential operations take a credential handle pointer as a parameter.

Function Documentation

globus_result_t globus_gsi_cred_handle_init (globus_gsi_cred_handle_t * handle, globus_gsi_cred_handle_attrs_t handle_attrs)

Initializes a credential handle to be used credential handling functions. Takes a set of handle attributes that are immutable to the handle. The handle attributes are only pointed to by the handle, so the lifetime of the attributes needs to be as long as that of the handle.

Parameters:

handle The handle to be initialized
handle_attrs The immutable attributes of the handle

Returns:

GLOBUS_SUCCESS or an error captured in a globus_result_t

globus_result_t globus_gsi_cred_handle_destroy (globus_gsi_cred_handle_t handle)

handle The credential handle to be destroyed

Returns:

GLOBUS_SUCCESS

globus_result_t globus_gsi_cred_handle_copy (globus_gsi_cred_handle_t source, globus_gsi_cred_handle_t * dest)

globus_result_t globus_gsi_cred_get_cert (globus_gsi_cred_handle_t handle, X509 ** cert)

Get the certificate of a credential. Parameters:

handle The credential handle to get the certificate from
cert The resulting X509 certificate, a duplicate of the certificate in the credential handle. This variable should be freed when the user is finished with it using the function X509_free.

Returns:

GLOBUS_SUCCESS if no error, otherwise an error object id is returned

globus_result_t globus_gsi_cred_set_key (globus_gsi_cred_handle_t handle, EVP_PKEY * key)
