Detailed Description

Create/Destroy/Modify a GSI Credential Handle.

Within the Globus GSI Credential Library, all credential operations require a handle parameter. Currently 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* \fBglobus_gsi_cred_handle_t\fP

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.

Parameters:

handle The credential handle to set the certificate on

cert The X509 cert to set in the cred handle. The cert passed in can be NULL which will set the cert in the handle to NULL, freeing the current cert in the handle.

Returns:

GLOBUS_SUCCESS or an error object id if an error

handle The handle containing the certificate chain field to set

cert_chain The certificate chain to set the handle's certificate chain to

Returns:

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

globus_result_t globus_gsi_cred_set_key (\fBglobus_gsi_cred_handle_t\fPhandle, EVP_PKEY *key)

Set the credential's private key. Set the private key of the credential handle.

Parameters:

handle The handle on which to set the key.

key The private key to set the handle's key to. This value can be NULL, in which case the current handle's key is freed.

globus_result_t globus_gsi_cred_verify (\fBglobus_gsi_cred_handle_t\fPhandle)

Verify a credential. This function checks that the certificate is signed by the public key of the issuer cert (the first cert in the chain). Note that this function DOES NOT check the private key or the public of the certificate, as stated in a previous version of the documentation.

Parameters:

handle The credential handle containing the certificate and key to be validated

Returns:

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

globus_result_t globus_gsi_cred_verify_cert_chain (\fBglobus_gsi_cred_handle_t\fPcred_handle, globus_gsi_callback_data_tcallback_data)

Verify credential. This function performs path validation on the certificate chain contained in the credential handle.

Parameters:

cred_handle The credential handle containing the certificate chain to be validated

callback_data A initialized callback data structure

Returns:

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

globus_result_t globus_gsi_cred_verify_cert_chain_when (\fBglobus_gsi_cred_handle_t\fPcred_handle, globus_gsi_callback_data_tcallback_data_in, time_tcheck_time)

Verify credential at a specific time. This function performs path validation on the certificate chain contained in the credential handle. Expiration checks are done at the time given.

Parameters:

cred_handle The credential handle containing the certificate chain to be validated

callback_data_in A callback data structure. If NULL, one will be initialized with only the default cert dir set.

check_time Check if the cert chain was valid at this time. Set to 0 to use a time that the cert is valid, essentially bypassing the expiration check.

Returns:

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