Detailed Description
Credential Handle Management.
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* 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.

passed in should be a valid X509 certificate object
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

globus_result_t globus_gsi_cred_set_key (globus_gsi_cred_handle_t handle, 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 (globus_gsi_cred_handle_t handle)
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 (globus_gsi_cred_handle_t cred_handle,
globus_gsi_callback_data_t callback_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 (globus_gsi_cred_handle_t cred_handle,
globus_gsi_callback_data_t callback_data_in, time_t check_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
