Detailed Description
       Read/Write a GSI Credential Handle.

       This section defines operations to read and write GSI Credential handles.

Function Documentation
   globus_result_t globus_gsi_cred_read (globus_gsi_cred_handle_thandle, X509_NAME *desired_subject)
       Read a Credential from a filesystem location. The credential to read will be determined by the search order specified in the handle
       attributes.

       Parameters:
	   handle The credential handle to set. This credential handle should already be initialized using globus_gsi_cred_handle_init.
	   desired_subject The subject to check for when reading in a credential. The desired_subject should be either a exact match of the read
	   cert's subject or should just contain the /CN entry. If null, the credential read in is the first match based on the system
	   configuration (paths and environment variables)

       Returns:
	   GLOBUS_SUCCESS if no errors occured, otherwise, an error object identifier is returned.

       See also:
	   globus_gsi_cred_read_proxy()

	   globus_gsi_cred_read_cert_and_key()

       Note:
	   This function always searches for the desired credential. If you don't want to perform a search, then don't use this function. The
	   search goes in the order of the handle attributes' search order.

   globus_result_t globus_gsi_cred_read_proxy (globus_gsi_cred_handle_thandle, const char *proxy_filename)
       Read a proxy from a PEM file. Parameters:
	   handle The credential handle to set based on the proxy credential read from the file
	   proxy_filename The file containing the proxy credential

       Returns:
	   GLOBUS_SUCCESS or an error object identifier

   globus_result_t globus_gsi_cred_read_proxy_bio (globus_gsi_cred_handle_thandle, BIO *bio)
       Read a Proxy Credential from a BIO stream and set the credential handle to represent the read credential. The values read from the stream,
       in order, will be the signed certificate, the private key, and the certificate chain

       Parameters:
	   handle The credential handle to set. The credential should handle be initialized (i.e. not NULL).
	   bio The stream to read the credential from

       Returns:
	   GLOBUS_SUCCESS unless an error occurred, in which case an error object is returned

   globus_result_t globus_gsi_cred_read_key (globus_gsi_cred_handle_thandle, char *key_filename, int(*)()pw_cb)
       Read a key from a PEM file. Parameters:
	   handle the handle to set based on the key that is read
	   key_filename the filename of the key to read
	   pw_cb the callback for obtaining a password for decrypting the key.

       Returns:
	   GLOBUS_SUCCESS or an error object identifier

   globus_result_t globus_gsi_cred_read_cert (globus_gsi_cred_handle_thandle, char *cert_filename)
       Read a cert from a file. Cert should be in PEM format. Will also read additional certificates as chain if present.

       Parameters:
	   handle the handle to set based on the certificate that is read
	   cert_filename the filename of the certificate to read

       Returns:
	   GLOBUS_SUCCESS or an error object identifier

   globus_result_t globus_gsi_cred_read_cert_bio (globus_gsi_cred_handle_thandle, BIO *bio)
       Read a cert from a BIO. Cert should be in PEM format. Will also read additional certificates as chain if present.

       Parameters:
	   handle the handle to set based on the certificate that is read
	   bio the bio to read the certificate from

       Returns:
	   GLOBUS_SUCCESS or an error object identifier

   globus_result_t globus_gsi_cred_read_pkcs12 (globus_gsi_cred_handle_thandle, char *pkcs12_filename)
       Read a cert & key from a file. The file should be in PKCS12 format.

       Parameters:
	   handle the handle to populate with the read credential
	   pkcs12_filename the filename containing the credential to read

       Returns:
	   GLOBUS_SUCCESS or an error object identifier

   globus_result_t globus_gsi_cred_write (globus_gsi_cred_handle_thandle, BIO *bio)
       Write out a credential to a BIO. The credential parameters written, in order, are the signed certificate, the RSA private key, and the
       certificate chain (a set of X509 certificates). the credential is written out in PEM format.

       Parameters:
	   handle The credential to write out
	   bio The BIO stream to write out to

       Returns:
	   GLOBUS_SUCCESS unless an error occurred, in which case an error object ID is returned.

   globus_result_t globus_gsi_cred_write_proxy (globus_gsi_cred_handle_thandle, char *proxy_filename)
       Write out a credential to a file. The credential parameters written, in order, are the signed certificate, the RSA private key, and the
       certificate chain (a set of X509 certificates). the credential is written out in PEM format.

       Parameters:
	   handle The credential to write out
	   proxy_filename The file to write out to

       Returns:
	   GLOBUS_SUCCESS unless an error occurred, in which case an error object ID is returned.

   globus_result_t globus_gsi_cred_get_cert_type (globus_gsi_cred_handle_thandle, globus_gsi_cert_utils_cert_type_t *type)
       Determine the type of the given X509 certificate For the list of possible values returned, see globus_gsi_cert_utils_cert_type_t.
       Parameters:
	   handle The credential handle containing the certificate
	   type The returned X509 certificate type

       Returns:
	   GLOBUS_SUCCESS or an error captured in a globus_result_t
