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

Function Documentation

globus_gsi_cred_get_cert_type()

globus_result_t globus_gsi_cred_get_cert_type	(	globus_gsi_cred_handle_t	handle,
		globus_gsi_cert_utils_cert_type_t *	type
	)

Get the X.509 certificate 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

globus_gsi_cred_read()

globus_result_t globus_gsi_cred_read	(	globus_gsi_cred_handle_t	handle,
		X509_NAME *	desired_subject
	)

Read a credential.

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.

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_gsi_cred_read_cert()

globus_result_t globus_gsi_cred_read_cert	(	globus_gsi_cred_handle_t	handle,
		const char *	cert_filename
	)

Read a certificate chain from a file.

Read a cert from a file. Cert should be in PEM format. Will also read additional certificates as chain if present.

Parameters

[out]	handle	the handle to set based on the certificate that is read
[in]	cert_filename	the filename of the certificate to read

Returns

GLOBUS_SUCCESS or an error object identifier

globus_gsi_cred_read_cert_bio()

globus_result_t globus_gsi_cred_read_cert_bio	(	globus_gsi_cred_handle_t	handle,
		BIO *	bio
	)

Read a certificate chain from a 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_gsi_cred_read_cert_buffer()

globus_result_t globus_gsi_cred_read_cert_buffer	(	const char *	pem_buf,
		globus_gsi_cred_handle_t *	out_handle,
		X509 **	out_cert,
		STACK_OF(X509) **	out_cert_chain,
		char **	out_subject
	)

Read certificate chain from a buffer.

Read a cert from a buffer. Cert should be in PEM format. Will also read additional certificates as chain if present. Any parameter besides pem_buf may be NULL.

Parameters

pem_buf	The buffer containing the PEM formatted cert and chain.
out_handle	The handle to initialize and set cert on.
out_cert	The X509 certificate. This should be freed with X509_free().
out_cert_chain	The X509 certificate chain. This should be freed with sk_X509_free().
out_subject	The identity name of the cert. This should be freed with OPENSSL_free().

Returns

GLOBUS_SUCCESS or an error object identifier

globus_gsi_cred_read_key()

globus_result_t globus_gsi_cred_read_key	(	globus_gsi_cred_handle_t	handle,
		const char *	key_filename,
		int(*)()	pw_cb
	)

Read a private key.

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_gsi_cred_read_pkcs12()

globus_result_t globus_gsi_cred_read_pkcs12	(	globus_gsi_cred_handle_t	handle,
		const char *	pkcs12_filename
	)

Read certificate and key from a PKCS12 file.

Read a cert and 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_gsi_cred_read_proxy()

globus_result_t globus_gsi_cred_read_proxy	(	globus_gsi_cred_handle_t	handle,
		const char *	proxy_filename
	)

Read proxy credential.

Read a proxy from a PEM file.

Parameters

[in,out]	handle	The credential handle to set based on the proxy credential read from the file
[in]	proxy_filename	The file containing the proxy credential

Returns

GLOBUS_SUCCESS or an error object identifier

globus_gsi_cred_read_proxy_bio()

globus_result_t globus_gsi_cred_read_proxy_bio	(	globus_gsi_cred_handle_t	handle,
		BIO *	bio
	)

Read proxy credential from a 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

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_gsi_cred_write_proxy()

globus_result_t globus_gsi_cred_write_proxy	(	globus_gsi_cred_handle_t	handle,
		const char *	proxy_filename
	)

Write a proxy credential.

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.
