globus_gsi_cred_read_cert (3)

Read/Write a GSI Credential Handle.

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

globus_result_t globus_gsi_cred_get_cert_type (\fBglobus_gsi_cred_handle_t\fPhandle, 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_result_t globus_gsi_cred_read (\fBglobus_gsi_cred_handle_t\fPhandle, 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.

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_cert (\fBglobus_gsi_cred_handle_t\fPhandle, 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:

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 (\fBglobus_gsi_cred_handle_t\fPhandle, 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_result_t globus_gsi_cred_read_cert_buffer (char *pem_buf, \fBglobus_gsi_cred_handle_t\fP *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_result_t globus_gsi_cred_read_key (\fBglobus_gsi_cred_handle_t\fPhandle, 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_result_t globus_gsi_cred_read_pkcs12 (\fBglobus_gsi_cred_handle_t\fPhandle, 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_result_t globus_gsi_cred_read_proxy (\fBglobus_gsi_cred_handle_t\fPhandle, const char *proxy_filename)

Read proxy credential. 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 (\fBglobus_gsi_cred_handle_t\fPhandle, 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

globus_result_t globus_gsi_cred_write (\fBglobus_gsi_cred_handle_t\fPhandle, BIO *bio)

Write Credential. 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 (\fBglobus_gsi_cred_handle_t\fPhandle, 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.
