Detailed Description

Functions that plug into various plug points in the OpenSSL path validation mechanism. These functions add CRL checking, X509 Extension handling and proxy validation.

Function Documentation

int globus_gsi_callback_check_issued ( X509_STORE_CTX *  context,
X509 *  cert,
X509 *  issuer 
)

OpenSSL X509_check_issued() wrapper.

This function wraps the OpenSSL X509_check_issued() call and catches the error caused by the fact that a proxy certificate issuer may not have to have the correct KeyUsage fields set.

Parameters:
context The validation state object.
cert The certificate to check
issuer The issuer certificate to check
Returns:
1 on success 0 on failure

int globus_gsi_callback_create_proxy_callback ( int  preverify_ok,
X509_STORE_CTX *  x509_context 
)

Independent path validation callback.

This function provides a path validation callback for validation outside of a SSL session. It should be used in X509_STORE_set_verify_cb_func().

Parameters:
preverify_ok Communicates the result of default validation steps performed by OpenSSL
x509_context The validation state object
Returns:
1 on success 0 on failure

globus_result_t globus_gsi_callback_get_SSL_callback_data_index ( int *  index  ) 

Get callback data index from SSL structure.

Retrieve or create the index for our callback data structure in the SSL structure.

Parameters:
index Will contain the index upon return
Returns:
GLOBUS_SUCCESS unless an error occurred, in which case, a globus error object ID is returned

globus_result_t globus_gsi_callback_get_X509_STORE_callback_data_index ( int *  index  ) 

Get callback data index from X509_STORE.

Retrieve or create the index for our callback data structure in the X509_STORE.

Parameters:
index Will contain the index upon return
Returns:
GLOBUS_SUCCESS unless an error occurred, in which case, a globus error object ID is returned

int globus_gsi_callback_handshake_callback ( int  preverify_ok,
X509_STORE_CTX *  x509_context 
)

SSL path validation callback.

This function provides a path validation callback for the validation part of establishing a SSL session. It handles proxy certificates, X509 Extensions and CRL checking. It should be used in SSL_CTX_set_verify().

Parameters:
preverify_ok Communicates the result of default validation steps performed by OpenSSL
x509_context The validation state object.
Returns:
1 on success 0 on failure

int globus_gsi_callback_X509_verify_cert ( X509_STORE_CTX *  context,
void *  arg 
)

Certificate verify wrapper.

This function wraps the OpenSSL certificate verification callback for the purpose of a replacing the standard issuer check with one that deals with proxy certificates. Should be used with SSL_CTX_set_cert_verify_callback()

Parameters:
context The X509_STORE_CTX for which to register the callback.
arg Arguments to the callback. Currently ignored.
Returns:
1 on success 0 on failure
