/* X509_REQ_INFO is handled in an unusual way to get round
|
|
* invalid encodings. Some broken certificate requests don't
|
|
* encode the attributes field if it is empty. This is in
|
|
* violation of PKCS#10 but we need to tolerate it. We do
|
|
* this by making the attributes field OPTIONAL then using
|
|
* the callback to initialise it to an empty STACK.
|
|
*
|
|
* This means that the field will be correctly encoded unless
|
|
* we NULL out the field.
|
|
*
|
|
* As a result we no longer need the req_kludge field because
|
|
* the information is now contained in the attributes field:
|
|
* 1. If it is NULL then it's the invalid omission.
|
|
* 2. If it is empty it is the correct encoding.
|
|
* 3. If it is not empty then some attributes are present.
