64 | /*- |
65 | * X509_REQ_INFO is handled in an unusual way to get round | |
9d6b1ce6 DSH |
66 | * invalid encodings. Some broken certificate requests don't |
67 | * encode the attributes field if it is empty. This is in | |
68 | * violation of PKCS#10 but we need to tolerate it. We do | |
69 | * this by making the attributes field OPTIONAL then using | |
70 | * the callback to initialise it to an empty STACK. | |
71 | * | |
72 | * This means that the field will be correctly encoded unless | |
73 | * we NULL out the field. | |
74 | * | |
75 | * As a result we no longer need the req_kludge field because | |
76 | * the information is now contained in the attributes field: | |
77 | * 1. If it is NULL then it's the invalid omission. | |
78 | * 2. If it is empty it is the correct encoding. | |
79 | * 3. If it is not empty then some attributes are present. | |
