Subject: [PATCH] Use extensions template from NSS
|
|
|
68c1c4 |
|
|
|
68c1c4 |
Drop certmonger's custom extension template and use the sequence of X509v3
|
|
|
68c1c4 |
extensions template from NSS.
|
|
|
68c1c4 |
|
|
|
68c1c4 |
The certmonger template had a bug that caused certmonger to create CSRs
|
|
|
68c1c4 |
with invalid DER. It was encoding extension's critical element even for
|
|
|
68c1c4 |
default value FALSE.
|
|
|
68c1c4 |
|
