This directory contains the certificates for the tests targeting the enforcement of the policy indicated by the *pathLenConstraint* field. All leaf elements were generated with *is_ca* unset and all roots with the *selfsign=1* option.
1. zero pathlen constraint on an intermediate CA (invalid)
```
cert11.crt -> cert12.crt (max_pathlen=0) -> cert13.crt -> cert14.crt
```
2. zero pathlen constraint on the root CA (invalid)
```
cert21.crt (max_pathlen=0) -> cert22.crt -> cert23.crt
```
3. nonzero pathlen constraint on the root CA (invalid)
```
cert31.crt (max_pathlen=1) -> cert32.crt -> cert33.crt -> cert34.crt
```
4. nonzero pathlen constraint on an intermediate CA (invalid)
```
cert41.crt -> cert42.crt (max_pathlen=1) -> cert43.crt -> cert44.crt -> cert45.crt
```
5. nonzero pathlen constraint on an intermediate CA with maximum number of elements in the chain (valid)
```
cert51.crt -> cert52.crt (max_pathlen=1) -> cert53.crt -> cert54.crt
```
6. nonzero pathlen constraint on the root CA with maximum number of elements in the chain (valid)
```
cert61.crt (max_pathlen=1) -> cert62.crt -> cert63.crt
```
7. pathlen constraint on the root CA with maximum number of elements and a self signed certificate in the chain (valid)
(This situation happens for example when a root of some hierarchy gets integrated into another hierarchy. In this case the certificates issued before the integration will have an intermadiate self signed certificate in their chain)
```
cert71.crt (max_pathlen=1) -> cert72.crt -> cert73.crt (self signed) -> cert74.crt -> cert74.crt
```
Add test case for first intermediate max_pathlen=0
!!! This test case is currently failing !!!
(See fix in next-next commit.)
