[erlang-questions] Comodo PositiveSSL certificates with Cowboy 1.x
Fri Dec 30 13:03:02 CET 2016
I don't remember the exact details, but you should have received a zip file
with a set of certificates. This zip file should contain
1. your certificate (foo_com.crt)
2. a set of intermediary certificates (intermediate1.crt, intermediate2.crt)
3. the root certificate (root.crt)
You will need to concatenate all the intermediaries starting from the last
one into what's called a intermediary certificate chain:
cat intermediate2.crt intermediate1.crt > chain.crt
The configuration of cowboy is then done using the `certfile` and `
cacertfile` options, for example:
These options are specified in the documentation of the Erlang SSL app (
Hope this helps,
