Invalid arn us-west-1

[troyfactor4]

Greetings,

First off, thanks for creating this great tool. Can't wait to start using it. I'm having an issue perhaps you can assist. After a compile I ran the test command from the README and here is the result:

OpenSSL version: "OpenSSL 1.1.1 11 Sep 2018"

openssl pkey -engine ./target/release/libopenssl_engine_kms.so -inform engine -in arn:aws:kms:us-west-1:<redacted aws id>:key/<redacted key guid> -pubout -text
engine "kms" set.
[2020-04-08T20:14:06Z ERROR openssl_engine_kms] load key err for key id arn:aws:kms:us-west-1:<redacted aws id>:key/<redacted key guid>: Invalid arn us-west-1

unable to load key

I've tried using just the GUID for the key instead of the full ARN. In this case it seems it does not read my AWS config for region and defaults to eu-west-1.

openssl pkey -engine ./target/release/libopenssl_engine_kms.so -inform engine -in <redacted key guid> -pubout -text
engine "kms" set.

Any suggestions for me? Can I help debug somehow?

This fixed it for me:
