# Captain ALM Network Library Tester (Java)
This is the tester for the [calmnetlib](https://code.mrmelon54.xyz/alfred/calmnetlib) java library.
This is the tester for the [calmnetlib](https://code.mrmelon54.com/alfred/calmnetlib) java library.
There is a keystore file with the password keystore containing a self-signed localhost certificate for testing.
