Implement support for custom correlation-id-length and correlation-id-nonce-length values

[philipsinnott]

Hi!

Currently, interactions are solely received if we use the default correlation-id-length and correlation-id-nonce-length values in our Interactsh serverconfig.yaml file, since the same lengths must be used on both sides (client and server).

When testing, this is oftentimes not optimal due to various reasons. It would be awesome if support for using customized lengths could be added as a configuration option, so that we can use shorter URLs.

Thanks!

Thanks for the feature request. This should be pretty easy to add.
