Github is warning users about a security issue with pycroptodome < 3.6.6.:

Apparently, there's some sort of vulnerability with older versions:
https://nvd.nist.gov/vuln/detail/CVE-2018-15560
Is this something that should be changed on this package to allow installations with pycroptodome ~> 3.6.6.?
Btw, related to #2
