feature: randHex

[consideRatio]

As ConfigMaps etc doesn't handle bytes well and some software having support for parsing hexadecimal characters into their wanted bytes configuration, it can be useful to have a randHex function that can be used to autogenerate such passwords.

I've created a workaround randHex named template for use in the Helm chart I maintain:
