3 parties also depend on the situation. If the purpose of the script is dispensable, then naturally...
Some practical 3rd parties can be added without any problem. There's no need to copy them to the system; just call them with relative paths...
choice and MD5 are both very practical. But choice doesn't directly bring set /P
This depends on the trade-off. Using 3rd parties for the interface is not recommended.
But since it's done, posting it for collection or something is not bad, but for application,
at least I wouldn't use it.
