The YYID software does nothing more than generating a random string. In any programming language.

• Generates a random string in UUID#4 format: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
• In contrast to RFC 4122, it uses all digits (128bit)
• Uses a crytographically solid source of randomness

• Provide a solution for generating random strings
• Demonstrate how to create and use a package in the language's package management system
• Demonstrate how to write unit tests

• YYID for Elixir
• YYID for Go
