MD5 checksums are insecure, and there are tools that may want to consume the index that do not support this hash algorithm. In particular, https://github.com/bouk/arduino-nix is a project which transforms arduino indexes into Nix derivations, however nixpkgs has recently removed support for md5 hashes in derivations. This makes it impossible to consume the Adafruit board index with this tool. This was done systematically using the following script: https://gist.github.com/plietar/301bfcd529d87fd8e091140980b8460f
