Package ‘openssl-1.0.2u’ in /nix/store/jj1qwmsil5dj4m3kc95jp5ljyvf86cac-nixos-20.03.1445.95b9c99f6d0/nixos/pkgs/development/libraries/openssl/default.nix:132 is marked as insecure, refusing to evaluate.


Known issues:
 - Support for OpenSSL 1.0.2 ended with 2019.

You can install it anyway by whitelisting this package, using the
following methods:

a) for `nixos-rebuild` you can add ‘openssl-1.0.2u’ to
   `nixpkgs.config.permittedInsecurePackages` in the configuration.nix,
   like so:

     {
       nixpkgs.config.permittedInsecurePackages = [
         "openssl-1.0.2u"
       ];
     }

b) For `nix-env`, `nix-build`, `nix-shell` or any other Nix command you can add
‘openssl-1.0.2u’ to `permittedInsecurePackages` in
~/.config/nixpkgs/config.nix, like so:

     {
       permittedInsecurePackages = [
         "openssl-1.0.2u"
       ];
     }
