This is an encrypted text and is most prob a url....pls decode it or tell me which cipher is it, this is not for any security breaches and it is a hint in a cryptic hunt

  • What makes you think anything in that URL is encrypted? Could just be a unique identifier. Does not seem long enough to be an encrypted anything.

    @JohnWu: The khgpf:// instead of https:// as protocol at the beginning is a hint that this is not a plain URL. Nov 10, 2020 at 19:17

Looks like a substitution or byte adding/subtracting cipher, you can try to divine it by using logic.

khgpd:// does most likely convert to https:// and .nrf/ does most likely convert to .org, .net, .com, etc while .tue likely matches .htm, .php, .txt, etc.

However the source of the string would also have the necessary code to encode or decode it, so that is probably a faster solution to solving this. There are other ways such as running the code in a controlled lab and observing the network traffic, but this is a trickier thing to do safely, especially if the string comes from some for of malicious code.
