I came across a tool written in GO that makes sharing files easy and fast. The tool establish P2P connection and end2end encryption.
Key fetures:
allows any two computers to transfer data (using a relay)
provides end-to-end encryption (using PAKE)
enables easy cross-platform transfers (Windows, Linux, Mac)
allows multiple file transfers
allows resuming transfers that are interrupted
does not require a server or port forwarding

Install: curl https://getcroc.schollz.com | bash
Usage:
To send a file, simply do:

$ croc send [file(s)-or-folder]
Sending ‘file-or-folder’ (X MB)
Code is: code-phrase

To recieve the file on another computre:
croc code-phrase
Easy as that! The tool has other options like using own relay server, change the default ports, use proxy, change encryption curve etc. Visit github repo
for more details.
