Hi, if I made this plugin, it's more to learn how to make irshell plugins than to make a real usefull one, but anyway, here is cypher me, it will enbale you to encrypt the highlighted file or decrypt it (when encrypted, if you reencrypt it, then it will decrypt it...).
It's an alpha version, and also my first irs plugin, so don't blame me if you think it is totally useless.
Download it HERE (readme inside)
Or get some more informations go here: MaxTheBest
Hope some will like it...
