The Blog of Juho

This is my blog. Nothing more.

Key material for secure things

This article contains all required information to encrypt a message (before sending to me) and to check a digital signature (signed by me). For people who knows how things work this topic does not require further explanations.

end of TL;DR so now go and read…

If you don’t understand how these things work do not try to encrypt or check anything. You will certainly end up having only a false feeling that your message got encrypted correctly and securely and that way even my mother can (and will) read your “encrypted” message and starts to spread the rumour everywhere.
