A problem, I find, with encrypting one’s emails, is that it works only if sent to people who can decrypt them. And not everybody even knows about encrypted emails.

—–BEGIN PGP SIGNED MESSAGE—–
Hash: SHA512

~~~~~~

You can verify this text for authenticity by original signer.

Encryption techniques are nice, but not easy.
Microsoft also makes many mistakes in the digital signing of their
messages;

Who oh who cares?
I do.

—–END PGP SIGNATURE—–

OscarCP y’re welcome:
In the message is everything beginning from —–BEGIN PGP   to  —–END PGP SIGNATURE—–   is the with PGP signed message.  The actual message is in the middle between the tilde-lines that I started and ended the message with, just to make it a bit more readable:

~~~~~~
…..
…..
~~~~~~

So and thus,  if there is a single letter and/or space within the mesage altered  than this message does not check out to be with a good signature and thus not to be original, like the picture of the pgp-check shows that this case is original.

My original text was signed with my PGPkey. This key consists of two parts: a private part and a public part. The private part of the this key is very secret and only in my possession, and the public part can be sent to somebody else, or to a (public-key) server on the internet, this usually is called a PGP-publickey-server.
Everybody who has anough of my cridentials can collect/download this publickey. Knowing the PGP-ID of somebody is anough to collect this publickey, in this case my “PGP-ID=(0x0DF12480)”.
((to make it a bit more complicated: anybody having the fingerprint of my PGPkey can collect this publickey too; in this case this accompanying fingerprint is “970A 5D81 27BD 73F9 5EB4 4139 B639 39E3 0DF1 2480”.  So when I hand over to somebody this PGP-ID or this PGPkey-fingerprint he can collect my publicPGPkey and can check this text to be original or not. 

But never ever forget:
This whole system of encryption is based on a single trust of  WHO keeps the PrivateKey , that is very easyly forgotten.

This message was only encrypted to my PGPkey, so the result is clearly visible.
When I encrypt this message to an other publickey from somebody else, than this message can only be decrypted by the owner of the other privatekey(s), and now the result is very scrambled with various signs.

herewith the example of the oversight of my PGPkeypair:

((for obvious reasons I blancked-out a few parts))

Using Protonmail or anything like it is based on this “simple principle”, and is a bit more user-friendly    😀

Quote: “ProtonMail – like most email clients that offer PGP – hides all of the complexity of the encryption and decryption of the message. If you are communicating to users outside of ProtonMail, you need to send them your public key first. “

Using Protonmail in a good and smooth way, it’s always best that the receiving party is using Protonmail too, and than all the encryption behind the surface is done automaticly correct.
Using Thunderbird and mobilephone-email with Encryption-keys is very well possible, but not always that smoothly. The internet ‘tends to be very flexible’, as Microsoft learns us all day round with their updates.

ps: There are much more encrypted-email-services, but remember:  WHO keeps the PrivateKeys, and in what jurisdiction?.

pps: Who has nothing to hide, who cares?

The text in this quoted internet link is not quite true, about the part of being unbrakeable encryption. For that there is much more to be done to give the NSA or the x-Eyes-Aliance a hard time to break it.
Ofcourse Quantum-computing is expected to bring this type of encrypting to an end, eventually new techniques must be invented; or is that already there?
