Reddit reviews PGP & GPG: Email for the Practical Paranoid

I guess, Posteo is what you looking for.

☑ Anonymised payment

☑ Comprehensive and innovative encryption system

☑ Create your own key pair without giving your private key away instead of someone else making it for you where they also posses the private key (like ProtonMail).

Not only does Posteo look good from looking at:

Their JavaScript source codes are also publicly available. Check also hacker10's review on Posteo.

>Is Gnupg something different?

Edit: Wiki: "GNU Privacy Guard (GnuPG or GPG) is a free software replacement for Symantec's PGP cryptographic software suite..."

Quoting from PGP & GPG: Email for the Practical Paranoid:

>- The word PGP is used only for the PGP Corporation product. If you see the word PGP, it means only that product and not GnuPG or any other implementation of OpenPGP. The PGP folks will be unhappy with you if you call some other product PGP.
>- The words GnuPG and GPG apply specifically to the Gnu Privacy Guard tool. The GnuPG folks will be unhappy with you if you call their product PGP.
>- The word OpenPGP* applies to PGP, GnuPG, and any other implementation of PGP. Yes, there are other implementations of the OpenPGP standard out there. Many vendors incorporate OpenPGP functionality into their products. None are as well known or as accepted as PGP or GnuPG, however. Nobody will be unhappy with you for calling their product OpenPGP compliant.

Relevant: If PGP and GPG both follow the OpenPGP standard, are they 100% compatible in all use cases?
