How To Encrypt E-Mails Yourself: PGP Simply Explained


Highly sensitive information is sent every day via e-mail, usually unencrypted. "Pretty Good Privacy" (PGP) promises tap-proof communication for everyone. We explain how to use the technology to securely encrypt your emails.
PGP stands for "Pretty Good Privacy" and is an encryption method developed by Phil Zimmermann in 1991. This ensures that a message can only be decrypted and read by the intended recipient.
PGP was initially not allowed to be exported license-free from the USA because the software fell under the weapons law. To circumvent these restrictions, the source text was published as a book in 1995. After the software was bought up later and the source code was changed and kept under lock and key, the open-source OpenPGP standard was created. The free implementation GnuPG is available as gpg4win for Windows users.

Encrypt mails with gpg4win
Encrypting emails works directly in Outlook. Encrypting emails is not just about protecting privacy. Bank details and passwords should never fall into the wrong hands. You can integrate OpenPGP encryption directly into your mail client or encrypt texts and data manually.
OpenPGP has not yet established itself in everyday life because the effort involved is relatively high. In many companies, however, encrypted mail traffic is standard.
If you want to send your mails with OpenPGP encryption, gpg4win comes with a plug-in for Outlook. Cleopatra is also included in the tool collection. You can use it to encrypt and decrypt data. You can use the notepad to encode messages and then copy and paste them via any chat service. The basis for use is the creation of your own PGP key. Some e-mail providers, such as Tutanota , have their own encryption directly integrated as an alternative to OpenPGP. In this way, you can communicate securely in everyday life without having to forego convenience. The technology is based on the same open source standards. You only have full control if you encrypt your data locally on your PC instead of storing the key on your mail provider's servers.
Practical: OpenPGP not only ensures that data cannot be read by third parties. Signed messages also confirm the identity of the sender. Incidentally, a message can also be encrypted for several recipients at the same time.
