In the following example, Mr. Mustermann would like to seal the cooperation on a project with Mr. Doe. To do this, he writes an e-mail that contains project internals such as the description of the project and the access data. Furthermore, Mr. Mustermann adds an attachment with sensitive files. It goes without saying that both parties are interested in ensuring that this e-mail traffic cannot be traced by unauthorized persons. Therefore, this e-mail is encrypted with gpg4o.
By using gpg4o, it is made impossible for a third party to read the e-mail, even if they should manage to intercept it. You as the user are relieved of the work of having to take care of the encryption principle yourself. All you have to do is exchange your public keys with your communication partner once. Once this has been done, you can conveniently select whether the e-mail is to be encrypted and/or signed. The rest is done automatically for you by gpg4o.
