Securing your emails by encryption is a obvious and yet it is not very common among the general public but also in companies. It is incomprehensible when we know that the vast majority of information transmitted in a professional context is done by email, especially for external exchanges from the company to its customers or suppliers.

Even though most free consumer instant messengers (whatsapp/skype/signal/telegram) offer end-to-end encryption, we continue to use unencrypted email. Even if your email host secures the emails stored on its servers with symmetrical encryption, an email travels from server to server with various security features and remains a very important time online in the recipients' mailboxes that may be corrupted at some point. This gives, in case of mailbox hack, a dramatic situation with sometimes disastrous financial and human consequences.

Why is the world's most important communication channel, email, not encrypted to provide obvious confidentiality to our correspondence ?
Is there no solution ?

There are two major and very old solutions :


PGP means Pretty Good Privacy, better known as PGP, is a cryptographic encryption software, developed and distributed in the United States by Philip Zimmermann in 1991.


S/MIME means Secure/Multipurpose Internet Mail Extensions is a standard for cryptography and digital signing of email encapsulated in the MIME format. It ensures data integrity, authentication, non-repudiation and confidentiality.

Now, without going into technical details, these protocols are not easy to use and understand, nor to set up; it requires getting organized with your correspondents and the slightest change calls into question the communication. If every time you send an email, you have to explain beforehand who is « Alice and Bob » (common names used in cryptography), it's impractical. This is simply the reason why these protocols have not been democratized en masse; however good they may be.

How complicated it is, most of them have given up and we have forgotten that the secrecy of correspondence is a legitimate, obvious right that we no longer even demand. Worse, we have accepted the idea of services consulting them to « improve their product and services and to provide us with personalised offers ». Because even if you are not on this type of service, how many of your correspondents are?

If you want the same level of privacy as PGP / S/MIME for your emails by just clicking on a "Send" button and without asking anything to your correspondents, we designed BlueFiles for this reason.

Like PGP et S/MIME BlueFiles is a globally asymmetric system (end-to-end encryption) which therefore also guarantees confidentiality, authenticity of the sender and recipient simply by clicking on a "Send" button only by filling in his email (whatever his provider) and without having to organize with your correspondents in advance (unlike instant messaging, it's even better).
