We recommend a password of more than 8 characters including upper and lower case letters, numbers and special characters ($, &, -, !, %, etc.). Please save your password in an offline location that only you will have access to. You will not be able to retrieve your password if you lose it.

Please click on 'Generate Key' to generate your key pair.

How to encrypt your communications with Windows?

We strongly recommend encryption of your communications in order to guarantee their authenticity, integrity and confidentiality.

First of all, you will have to download the software by following this link.

As the software is linked to a free protocol, you will have the possibility to make a donation. This is not necessary to continue. If you do not wish to make a donation, you can select $0 and click on 'Download'.

Once the software is downloaded, you can start and follow the different steps of the installation. Only 'GnuPG' and 'Kleopatra' are required for our tutorial. The other options are optional.

Once installed, please open Kleopatra and click on 'New Key Pair'. You can select a name and the mailbox linked to your Paymium account.

We recommend a passphrase of more than 8 characters including upper and lower case letters, numbers and special characters ($, &, -, !, %, etc.). Please save your passphrase in an offline location that only you will have access to. You will not be able to retrieve it otherwise.

Files must be sent to this email address, otherwise they cannot be decrypted. Please select the line with the name 'Support Paymium' and the email '[email protected]' (you will find the right address thanks to the fingerprint above).
