Sifrañ PGP

PGP is a tool allowing e-mail encryption and signature.

• Encrypting a message ensures the sender that only the recipients will be able to decrypt and thus read the message.
• Signing a message ensures the identity of the sender to the recipients.

PGP is the abbreviation of Pretty Good Privacy.

postel.bzh proposes a server-side PGP integration as a trusted third party.

The PGP integration in postel.bzh has the following characteristics:

• native webmail integration
• sending and receiving PGP e-mail
• management of the signature and the encryption of e-mails
• operation independent of the client, allowing an equivalent usage on all devices
• generation of private/public PGP key pairs
• import/export of PGP keys generated on postel.bzh or with other tools

As a trusted third party, postel.bzh commits to ensure a maximal security to the users' PGP keys.

Users who wish to use PGP without a trusted third party need to install a mail software with cryptographic capabilities on each device used to access the encrypted e-mails.
