Djigzo

Djigzo email encryption gateway is an exceptional email server that encrypts and decrypts both incoming and outgoing emails. It functions like a standard SMTP server, thereby, guaranteeing the compatibility of the already existing email servers with regular email clients. Djigzo is typically installed as a "store and forward" server, with emails being temporarily stored until they are forwarded to their final destination.

With two encryption standards to choose from, Djigzo is an excellent choice for anyone looking to ensure the security of their emails. S/MIME provides authentication, message integrity, and non-repudiation (using X.509 certificates), and protection against message interception. S/MIME utilizes public key encryption (PKI) for encryption and signing.

PDF encryption, on the other hand, is a lightweight option that is an excellent alternative to S/MIME encryption. PDF documents contain attachments embedded within the encrypted PDF, and you can quickly decrypt and read the encrypted PDF. For password protection, the password for the PDF can be manually set per recipient or a password can be randomly generated and sent to the recipient via an SMS Text message.

Djigzo even has its own built-in CA, which allows you to issue X.509 certificates for both internal and external users. It only takes a few quick steps to set up the external user, allowing them to utilize the certificate with any S/MIME capable email client like Outlook, Outlook Express, Lotus Notes, Thunderbird, and even Gmail.

Overall, Djigzo email encryption gateway is an excellent software that ensures secure email communication without the hassle of complicated encryption processes.
