# Seald's documentation
Seald publishes two end-to-end encryption solutions both based on the same technology which has been certified by the ANSSI in 2020 (opens new window):
the solution for developers Seald SDK: allows to integrate end-to-end encryption in an application without any knowledge in cryptography.
Made for developers, it allows end-to-end encryption of files, chat messages, and database fields so that only users can decrypt the data, and at no time can it be read by your servers (nor ours).
the Enterprise solution Seald Desktop App: allows end-to-end encryption of emails and files.
Easy to use, allowing a fine monitoring of each encrypted document or email, allowing third parties not having Seald to encrypt and decrypt without installation.
You will also find a Reference section, containing elements common to Seald solutions, concerning architecture, protocols, etc.
