Infomaniak kPaste is a free service that enables you to share passwords and sensitive data in total security. This guide explains how kPaste secures your data.

How does kPaste secure your texts?

Infomaniak kPaste encrypts your data directly in the browser using the AES-256 protocol, and more specifically the Galois/Counter Mode (GCM) algorithm. kPaste servers are exclusively based in Switzerland and managed by Infomaniak. They have no knowledge of the texts copied because the data are only transferred and stored on the kPaste servers in encrypted format. Moreover, the kPaste source code is open (view on GitHub), which enables everybody to validate the security and transparency of the service.

For absolute security, we recommend you use kPaste for private browsing by disabling the extensions of your Internet browser.
