Abstract
Disclosed are various approaches for encrypting documents using mobile devices. A first application receives, from a second application a file and an identifier of a user account. The first application then sends a request for a certificate to a certificate authority and receives a certificate in response. The file is then encrypted using the certificate, and the encrypted file is returned to the second application. The second application can identify the user account as the recipient of a file. Then, the second application can send an encryption request that includes the identifier of the user account and the file to the first application. In response to the request, the second application receives the encrypted file and then provides the encrypted file to the recipient.
