Simplify your Android email encryption experience
CipherMail for Android is an Android application which can be used with your existing Android mail application to send and receive S/MIME digitally signed and encrypted email with an Android smartphone.
CipherMail for Android does not provide functionality to retrieve email. An existing Android email application with attachment support, for example Gmail or K9, should be used to retrieve the encrypted attached smime.p7m message.
Ciphermail for Android used to be capable of using a Gmail account for sending email. It lost this capability when Gmail changed its policies and required the use of Oauth to send email via a Gmail account. From version 3.1, Ciphermail for Android will support the use of Gmail with Oauth. Click here for details.
