CipherMail can be used to send and receive S/MIME signed and encrypted email
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.
Features:
- S/MIME 3.1 (X.509, RFC 3280), email encryption and digital signing
- Can be used with the Android Gmail application
- Compatible with existing S/MIME clients (like Outlook, Thunderbird etc.)
- Message and attachments are encrypted
- HTML email support
- Certificates are automatically extracted
- CRLs supported (LDAP and HTTP)
- Certificate trust lists (CTLs) for black/white listing certificates
- LDAP servers can be searched for certificates
- Can generate self-signed certificates for a 'private-PKI'
Notes:
- CipherMail for Android does not provide functionality to retrieve email. An existing Android mail application, for example Gmail, K9 or the default Android email client, should be used to retrieve the encrypted attached smime.p7m message.
- Clear signed digitally signed message can only be verified by opening the message as an .eml file from a file. The complete message is required for validation. Existing mail clients however do not provide access to the complete message.
- If you are using O365, please make sure that SMTP is enabled.
Permissions:
The Contacts permission is required to lookup the recipients for the compose page. If the Contacts permission is not granted, the application will function correctly but recipients cannot be looked-up.
