Thismeans, that after the certificate is revoked or no longer valid(because the date stated in the field “Valid To” of yourcertificate is in the past) signatures will not be possible.Nonetheless, we implemented the function to decrypt messages withprivate keys even with no longer valid certificates. So yourmessages will always be available to you, even with older keys.Formore information visit
X509Tools 2.7
IMPORTANT: This is the last release of X509Tools! We created a newfully functional email client which includes all features ofX509Tools. So please install R2Mail2 from Google Playinstead!X509Tools was created on top of a proof of concept toprovide S/MIME capabilities and X.509 certificate support toAndroid. It supports the decryption of S/MIME encrypted attachments(smime.p7m) and can send encrypted (and signed) emails. Please notethat this is not an email client, the App only decrypts messagesreceived by other mail clients or sends mails over SMTP.X509Toolshas an interface for external email clients - we are lookingforward to integrate this to K9 etc.For more information visit application needs followingpermissions:* Full Internet Access - required to send emails overSMTP* Modify/Delete SD card content - required to access privatekeystore and write logs* Read Email Attachments - required to readsmime.p7m attachments if your are using K9 email client* ReadContacts - required to suggest email addresses from your contactsif sending plain or signedThe application is split into two parts:*The "Certificate Store" allows you to show the system certificateroot store and manage your own personal store. In your personalstore you can import keys (*.p12, *.pfx) and certificate (*.cer,*.crt, *.pem, *,p7s) of contacts you want to send encrypted mailsto.* The "S/MIME" part allows you to decrypt smime messages andsend encrypted emails. Since this is not an email client use yourpreferred one and simply open the smime.p7m attachment to decryptit with X509Tools (the application opens attachment with themime-type "x-pkcs7-mime").To provide this features we recompiledparts of bouncycastles crypto libraries and javamail for android,which lead to size of 1.3 MB.Although the program is fullyfunctional its still in development. So please help us to fixproblems or add new features by sending request/bugreports A log file is written to /sdcard/x509tools/to help us reproduce you issues. If you got decryption error pleasesend us an equivalent encrypted mail (Cert: that we can debug thisissue.
