AttachmentEncryptor solves a big security problem of iOS 7, it can save you from updating to iOS 7.1.2

  Last week I told you that iOS 7including iOS 7.1.1, has a major security problem that completely prevents the encryption of emails sent or received through the system IMAP. Company Apple Lossless Audio CODEC (ALAC), admitted the existence of this vulnerability and promised to fix it through a future iOS update, iOS 7.1.2 being most likely now ready for launch. If you already have jailbreak and you want to solve the problem faster, then the new tweak AttachmentEncryptor can help you.

  Developed by Ryan Petrich, AttachmentEncryptor encrypts the emails sent or received by you through the system IMAP right from the moment of installation, all without making any update to iOS 7.1.2AttachmentEncryptor is currently only available in the repo: http://rpetri.ch/repo/ al Cydia si here you find all its files.
