Encryption of email messages is a common component of enterprise security and privacy. However, encrypted data poses a challenge for eDiscovery procedures and compliance investigations. When an email message is encrypted, it is not possible to search or index the encrypted portion of the message. Only the unencrypted portion of the message can be searched, such as the subject, sender name, and recipient names.
DecryptNaBox Lite / SecTool is a Windows workstation product that can be used to decrypt (or encrypt) large numbers of email messages. The software is easy to use, and has a simple user interface. DecryptNaBox Lite supports multiple types of email message sources. It can use an Outlook profile as the message source, or a folder hosted locally or on a network drive. When pointing to a folder, the tool will include all files with .PST, .MSG, and .EML formatted files. The tool also has the option to process subfolders located within the referenced folder.
DecryptNaBox Lite provides decryption (or encryption) for email messages that are protected by Secure/Multipurpose Internet Mail Extensions (S/MIME), Pretty Good Privacy (PGP), or Microsoft Right Management Server (RMS). DecryptNaBox Lite is capable of decrypting messages with any of the typical formats such as HTML, Text, and RTF in both MIME and TNEF formats.
DecryptNaBox Lite can be used in different ways depending on an organization’s needs. Some organizations need to decrypt and examine targeted user mailboxes during investigations. Others use DecryptNaBox Lite during ESI collection in support of legal discovery. After inspection, DecryptNaBox Lite can be used to re-encrypt the email messages to ensure privacy is maintained. DecryptNaBox Lite has also been used to support merger and acquisition changes and PKI technology conversions, where mailboxes are decrypted with a legacy encryption technology and re-encrypted with a new technology.

Encryption of email messages is a common component of enterprise security and privacy. However, encrypted data is typically a challenge for eDiscovery procedures, and is often excluded from review. Zeva SecTool provides the means to decrypt, and encrypt, massive amounts of Exchange data quickly and easily.
In the year 2000, Microsoft released a tool as part of the Exchange 2000 resource kit that could encrypt and decrypt large numbers of email messages. This tool was discontinued by Microsoft and was not available for Outlook versions beyond Outlook 2003. No substitute has been available.... that is, until Zeva SecTool.
Zeva created Zeva SecTool to provide the ability to massively decrypt and/or encrypt email messages that are secured using Secure/Multipurpose Internet Mail Extensions (S/MIME). Developed by Zeva engineers, SecTool has proven to be a valuable addition to an organization's IT toolkit. When an email message is encrypted, it is not possible to search or index the encrypted portion of the message. For encrypted messages, the search and indexing capability is limited to the unencrypted portion: subject, sender name, recipient names, etc.
Zeva SecTool can be used in different ways depending on an organization's needs. Some need to decrypt and examine targeted user mailboxes during investigations. Others need to decrypt email messages, index the content of the messages, and then re-encrypt the messages. In some regulated industries, examination of all message content may be necessary to meet compliance goals. Zeva SecTool can be configured to meet all these needs.
In Zeva SecTool V2.0, it is also possible to encrypt/decrypt independent PST files without the need to link them to Outlook.
Zeva stopped support for Sectool and rebranded it as "DecryptNaBox Lite" which is available for download above.
