CryptWit - Free email encryption software
CryptWit is designed to resolve two major flaws of email communication.
Email transport is almost always based on plain text, which makes it completely insecure. The other problem is that most email providers block large attachments.
CryptWit makes email more secure by encrypting message body as well as attachments.
How it works? It utilizes digital compression to reduce total size of email message thus allowing more data through limited email communication channels.
CryptWit encrypts message contents as well as attachments. Email encryption prevents electronic mail from being read by an unintended recipient and from being scanned and filtered by software sniffers. Even if it is intercepted or copied, the message will stay encrypted unless the recipient has the key.
CryptWit compresses message contents and attachments. Data compression makes the CryptWit message up to 80% smaller than the original message by using lossless compression algorithms, originally developed by Phil Katz from PKWare and later acquired by IBM. This allows sending more data in one transmission without using large file transfer services.
Anyone can use it
Your recipients do not need CryptWit to read encrypted message. Any email recipient can receive secure communication from CryptWit. To decrypt and read it they'll need a password. No special software is needed on the recipient's computer. In fact, emails sent by CryptWit are delivered via Hotmail, Yahoo, Gmail, and other free email services perfectly.
Portable message format
The complete portability of the message format is what makes CryptWit great. CryptWit archives an email message into a ZIP file and encrypts its contents before sending. Most of the modern computers and mobile devices support ZIP files right out of the box.
CryptWit supports up to 20Mb of file attachments to be sent in a single encrypted ZIP file. If the original message contains more data, it is recommended to split it into multiple submissions, or use a file transfer service such as EmailLargeFile.net. Sometimes there is an advantage in using large file transfer services, as they often provide advanced file handling, detailed tracking, and delivery confirmation.
What is CryptWit?
CryptWit comes as a free add-in for Microsoft Outlook for Windows. Upon the first use, it prompts to enter the new password for email communication. Other configuration settings such as compression level and encryption strength come pre-set to provide optimal performance figures. By default, the password to the archive is never sent to the recipients in the same message, as this would neutralize the security of the email communication. The password should be kept separate from the encrypted message.
The product setup package and the plug-in come digitally signed with secure electronic certificate. If you have acquired the software without the certificate, do not install it.
