E-mail Security & Encryption

BCArchive enables you to protect your confidential files by adding them to a secure, password protected container. To access the files, all you have to do is enter the archive password and open it to view or edit the files. You can also create a self-extracting version, that allows you to send secure archives by email, that can be opened with the proper password, but do not require BCArchive to be installed on the PC. The program supports strong symmetric encryption algorithms such as Blowfish, IDEA, Triple-DES, CAST5 as well as secure hash algorithms (SHA-1, MD5, RIPEMD-160) and asymmetric (public/secret key) algorithms. Additional features include Windows Explorer integration, send by email, public key manager and more.

Cryptainer LE enables you to create a secure container on your PC, using powerful 128 bit strong encryption - without changing the way you work. The software creates new virtual drive letter(s), and all files that are added to this drive are encrypted on-the-fly. You can also create a secure storage container on any media including external and removable drives (e.g. USB drives, CD etc). The drive letter is accessible through Windows Explorer just like any other drive - as long as you are logged into the Cryptainer PE interface. If the program is terminated, the files in the secure drive are no longer accessible to other users - you can access them at any time by logging in with your password. Using this method, you can automatically keep a secure area, that can only be accessed by you, without having to encrypt individual files manually - just login once. In addition, Cryptainer LE allows you to send files with encrypted email messages, using self-decrypting EXE attachments that do not require any software to be installed by the recipient. The free version is limited to a container size of 25 mb, however you can create an unlimited number of such 25 mb containers.

Crypto Anywhere is a secure, portable email client that is small enough to fit on a single floppy or USB key chain drive. It allows you to send secure email messages from anywhere, without the need to install any software. You can decrypt and encrypt messages using PGP, OpenPGP, SecExMail and others. The program also offers the choice of self-decrypting messages (receiver only needs the password) or public key encryption (receiver needs decryption software). Crypto Anywhere implements strong encryption algorithms based on RSA public key encryption, the Twofish block cipher and the ISAAC random number generator. Additional features include support for attachments, secure friends list (stored keys), message decryption and more. Crypto Anywhere is easy to use and free for personal use. Commercial version requires registration.

ClipSecure is a simple, secure text encryption utility that uses the Windows clipboard, and therefore can be used with any text-based program like email clients, word processors etc. It uses the AES (Rijndael), Blowfish, Cast256, Mars, RC6, Serpent and Twofish encryption standard to provide maximum security! You can encrypt and decrypt text using a keyboard hotkey, or manually from the tray icon. The program encrypts and decrypts fully automatic, there is no need to highlight the text first or to copy it to the clipboard. Extremely simple to use, yet highly secure!

iOpus Secure Email Attachments(SEA) allows you to create secure email attachments that can be opened by the recipient without the need to install any software. The program creates self-decrypting EXE attachments, that can contain one or more files and protects them with a password. All the recipient has to do, is enter the correct passwords, and the protected files will be extracted. The program compresses the files, adding the additional benefit of creating not only secure, but also smaller attachments. SEA is very easy to use, and offers a simple ste-by-step wizard to select the files and create the protected archive. It integrates with the Explorer right-click menu allowing you to quickly create attachments from anywhere within Windows. In addition, the program even allows you to include a custom message text, disclaimer, web site link and a company logo to personalize the decryption screen. iOpus SEA uses the highly secure Blowfish encryption algorithm with a key length of up to 448 bits.
