E-mail Security & Encryption

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.
