Military strong 1344 Bit encryption:

DRIVECRYPT securely and easily protects all proprietary data on notebooks and desktop computers 100% of the
time without users having to think about security. Any organization, from a small company to a large international
firm
with thousands of users in the field, can effectively protect business plans, client lists, product specifications,
confidential corporate memos, stock information, and much more with this product.
As data is read from the hard disk, DRIVECRYPT automatically decrypts the data before it is loaded into memory.
When data is written back to the hard disk, it is automatically re-encrypted. The encryption/ decryption process is
completely transparent to the user or any application program -the data is caught "on the fly" as it transfers back
and forth between the hard disk and memory. Consequently, users don't need to remember to decrypt or re-encrypt
their data, or change the normal operation of the PC. In addition, only individual files are decrypted at any one time, not the whole hard disk.

X-EXE is an easy-to-use, but powerful program for encrypting and protecting your data. With X-EXE, you can encrypt files of any type using secure RC6 algorithm. Your self-extracting encrypted files can be viewed on any Windows PC without needing to install any special software. Besides, X-EXE supports steganography, thus allowing you to use digital data hiding technology to encrypt and hide files within other files (carriers) such as pictures or audio files. Carrier files are not damaged after they are used to hide secret information.

The PSM Decryptor is freeware. It is an entirely graphical utility that sits on your desktop (if you want it too) and decrypts archive. Just drag&drop encrypted archives or keys to the Decryptor box and let go... PSM Decryptor does not encrypt. It is a convenient, fast and gorgeous alternative to using the PSM Encryptor demo or full version to decrypt. If you have the demo version or the full version, just ask your contacts to download PSM Decryptor freeware and send them the keys you want them to have. Right-Click on the decryption box if you need help. That's about as complicated as it gets. PSM Decryptor does not contain advertising, it is 100% spyware free. No data is collected. You don't even need to register or give us an email address to download and use it.

Hermetic Stego allows you to encrypt and hide a message (the contents of a computer file) in another file so that the addition of the message to the container file will not noticeably change the appearance of that file. If the file which has been hidden is deleted then there is no indication that it even exists, but it can still be recovered when you need to get at it.

This program allows hiding a file of any size in one or more BMP image files, with or without the use of a user-specified stego key, so that (i) the presence of the hidden file is undetectable (even by forensic software using statistical methods) and (ii) if a user-specified stego key is used then the hidden file can be extracted only by someone, using this software, who knows that stego key.

Later versions of most web browsers will display BMP image files, so it is possible to conceal information within a picture on a web page.

Hermetic Stego allows two operations: (i) hiding a message file in single BMP image file or in a set of BMP images and (ii) extracting a message file from a single BMP image file or a set of them.

This program differs from others of this sort in two respects:

1. There is no limit on the size of the file to be hidden because Hermetic Stego can hide a message file, not just in a single BMP image file, but in a set of them -- as many images as needed to contain the message file.

2. The bits of the message are inserted into the bytes of the image files randomly and in such a way as to defeat the use of statistical tests to reveal the presence of a hidden message.

3. The program can be used with a user-specified stego key or with a default stego key; use of a default stego key allows sending a hidden message to another person who does not know what that stego key is.

The stego key (user-specified or default) is used not only to facilitate random selection of bytes for hiding message file bits but also is used to encrypt the message file.

Steganography: an excellent method of embedding information on the contents of the file within another file! Make your secrets invisible in just 3 quick steps!

Steganography enables you to use digital data hiding techniques (steganography) to hide files and messages within other files (carriers) such as picture or sound files. This allows you to encrypt sensitive information, while at the same time hiding it in a file that will not look suspicious, so nobody even knows that there is any encrypted information.

This program is easy enough for beginners to use.

DriveCrypt Plus Pack (DCPP) is a Full disk encryption software package which encrypts the operating system, and allows pre-boot authentication. The user can enter a password on computer start up, before the operating system boots up. DCPP is the only software on the market abel to hide the entire operating system inside another operating system. This is especially usefull if you are forced to reveal the password to an attacker. In this case he will only see prelared data. DCPP is the fastest and most feature-rich real-time encryption system available, Special care has been taken to render all cryptographic parts as invisible & transparent as possible. DriveCrypt Plus Pack provides true real-time "on the fly" 256-bit disk encryption. Providing advanced FDE (Full disk encryption) as opposed to VDE (Virtual disk encryption) or "container" encryption. DCPP allows you to secure your disk(s) (including removable media) with a powerful and proven encryption algorithm (AES-256) at the sector level, ensuring that only authorized users may access it. The encryption algorithm used by DCPP is a trusted, validated algorithm chosen by the National Institute of Standards and Technology (NIST) and slated to be the cryptographic standard for years to come. AES-256 is a FIPS-approved symmetric encryption algorithm that may be used by U.S. Government organizations (and others) to protect sensitive information. DCPP is automatic and completely transparent to the user. Not only does this decrease user involvement and training requirements, but also it creates the foundation for enforceable security. The careful integration of boot protection and automatic encryption provides a high degree of security with minimal impact on users. Boot protection prevents subversion of the operating system (via floppy boot-up, for example) or the introduction of rogue programs while sector by sector encryption makes it impossible to copy individual files for brute force attacks.

Free program for hiding information in video. Data that you hide can be recovered even from compressed video, or if the video was compressed again by another codec! We smartly change video with understanding how codecs works, introducing small amounts of noise. You can hide not so big files, but for cipher communication or video secret marking it is enough! You can manage redundancy of information in film - if you want to compress video with low bitrate, you should increase redundancy, and vice versa.
