Puffer is a general purpose 256-bit AES encryption utility for protecting your most sensitive data. Use Puffer to securely exchange email with other Puffer users via the 2048-bit Diffie-Hellman key exchange function. Compress and encrypt your data files into zip-style PUF archives. Use steganography to hide data among the pixels of image files. Distribute self-decrypting archives to non-Puffer users. Permanently erase data with wipe functions.

This is a demo of YUVsoft Watermarking technology (YUV Watermarking) capabilities. The program can watermark typical standard definition videos with a user defined text, making it possible to extract a mark after compression or other typical video processing. Also it can be used for hidden information transmission. In most situations a watermark can not be detected and/or changed by standard steganography methods.

1-2- Free Steganography Invisible Secrets allows you to encrypt and hide files in other files (carriers) which are not suspect of encryption (JPG, PNG, BMP). First, It will encrypt the sensitive data using a specified password and cryptosystem (algorithm). After that, the encrypted data will be inserted in the carrier.

Use steganography and digital watermarking techniques to encrypt / encryption any file in any other file. Often used to hide data / messages in image files / photographs (JPG, BMP etc) , but this software allows you to hide any file type (jpg, bmp, txt, zip, dbf) into any other file type mp3,dbf,zip...practically anything).

Hermetic Stego is a a steganography program which allows you to encrypt and hide a file of any size in one or more BMP image files, with or without the use of a stego/encryption key, so that the presence of the hidden file is undetectable , even by forensic software using statistical methods and 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.

PSM Encryptor is a cryptography and steganography tool. PSM Encryptor will encrypt any group of files (including whole directory structures) but will also disguise the resulting encrypted archive as a working sound or image file. In addition, PSM Encryptor ships with its own video codec: you can encrypt videos which can then be decrypted in real-time as you watch them, with no noticeable loss of performance or quality. Integrated email engine.

Hide and encrypt text in bitmaps using Steganography. Includes Delphi source. Freeware with nice simple interface and detailed description of encoding process.

Secure your data on a virtual encrypted drive. This software created a logical drive, encrypts it and mounts it on your disk system. It looks like you have an extra disk on your computer, but in fact this is an encrypted storage. Then you can move your files on to this disk and be sure that they are securely encrypted. Encryption process is performed in real-time and is automatic.

Invisible Secrets 4 hides your private data into innocent looking files, like pictures, or web pages. It also features: strong encryption algorithms; a locker that allows you to password protect certain applications; a password management solution and a real-random password generator; a shredder that helps you destroy beyond recovery files, folders and internet traces; the ability to create self-decrypting packages; secured password transfer.
