Crypture

Crypture is a modified stenography application that is designed to encrypt files and programs by converting them to the bitmap file format, making them unrecognizable from their original format. The encryption method supports a 1024 bit key encryption when it performs the conversion, making it highly secure. As well as the picture format not being immediately apparent as a text document, making it both digitally and visually encrypted, effectively hiding the file as well as encrypting it.

Once Crypture has converted a file into the bitmap format, it then fills all the blank areas of the bitmap with noise, making it harder to decipher via conventional steganalysis methods. Providing an additional layer of security to the program by avoiding certain decryption methods.

To make files even more secure, Crypture also encrypts the header and the data involved with it, making the file even harder to detect or decrypt. The application includes no decryption method itself, only offering a method to encrypt.

It is possible to encrypt over 10000 characters within a single image, which amounts to little over 300 pages of text.

Crypture is a small file, only 6 KB and doesn't require an installation, there is no help documentation either included.
