Name Invisible Secrets
Ontology
Extension(s) .isc,.exe,.locked

Invisible Secrets by East-Tec (formerly NeoByte Solutions) is a Win32 encryption and steganography program that hides data in JPEG, PNG, BMP, HTML and WAV files.

Supports strong encryption (Blowfish, Twofish, RC4, AES, Cast128, GOST, Diamond 2, Sapphire II)

Files can optionally be compressed before encryption or steganography

It can create self-decrypting files

Encrypted files can either be saved in-place or as an .isc file

When 'password-protecting' a program, it encrypts it and renames it with a .locked extension (sample.exe becomes sample.exe.locked), requiring it to be launched from within Invisible Secrets

PNG and JPEG - the hidden data is placed in the comment field of these file image types (which is located at the beginning of the file for JPEG, at the end for PNG)

BMP, DIB and WAV - uses a 1-bit LSB method

HTML - uses spaces / tab (0/1) added at the end of the lines

In Invisible Secrets 2002 3.2, the LSBs of BMP images not used by the hidden data are all set to 1 or 0, which makes it blatantly obvious that something is hiding. This has supposedly been fixed in v4.
