Sealed
From Just Solve the File Format Problem
Sealed by aleph8 (Alejandro García Peláez) is an open-source web-based (javascript) program for hiding text or a file in an image file.
It supports reading other image formats like JPG but the output is always PNG
Only a single file can be hidden
There is an optional password
The three supported methods are:
- LSB-Seq-Replacement - can then choose RGB order
- MSB-Seq-Replacement (NOT SECURE) - can then choose RGB order
- LSB-Random-Replacement - can then enter optional secret key
