'''Sealed''' by aleph8 (Alejandro García Peláez) is an open-source web-based (javascript) program for hiding text or a file in an image file.<br />
<br />
It supports reading other image formats like [[JPG]] but the output is always [[PNG]]<br />
<br />
Only a single file can be hidden<br />
<br />
There is an optional password<br />
<br />
The three supported methods are:<br />
<br />
* LSB-Seq-Replacement - can then choose RGB order<br />
* MSB-Seq-Replacement (NOT SECURE) - can then choose RGB order<br />
* LSB-Random-Replacement - can then enter optional secret key<br />
** this mode severely limits the amount of data that can be hidden<br />
<br />
<br />
<br />
== Sample files ==<br />
Hiding the text 'fileformats.archiveteam.org' using 'LSB-Random-Replacement' and secret key 'password':<br />
