Image Lock PEA - Encryption of Pictures, Fotos, Images
Image Lock PEA protects photos, drawings, and documents with a password. Thanks to the integrated viewer the images are
never stored unencrypted on the hard disk, but are held only in the memory.
Because all documents can be easily converted in image formats like png, bmp, gif or jpg, the Image Lock PEA is also suitable to display all sorts of documents with a little more effort. You can use for example the PeaFactory's extra menu to convert pdf files into images which can than be encrypted with the Image Lock PEA.
Image Lock PEA uses functions to derive the key from the password, that protect against attackers with a high budget
(availability of ASICs, FPGAs).
The authenticated Encryption (EAX mode) ensures the integrity and authenticity in addition to confidentiality.
The Image Lock PEA offers the possibility to export the encrypted images unencrypted. Different images can be managed by one PEA and can be encrypted with different passwords.
Since version 1.0 you can encrypt several images, but for performance reasons, Image Lock PEA is still not suitable for managing a large number of images.
While for some people encryption is generally associated with "terrorism", the obvious association with encrypted images is probably (child) pornography. It can not be excluded that the Image Lock PEA is also used for such purposes. But to renounce the encryption of all images is neither realistic nor a sensible approach. Patriarchal structures can not be solved with technology (or their renunciation).

How to use
Start the Jar Archive
You need OpenJDK, Java Runtime Environment (JRE) or something similar. On most systems there is at least one available.
These PEAs are single Java jar archives, a file with the extension "jar". If you are familiar with jar archives, you can skip the following part.
java -jar YOUR_ARCHIVE.jaror try to double click the file windows_start.bat
Initialization: First Start
The first time you start the Image Lock PEA, the program will initialize. You are asked for a password and an image file or a directory that contains image files. You can reset the password later in the menu.
Image Lock PEA is part of the PeaFactory, a program to produce password encrypting archives for several purposes.
Like the Image Lock PEA PeaFactory is open source and is available at the PeaFactory Website. With PeaFactory you can create Image Lock PEAs with much more cryptographic algorithms, Image Lock PEAs with a key file property and also PEAs for file and folder encryption or encrypted notes.
You can also use the extra menu of the PeaFactory to convert pdf files into suitable image files which can be encrypted with the Image Lock PEA.
Thanks to all who have improved, tested or reviewed Image Lock PEA or other PEAs.
