Encryption does not work

[JonasArnold]

Type .bmp does not work:
The file-type .bmp does not work with DECRYPTION. To encrypt you need to use a .BMP or .TXT file.

[JonasArnold]

The reason is that it must be written in capital letters (.BMP not .bmp).
EDIT: FIXED

[JonasArnold]

Fixed Encryption in Version 1.0.4.
Support for Encryption directly via a .txt file will be added soon.
