ImageEncryptor is a program allowing user to hide different types of data (just strings for now) inside pictures, encrypting them with a user-defined key.
Use the most recent release to install ImageEncryptor.
Make sure at least .NET Core 3.1 is installed
dotnet version- Find a picture, or create one. Depending on amounts of data you want to encrypt, you'll need different resolutions. Keep in mind, to have the best result, Width mod 3 should equal 0. For example, 99x99 picture can fit 200+ letters.
- Open the program. Enter
1. Enter the path to the picture. - Define a password or leave it empty. 4.1 Read warnings if there are any. Press ENTER to acknowledge every warning. 4.2 Define content to hide in a picture. It may be any text with any characters.
- If there were no errors, output will be in
new.bmp
- Open the program. Enter
2. Enter the path to the picture or the file. - Enter password if there was any. Else, leave it empty.
- Hidden contents of the file should appear.

System.Security.Cryptography.CryptographicException: 'Specified key is a known weak key for 'TripleDES' and cannot be used.' - Please, use a password that is not a common password for hackers to prevent losing security factor of hiding data inside pictures.
[!!!] Encrypted image content WILL differ from old image. Press ENTER to acknowledge. - Not an error, but a warning. It means, that W % 4 == 0. Unfortunately, due to algorithm that we use to hide data inside pictures, we have to extend your picture 1 pixel to the right if W % 4 == 0.
[!!!] Text to encode is too big to fit inside an image. Program will be stopped. - Decrease text length and increase picture width. Make sure width % 3 equals 0, as it gets the best results.
[---] Couldn't confirm the password. - Wrong password. Try leaving it empty, or recheck if password is correct.
Q: I've accidentally forgot the password for a picture! How do I retrieve my data?
A: You can't. We use TripleDES to encrypt contents before hiding them
Q: Does picture quality decrease after encrypting?
A: No, the only quality loss is you can't have transparency in your pictures.
Q: Program doesnt seem to run properly/doesn't start at all!
A: Make sure that you have both .NET Core 3.1 and .NET Framework
Q: Do you support Windows XP/2000/98/95?
A: No
