Davidson's AES Encryptor

Description

A 256-bit AES encryptor written in Java with GUI built using the Swing framework. You can encrypt and decrypt files up to 150MB.

File Formats

• Encrypted files have a .encrypted extension, and key files have a .key extension.
• Encrypting multiple files is currently not supported. However, you can encrypt a zip folder of these files.

Acknowledgments

• Huge thanks to https://www.samiam.org/ for explaining the AES key-scheduling and mix-columns algorithms in depth. Wikipedia was helpful but this project would have taken countless more hours without this man's help.
• Install4J helped me package the JRE into the executable files for Windows and MacOS.
