Pure Python desktop GUI application for encrypting files and creating digital signatures

Implementing RSA, AES and SHA256 algorithms with pure python and GUI with Tkinter. Application provides data integrity and confidentiality by encrypting files and signing them with digital signature of a sender.

Encryption scheme

Decryption scheme
