Crypto50 is user-friendly data encryption softwer build with python. that empowers you to encript and decript sensitive file and text data using a pawerful hybrid encryption aprroach. Crypto50 specially design to securely share your sensitive data through the internet i.e. email, cloud stroage etc. it offers both graphical (GUI) and command-line (CLI) interfaces and adheres to the Model-View-Presenter softwer design pattern.

• Interfaces : GUI and CLI
• Softwer Architectural Pattern : MVP
• Encryption Tecnology : Hybrid Cryptography
• Version : 1.0

1. Clone GitHub repositories :
   • Open Terminal/CMD to a specific directory
   • Install git softwer (if already install skip this step)
   • Run this command : git clone https://github.com/codebysumit/Crypto50.git
2. Change working directory to project directory
   • Run this command : cd Crypto50
3. Install dependencies:
   • Install Python and pip (if already install skip this step)
   • Run this command : pip intall -r requirements.txt

• Open project root directory Crypto50
• Run this command : python test_project.py
• After unit testing some cache file automaticlly generated __testfiles__/testing_module this folder due to testing process (you can delete this folder).

• Open project root directory Crypto50
• Run this command : python project.py

Open project root directory Crypto50 and according to your requirment run flowing command.

1. Generate RSA Private key + Public :

   • Generate RSA keys set : python crypto50.py --generate_key "OUTPUT_FOLDER_PATH"

   • >>> python crypto50.py --generate_key "OUTPUT_FOLDER_PATH"
     Keys successfully save to: OUTPUT_FOLDER_PATH/KEYS_20240307_201805_425722

2. Encryption :

   • Encryption text : python crypto50.py --encryption_text "INPUT_TEXT" --output "OUTPUT_FILE_PATH" --pub_key "RECIVER_PUBLIC_KEY_FILE_PATH" --priv_key "SENDER_PRIVET_KEY_FILE_PATH"

   • >>> python crypto50.py --encryption_text "INPUT_TEXT" --output "OUTPUT_FILE_PATH/ENCRYPTION_FILE_NAME.enc" --pub_key "RECIVER_PUBLIC_KEY_FILE_PATH/public.pem" --priv_key "SENDER_PRIVET_KEY_FILE_PATH/private.pem"
     Encription text successfully save to: OUTPUT_FILE_PATH/ENCRYPTION_FILE_NAME.enc

   • Encryption File : python crypto50.py --encryption_file "INPUT_FILE_PATH" --output "OUTPUT_FILE_PATH" --pub_key "RECIVER_PUBLIC_KEY_FILE_PATH" --priv_key "SENDER_PRIVET_KEY_FILE_PATH"

   • >>> python crypto50.py --encryption_file "INPUT_FILE_PATH/INPUT_FILE.txt" --output "OUTPUT_FILE_PATH/ENCRYPTION_FILE_NAME.enc" --pub_key "RECIVER_PUBLIC_KEY_FILE_PATH/public.pem" --priv_key "SENDER_PRIVET_KEY_FILE_PATH/private.pem"
     Encription file successfully save to: OUTPUT_FILE_PATH/ENCRYPTION_FILE_NAME.enc

   • Encryption Folder : python crypto50.py --encryption_folder "INPUT_FOLDER_PATH" --output_dir "OUTPUT_FOLDER_PATH" --pub_key "RECIVER_PUBLIC_KEY_FILE_PATH" --priv_key "SENDER_PRIVET_KEY_FILE_PATH"

   • >>> python crypto50.py --encryption_folder "INPUT_FOLDER_PATH" --output_dir "OUTPUT_FOLDER_PATH" --pub_key "RECIVER_PUBLIC_KEY_FILE_PATH/public.pem" --priv_key "SENDER_PRIVET_KEY_FILE_PATH/private.pem"
     [1/4] : Successfully encripted "OUTPUT_FOLDER_PATH/INPUT_FILE_1.mp4" ==> "OUTPUT_FOLDER_PATH/ENCRYPTION_1.enc"
     [2/4] : Successfully encripted "OUTPUT_FOLDER_PATH/INPUT_FILE_2.jpg" ==> "OUTPUT_FOLDER_PATH/ENCRYPTION_2.enc"
     [3/4] : Successfully encripted "OUTPUT_FOLDER_PATH/INPUT_FILE_3.mp3" ==> "OUTPUT_FOLDER_PATH/ENCRYPTION_3.enc"
     [4/4] : Successfully encripted "OUTPUT_FOLDER_PATH/INPUT_FILE_4.txt" ==> "OUTPUT_FOLDER_PATH/ENCRYPTION_4.enc"
     Successfully encripted 4 files.

3. Decryption :

   • Decryption File : python crypto50.py --decryption_file "ENCRYPTED_FILES_PATH" --output_dir "OUTPUT_FOLDER_PATH" --priv_key "RECIVER_PRIVET_KEY_FILE_PATH" --pub_key "SENDER_PUBLIC_KEY_FILE_PATH"

   • >>> python crypto50.py --decryption_file "ENCRYPTED_FILES_PATH/ENCRYPTION_FILE_NAME.enc" --output_dir "OUTPUT_FOLDER_PATH" --priv_key "RECIVER_PRIVET_KEY_FILE_PATH/private.pem" --pub_key "SENDER_PUBLIC_KEY_FILE_PATH/public.pem"
     Decription file successfully save to: OUTPUT_FOLDER_PATH/DECRYPT_20240307_212528_345110.txt

   • Decryption Folder : python crypto50.py --decryption_folder "ENCRYPTED_FILES_FOLDER_PATH" --output_dir "OUTPUT_FOLDER_PATH" --priv_key "RECIVER_PRIVET_KEY_FILE_PATH" --pub_key "SENDER_PUBLIC_KEY_FILE_PATH"

   • >>> python crypto50.py --decryption_folder "ENCRYPTED_FILES_FOLDER_PATH" --output_dir "OUTPUT_FOLDER_PATH" --priv_key "RECIVER_PRIVET_KEY_FILE_PATH/private.pem" --pub_key "SENDER_PUBLIC_KEY_FILE_PATH/public.pem"
     
     [1/4] : Successfully decripted "ENCRYPTED_FILES_FOLDER_PATH/ENCRYPTION_1.enc" ==> "OUTPUT_FOLDER_PATH/DECRYPT_20240307_213118_115599.mp4"
     [2/4] : Successfully decripted "ENCRYPTED_FILES_FOLDER_PATH/ENCRYPTION_2.enc" ==> "OUTPUT_FOLDER_PATH/DECRYPT_20240307_213118_386111.jpg"
     [3/4] : Successfully decripted "ENCRYPTED_FILES_FOLDER_PATH/ENCRYPTION_3.enc" ==> "OUTPUT_FOLDER_PATH/DECRYPT_20240307_213118_897642.mp3"
     [4/4] : Successfully decripted "ENCRYPTED_FILES_FOLDER_PATH/ENCRYPTION_4.enc" ==> "OUTPUT_FOLDER_PATH/DECRYPT_20240307_213118_975783.txt"
     Successfully decripted 4 files.
