The app generates a key during encryption and can store the history of encrypted and decrypted texts.\n\n## Features\n\n- Text encryption using AES algorithm\n- Key generation during encryption\n- Text decryption using the generated key\n- History of encrypted and decrypted texts\n- Works offline\n- Uses `javax.crypto` library\n\n## Screenshots\n\n\u003ctable\u003e\n  \u003ctr\u003e\n    \u003ctd align=\"center\"\u003eHome Screen\u003c/td\u003e\n    \u003ctd align=\"center\"\u003eEncryption\u003c/td\u003e\n    \u003ctd align=\"center\"\u003eDecryption\u003c/td\u003e\n    \u003ctd align=\"center\"\u003eHistory\u003c/td\u003e\n    \u003ctd align=\"center\"\u003eIcon\u003c/td\u003e\n  \u003c/tr\u003e\n  \u003ctr\u003e\n    \u003ctd\u003e\u003cimg src=\"https://github.com/LavKalsi/CryptographyApp/blob/master/Screenshots/Home.jpg\" width=\"150\" height=\"334\"/\u003e\u003c/td\u003e\n    \u003ctd\u003e\u003cimg src=\"https://github.com/LavKalsi/CryptographyApp/blob/master/Screenshots/Encrypt.jpg\" width=\"150\" height=\"334\"/\u003e\u003c/td\u003e\n    \u003ctd\u003e\u003cimg src=\"https://github.com/LavKalsi/CryptographyApp/blob/master/Screenshots/Decrypt.jpg\" width=\"150\" height=\"334\"/\u003e\u003c/td\u003e\n    \u003ctd\u003e\u003cimg src=\"https://github.com/LavKalsi/CryptographyApp/blob/master/Screenshots/History.jpg\" width=\"150\" height=\"334\"/\u003e\u003c/td\u003e\n    \u003ctd\u003e\u003cimg src=\"https://github.com/LavKalsi/CryptographyApp/blob/master/Screenshots/Icon.png\" width=\"120\" height=\"120\"/\u003e\u003c/td\u003e\n  \u003c/tr\u003e\n\u003c/table\u003e\n\n## Installation\n\n1. Clone the repository:\n\n    ```bash\n    git clone https://github.com/yourusername/cryptography-app.git\n    cd cryptography-app\n    ```\n\n2. Open the project in Android Studio.\n\n3. Build and run the project on an Android device or emulator.\n\n    OR\n\n    Go to releases and download the apk file.\n\n## Adding APK to GitHub\n\nTo add the APK file of your app to GitHub, follow these steps:\n\n1. Build your app in Android Studio to generate the APK file. You can find the APK file in the `app/build/outputs/apk/` directory.\n\n2. Create a new release on GitHub:\n    - Go to the \"Releases\" section of your GitHub repository.\n    - Click on \"Draft a new release\".\n    - Fill in the tag version (e.g., `v1.0`) and release title (e.g., `Initial Release`).\n    - Add a description for your release.\n    - Attach the APK file by dragging and dropping it into the release description area or by using the \"Attach binaries by dropping them here or selecting them\" button.\n    - Click on \"Publish release\" to make the release live.\n\n## Usage\n\n1. Open the app on your Android device.\n   \n2. To encrypt text:\n   - Go to the Encrypt section.\n   - Enter the text you want to encrypt.\n   - Press the Encrypt button to generate the encrypted text and key.\n   \n3. To decrypt text:\n   - Go to the Decrypt section.\n   - Enter the encrypted text and the key.\n   - Press the Decrypt button to retrieve the original text.\n   \n4. To view history:\n   - Go to the History section to see the saved history of encrypted and decrypted texts.\n\n## Built With\n\n- [Kotlin](https://kotlinlang.org/) - The programming language used.\n- [javax.crypto](https://docs.oracle.com/javase/8/docs/api/javax/crypto/package-summary.html) - For AES encryption and decryption.\n\n## Contributing\n\nFeel free to contribute to this project by submitting a pull request. Please make sure to follow the standard GitHub flow when contributing.\n\n## Acknowledgments\n\n- Thanks to the creators of the `javax.crypto` library.\n- Inspiration and code snippets from various online resources.\n\n## Author\nLav Kalsi\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Flavkalsi%2Fcryptographyapp","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Flavkalsi%2Fcryptographyapp","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Flavkalsi%2Fcryptographyapp/lists"}
