SecureUpload

This Flask web application allows users to securely encrypt and decrypt files using a passphrase. The encryption key is derived from the user-provided passphrase using PBKDF2 with a random salt, ensuring stronger security.

Users can:

• Upload a file and provide a passphrase to receive an encrypted version of the file.
• Decrypt an encrypted file by providing the same passphrase.

Getting Started

Prerequisites

• Python 3.8+
• pip

SetUp

pip install -r requirements.txt

5. Run the application

python app.py

Once the application is running, open your browser and navigate to: http://127.0.0.1:5000/

Features

• Passphrase-based encryption key derivation using PBKDF2 with SHA-256.
• Random salt generation stored alongside the encrypted data.
• Fully secure as the original files and passphrase is not stored anywhere else.
• Encryption and decryption with Fernet symmetric encryption.
• File upload and download handled securely via Flask's cryptographic library.

Disclaimer

Please remember your passphrase, as it is required to decrypt your file.
