Secure Vault

Secure Vault is a robust application designed to securely store and manage sensitive files in an encrypted vault. The vault ensures strong protection against unauthorized access, even if the underlying storage medium is compromised.

Features

Core Functionalities

• Vault Creation: Users can create a secure vault protected by a password.
• File Management:
  • Add files to the vault with automatic encryption.
  • View a list of stored files (metadata only).
  • Remove or extract files with decryption.
• Vault Locking and Unlocking: Lock the vault to prevent unauthorized access and unlock it with the correct password.
• File and Vault Integrity Checking: Detect tampering using SHA-256 hashes.

Security Highlights

• Strong Encryption: AES-256 in CTR mode for encrypting file content.
• Secure Key Derivation: Argon2 is used for deriving encryption keys from user passwords with a random salt.
• Data Integrity: SHA-256 ensures file and vault integrity.
• Password Security: Passwords are never stored.

Vault Structure

The vault file consists of:

1. Vault Metadata: Vault-specific details like creation time and salt.
2. File Metadata [Encrypted]: Details about stored files, such as names, offsets, and hashes.
3. Files [Encrypted]: File content stored in a contiguous encrypted format.
4. Integrity Hash: A SHA-256 hash of the entire vault to ensure its integrity.
