Key Features

🔐 1. File Encryption (ESX Container)

• Encrypt individual files into a proprietary ESX container
• Supported algorithms:
  • AES-256-GCM (default, authenticated encryption)
  • XChaCha20-Poly1305 (modern, secure, libsodium-based)
  • AES-256-CBC (legacy compatibility)
  • Hybrid RSA+AES (AI-recommended high-security mode)
• Stores:
  • KDF parameters (PBKDF2: iterations, salt, hash algorithm)
  • Integrity hash (SHA-256)
  • Optional user notes
  • RSA components in hybrid mode
• Output files: *.esx

📝 2. Text Encryption

• Encrypt arbitrary UTF‑8 text using the same cryptographic primitives
• Container is Base64-encoded and shown directly in the GUI
• Useful for:
  • Configuration snippets
  • API keys / tokens
  • Short confidential notes

🧠 3. AI Risk Analysis & Smart Encrypt

• Analyses:
  • File extension / type (e.g. *.db, *.zip, *.pem, *.json)
  • Entropy / randomness of content
  • Keywords in the file name (password, wallet, secret, config, …)
• Determines:
  • Risk level: low, medium, high
  • Recommended algorithm: AES-GCM, XChaCha20, or Hybrid RSA+AES
• Displayed in the UI:
  • Detected file type
  • Risk level (incl. score)
  • Recommended algorithm
• Optional toggle “Enable AI Risk Mode”

#️⃣ 4. Hash & Integrity Toolkit

• Hash files and arbitrary text
• Supported algorithms:
  • SHA-256
  • SHA-512
  • SHA3-256
  • SHA3-512
  • BLAKE2b
• Displays hashes as hex strings
• Typical use cases:
  • Integrity checks
  • Post-transfer verification
  • Evidence capturing / forensics

🗑 5. Secure File Shredder

• Securely delete files with 3–7 overwrite passes
• Overwrite strategy per pass:
  • Random data
  • 0x00 pattern
  • 0xFF pattern
• Finally removes the file from the filesystem
• Usage scenarios:
  • Compliance (e.g. GDPR)
  • Destruction of sensitive work files
  • Protection against recovery tools

📊 6. Reports & Export (JSON / TXT)

• The last operation is stored as an internal report
• Export options:
  • report.json – structured, machine-readable
  • report.txt – human-readable, audit-friendly
• Contains, among others:
  • Operation type (e.g. file_encrypt, hash_file, shredder)
  • Paths (input / output)
  • Algorithm
  • KDF parameters
  • AI analysis (score, level, type)
  • Hash information (if applicable)

🌐 7. Multilingual GUI (DE / EN)

• All strings managed via a central TRANSLATIONS mapping
• Switchable via “Deutsch / English” dropdown
• Buttons, labels, groups and dialogs fully translated
• Info dialog with short description, version, and company

---

Technical Architecture

• Language: Python 3.12+
• GUI framework: PySide6 (Qt)
• Cryptography: cryptography library + NaCl/libsodium bindings
• Layout:
  • QScrollArea for compact, scrollable main layout
  • QGroupBox sections for clear functional segmentation
  • Dark mode with visually separated input fields
• Logging:
  • Custom EasySQL class (SQLite)
  • Table operations with timestamp, action, status, message

---

ESX Container Format

The proprietary ESX format includes:

• Magic header + version
• Algorithm ID & flags (e.g. restricted mode)
• KDF parameters:
  • Iterations (PBKDF2)
  • Salt length
  • Hash algorithm (SHA-256 / SHA-512)
• Nonce / IV
• Integrity hash (SHA-256 over the plaintext)
• Optional: RSA-encrypted key material in hybrid mode
• User note (UTF‑8)
• Ciphertext payload

The format is built to be:

• Backwards-compatible across future versions
• Debuggable and extensible
• Structurally parseable for tools and scripts

---

AI Risk Analysis & Smart Encrypt

The AI engine (heuristic, ML-inspired) uses:

• File type (heuristic via extension)
• Entropy (Shannon entropy, normalized)
• Keyword scoring in the filename
• Optional weighting for types like key and database

Result:

• score: 0.0–1.0
• level: low / medium / high
• algo_id: recommended algorithm

Examples:

• Wallet / key files → Hybrid RSA+AES
• Databases / archives → often AES-GCM
• Images / binary files → XChaCha20-Poly1305

---

Hash & Integrity Toolkit

• Choose a file → compute hash → show as hex
• Enter text → compute hash → show as hex
• Last hash is part of the report (hash_info)

Typical use:

• Checksum verification
• Integrity checks when exchanging files
• Security & compliance documentation

---

Secure File Shredder

• Select file → choose number of passes (3–7)
• Multiple overwrites with changing patterns
• Final deletion from the filesystem
• Logging via SQLite including the number of passes

Note: Physical storage characteristics (e.g. SSD wear leveling, caching) can theoretically still affect recoverability, but the approach is significantly more secure than normal deletion.

---

Reports & Logging (EasySQL)

• Every security-relevant operation:
  • Encryption / decryption
  • Hashing
  • Shredder
• Is logged to SQLite (encrypt_studio.db):
  • action, target, status, message, created_at
• Additionally: exportable reports (JSON / TXT)

---

Installation

Requirements

• Windows 10/11 (64-bit)
• Python 3.12.x (or newer)
• Virtual environment recommended

Dependencies (example)

pip install PySide6 cryptography pynacl

The exact dependency set can be managed in a requirements.txt file.

Security & Privacy

• No data is sent to third parties, no cloud connectivity
• No telemetry, no tracking
