  - At least 1 lowercase letter
  - At least 1 digit
  - At least 1 special character
  - No common words or patterns
- **Security**: No backdoors, passphrase required at every boot

#### 2. Mandatory Password Complexity

  - Uppercase (A-Z): Minimum 1
  - Lowercase (a-z): Minimum 1
  - Digits (0-9): Minimum 1
  - Special (!@#$%^&*): Minimum 1
- **Enforcement**: PAM pwquality module
- **Additional Requirements**:
  - At least 4 characters different from previous password
  - Maximum 2 consecutive identical characters
  - Maximum 2 monotonic sequences (e.g., 123, abc)
  - No dictionary words
  - No username in password
- **Enforced For**: All users including root

### Configuration Changes

#### preseed.cfg
- Partition method: `crypto` (LUKS encryption)
- LVM within encrypted partition
- AES-XTS-plain64 cipher, 512-bit key
- LUKS2 format enabled
- Secure disk erasure enabled
- Default password/passphrase: 24-char complex password
- Added packages:
  - cryptsetup
  - cryptsetup-initramfs
  - dmsetup
  - libpam-pwquality

#### New Hooks Created
1. **config/hooks/installed/encryption-setup.sh**
   - Configures LUKS2 settings
   - Sets up initramfs for encryption
   - Creates key management scripts
   - Configures encryption status service

2. **config/hooks/installed/encryption-validation.sh**
   - Validates encryption configuration
   - Creates user reminder files
   - Sets up MOTD encryption messages
   - First boot encryption check service

#### Enhanced Security Hardening
- src/security-hardening.sh updated with stronger password policy
- /etc/security/pwquality.conf configuration:
  - Minimum length: 14 characters
  - Mandatory character classes (upper, lower, digit, special)
  - Additional complexity requirements
  - Bad words blacklisted
  - Enforcement enabled for all users including root

### Documentation Created/Updated

#### AGENTS.md
- Added MANDATORY security requirements section
- Full disk encryption requirements documented
- Password complexity requirements documented
- Compliance references added

#### README.md
- Updated features to highlight encryption
- Mandatory security requirements section
- Clear statement of encryption and password requirements

- Build status and next steps

#### RESUME.md
- Updated with current build status
- Documented new requirements added
- Build progress tracking

### Build Configuration
- Docker container with --privileged flag
- Building in /tmp inside container (not mounted volume)
- Minimal configuration (no problematic flags)
- All operations in Docker (AGENTS.md compliant)
- Output will be copied to output/ directory

2. Check ISO with SHA256 and MD5 checksums
3. Test ISO in virtual machine (libvirt/virsh)
4. Verify encryption setup during installation
5. Test passphrase prompt at boot
6. Verify password complexity enforcement
7. Validate all security requirements
8. Document any issues and fixes
