### **DDD Layer Responsibilities**
#### **1. Domain Layer (Crypto) - Business Logic Core**
- **Purpose**: Pure cryptographic computations and algorithms
- **Contains**: FIPS-approved algorithms (AES, SHA, RSA, ECC)
- **Rules**: No external dependencies, no I/O operations, pure business logic
- **Files**: `aes.c`, `sha256.c`, `rsa.c`, `ec.c`
#### **2. Application Layer (SSL/TLS) - Use Case Orchestration**
- **Purpose**: Orchestrates domain objects to fulfill business requirements
- **Contains**: TLS/SSL protocol state machines, certificate validation
- **Rules**: Thin layer coordinating domain objects, no crypto implementation
- **Files**: `tls1_3.c`, `handshake.c`, `record.c`, `verify.c`
#### **3. Infrastructure Layer (Providers) - External Concerns**
- **Purpose**: Handles external dependencies and FIPS compliance
- **Contains**: FIPS module implementation, HSM/TPM integration
- **Rules**: Implements domain/application interfaces, no business logic
- **Files**: `fips_provider.c`, `hsm_provider.c`, `tpm_provider.c`
#### **4. Presentation Layer (Apps) - User Interface**
- **Purpose**: Translates external requests to application calls
- **Contains**: CLI commands, API boundaries, input validation
- **Rules**: Thin layer, no business logic, input validation only
- **Files**: `openssl_cli.c`, `openssl_api.c`
