# Performing Hardware Security Module Integration

## Overview

Hardware Security Modules (HSMs) provide tamper-resistant cryptographic key storage and operations. This skill covers integrating with HSMs via the PKCS#11 standard interface using python-pkcs11, performing key generation, signing, encryption, and verification operations, querying token and slot information, and validating HSM configuration for compliance with FIPS 140-2/3 requirements.


## When to Use

- When conducting security assessments that involve performing hardware security module integration
- When following incident response procedures for related security events
- When performing scheduled security testing or auditing activities
- When validating security controls through hands-on testing

## Prerequisites

- HSM device or software HSM (SoftHSM2 for testing)
- PKCS#11 shared library (.so/.dll) for the HSM vendor
- Python 3.9+ with `python-pkcs11`
- Token initialized with SO PIN and user PIN
- For AWS CloudHSM: `cloudhsm-pkcs11` provider configured

## Steps

1. Load PKCS#11 library and enumerate available slots and tokens
2. Open session and authenticate with user PIN
3. Generate RSA 2048-bit or EC P-256 key pairs on the HSM
4. Perform signing and verification using on-device keys
5. List all objects (keys, certificates) stored on the token
6. Query mechanism list to verify supported algorithms
7. Generate compliance report with key inventory and algorithm audit

## Expected Output

- JSON report listing HSM slots, tokens, stored keys, supported mechanisms, and compliance status
- Signing test results with key metadata and algorithm details

# API Reference — Performing Hardware Security Module Integration

## Libraries Used
- **python-pkcs11**: Python PKCS#11 wrapper for HSM cryptographic operations
- **json**: JSON serialization for audit reports

## CLI Interface
```
python agent.py --lib /usr/lib/softhsm/libsofthsm2.so --token MyToken --pin 1234 slots
python agent.py --lib /usr/lib/softhsm/libsofthsm2.so --token MyToken --pin 1234 objects
python agent.py --lib /usr/lib/softhsm/libsofthsm2.so --token MyToken --pin 1234 gen-rsa --label mykey --bits 2048
python agent.py --lib /usr/lib/softhsm/libsofthsm2.so --token MyToken --pin 1234 gen-ec --label myec
python agent.py --lib /usr/lib/softhsm/libsofthsm2.so --token MyToken --pin 1234 sign-verify --key-label mykey
python agent.py --lib /usr/lib/softhsm/libsofthsm2.so --token MyToken --pin 1234 mechanisms
python agent.py --lib /usr/lib/softhsm/libsofthsm2.so --token MyToken --pin 1234 full
```

## Core Functions

### `load_library(lib_path)` — Load PKCS#11 shared library
Calls `pkcs11.lib(lib_path)` to initialize the PKCS#11 provider.

### `enumerate_slots(lib)` — List slots and token info
Iterates `lib.get_slots(token_present=True)`. Returns token label, manufacturer,
model, serial, initialization status, and supported mechanism list.

### `list_objects(lib, token_label, pin)` — Inventory stored keys
Opens authenticated session, calls `session.get_objects()`. Returns object class,
label, key type, key length, and object ID.

### `generate_rsa_keypair(lib, token_label, pin, key_label, bits)` — RSA key generation
Calls `session.generate_keypair(KeyType.RSA, bits, store=True, label=key_label)`.

### `generate_ec_keypair(lib, token_label, pin, key_label)` — EC P-256 key generation
Creates domain parameters for secp256r1 via `encode_named_curve_parameters`,
then calls `ecparams.generate_keypair()`.

### `sign_and_verify(lib, token_label, pin, key_label)` — Signing test
Signs with `priv.sign(data, mechanism=Mechanism.SHA256_RSA_PKCS)`.
Verifies with `pub.verify(data, signature, mechanism=Mechanism.SHA256_RSA_PKCS)`.

### `query_mechanisms(lib, token_label)` — Algorithm support audit
Enumerates all mechanisms with min/max key sizes from the slot.

### `full_audit(lib, token_label, pin)` — Comprehensive compliance report
