# TLS 1.3 Configuration Template
|
|
|
|
## Pre-Configuration Checklist
|
|
|
|
- [ ] Verify OpenSSL version >= 1.1.1 (`openssl version`)
|
|
- [ ] Obtain valid TLS certificate from trusted CA
|
|
- [ ] Identify all server endpoints requiring TLS
|
|
- [ ] Determine minimum TLS version (1.2 or 1.3 only)
|
|
- [ ] Plan certificate renewal automation (Let's Encrypt / ACME)
|
|
- [ ] Review compliance requirements (PCI-DSS, HIPAA)
|
|
|
|
## nginx Configuration Template
|
|
|
|
```nginx
|
|
ssl_protocols TLSv1.2 TLSv1.3;
|
|
ssl_ciphers 'ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256';
|
|
ssl_prefer_server_ciphers off;
|
|
ssl_ecdh_curve X25519:secp256r1:secp384r1;
|
|
ssl_session_timeout 1d;
|
|
ssl_session_cache shared:SSL:10m;
|
|
ssl_session_tickets off;
|
|
ssl_stapling on;
|
|
ssl_stapling_verify on;
|
|
add_header Strict-Transport-Security "max-age=63072000; includeSubDomains; preload" always;
|
|
```
|
|
|
|
## Python TLS 1.3 Client Template
|
|
|
|
```python
|
|
import ssl
|
|
import socket
|
|
|
|
context = ssl.SSLContext(ssl.PROTOCOL_TLS_CLIENT)
|
|
context.minimum_version = ssl.TLSVersion.TLSv1_3
|
|
context.load_default_certs()
|
|
|
|
with socket.create_connection(("example.com", 443)) as sock:
|
|
with context.wrap_socket(sock, server_hostname="example.com") as tls:
|
|
print(f"Protocol: {tls.version()}")
|
|
print(f"Cipher: {tls.cipher()}")
|
|
```
|
|
|
|
## Validation Commands
|
|
|
|
```bash
|
|
# Test TLS 1.3 support
|
|
openssl s_client -connect example.com:443 -tls1_3
|
|
|
|
# Show full certificate chain
|
|
openssl s_client -connect example.com:443 -showcerts
|
|
|
|
# List supported cipher suites
|
|
openssl s_client -connect example.com:443 -cipher 'ALL' -tls1_3
|
|
|
|
# Test with testssl.sh
|
|
./testssl.sh --protocols --ciphers --headers example.com
|
|
```
|
|
|
|
## Security Headers Checklist
|
|
|
|
| Header | Value | Purpose |
|
|
