Code Security Integration

BoringSSL Example

// Basic TLS server setup
#include <openssl/ssl.h>

int main() {
  SSL_CTX* ctx = SSL_CTX_new(TLS_server_method());
  SSL_CTX_use_certificate_file(ctx, "server.crt", SSL_FILETYPE_PEM);
  SSL_CTX_use_PrivateKey_file(ctx, "server.key", SSL_FILETYPE_PEM);
  // Secure configuration settings
  SSL_CTX_set_options(ctx, SSL_OP_NO_SSLv3 | SSL_OP_NO_TLSv1_2);
  SSL_CTX_set_cipher_list(ctx, "EECDH+AESGCM:EDH+AESGCM");
}

Tink Example

import tink
from tink import aead
from tink import aead_internal

def encrypt_data(plaintext):
    keyset = tink.KeysetHandle(
        tink.BinaryKeysetReader(open('keyset.json', 'rb')).read())
    aead_primitive = keyset.primitive(aead.Aead)
    ciphertext = aead_primitive.encrypt(
        plaintext, b'associated_data')
    return ciphertext

Best Practices for Developer Security

Input Validation

Always validate and sanitize all user inputs to prevent common injection attacks:

Use regex patterns to restrict input formats
Sanitize HTML/JS using OWASP ESAPI
Validate numeric ranges and string lengths

Secure Authentication

Implement multi-factor authentication using:

TOTP (Time-based One-Time Password)
FIDO2/WebAuthn standards
PBKDF2-HMAC-SHA256 with 100k iterations

Secret Management

Store keys securely using:

Hardware Security Modules (HSMs)
Cloud Key Management Service (KMS)
Environment variables with encryption at rest

Logging Security

Follow security logging guidelines:

Avoid storing PII in logs
Use structured logging formats
Monitor for suspicious patterns
