Cryptographic Implementation

What is Cryptographic Implementation?

Analyses encryption indicators in cookies, tokens, and API responses for weak or deprecated algorithms.

This vulnerability class falls under the Error Handling phase of the OWASP Testing Guide (WSTG-CRYP). Security engineers prioritise error handling checks early in an assessment because weaknesses here provide a foothold that amplifies the severity of vulnerabilities found in later phases.

Security Impact

Weak cryptography can be broken. This module detects MD5, SHA1, and other deprecated algorithms in your implementation.

Left undetected, cryptographic implementation issues can persist unnoticed for months. Continuous automated scanning ensures your team receives an alert the moment a regression or new exposure is introduced — long before an attacker discovers it through manual enumeration or automated offensive tooling.

How DygDog Detects It

DygDog performs TLS/SSL handshakes and cipher negotiation across modern and legacy protocol stacks to identify weak cipher suites, expired certificates, and missing security extensions.

The Cryptographic Implementation check is implemented as a passive scan module, meaning it never sends dangerous payloads or modifies application state. Scans complete in approximately 800 ms and run continuously in the background so your security posture reflects the current state of your site — not a point-in-time snapshot.

Remediation Approach

Disable TLS 1.0 and 1.1, enforce TLS 1.2+ with strong AEAD cipher suites, enable HSTS with a long max-age and includeSubDomains, and automate certificate renewal to prevent expiry gaps.

DygDog does not stop at detection. When a Cryptographic Implementation finding is confirmed, the platform generates infrastructure-aware, copy-paste-ready remediation snippets using frontier AI models. Instead of generic advice you need to adapt, you receive code that targets your exact server, framework, and configuration.

Related Error Handling Checks

These checks belong to the same testing phase and are often assessed together:

• Error Message Analysis

  Detects verbose error messages that disclose stack traces, database queries, or internal paths.

• Business Logic Indicators

  Detects patterns that may enable business logic abuse: price manipulation fields, quantity limits, workflow bypass paths.

• Rate Limiting Detection

  Checks for rate limiting headers (X-RateLimit-*), retry-after responses, and CAPTCHA implementations on sensitive endpoints.

• Exposed Secrets & API Keys

  Scans page source for leaked credentials: AWS keys, API tokens, database connection strings, private keys.
