+# Weak Cryptography
+
+## Description
+Weak cryptography vulnerabilities occur when applications use outdated, weak, or improperly implemented cryptographic algorithms and protocols. This can lead to data exposure, man-in-the-middle attacks, and other security breaches.
+
+## Common Issues
+- Use of weak hashing algorithms (MD5, SHA1)
+- Weak encryption algorithms (DES, RC4)
+- Hardcoded cryptographic keys
+- Insufficient key lengths
+- Improper SSL/TLS configuration
+- Predictable random number generation
+
+## Testing Approach
+Identify cryptographic implementations and test for weak algorithms, hardcoded secrets, and improper configurations.
+
+## Payloads
+See `weak-crypto-payloads.txt` for a comprehensive list of weak cryptography indicators and test cases.
