Weak Symmetric Algorithm

What does this mean ?

The use of a broken or risky cryptographic algorithm is an unnecessary risk that may result in the exposure of sensitive information. The use of a non-standard algorithm is dangerous because a determined attacker may be able to break the algorithm and compromise whatever data has been protected. Well-known techniques may exist to break the algorithm.

What can happen ?

The confidentiality and integrity of sensitive data may be compromised by the use of a broken or risky cryptographic algorithm. Any accountability to message content preserved by cryptography may be subject to attack.

Recommendation

  • Use a cryptographic algorithm that is currently considered to be strong by experts in the field like AES.
