Using a broken or risky cryptographic algorithm
The use of a broken or risky cryptographic algorithm is an unnecessary risk that may result in the disclosure of sensitive information.
- Confidentiality: The confidentiality of sensitive data may be compromised by the use of a broken or risky cryptographic algorithm.
- Integrity: The integrity of sensitive data may be compromised by the use of a broken or risky cryptographic algorithm.
- Accountability: Any accountability to message content preserved by cryptography may be subject to attack.
- Design: The decision as to what cryptographic algorithm to utilize is generally made at design time.
- Languages: All
- Operating platforms: All
Likelihood of exploit
Medium to High
Avoidance and mitigation
- Design: Use a cryptographic algorithm that is currently considered to be strong by experts in the field.
Since the state of cryptography advances so rapidly, it is common to find algorithms, which previously were considered to be safe, currently considered unsafe. In some cases, things are discovered, or processing speed increases to the degree that the cryptographic algorithm provides little more benefit than the use of no cryptography at all.
EVP_des_ecb(); In Java:
Cipher des=Cipher.getInstance("DES...); des.initEncrypt(key2);
