Do not hard code sensitive data in programs.

See MSC31MSC41-C. Never hard code sensitive information for more informationdetails.

Disable memory dumps.

Memory dumps are automatically created when your program crashes. They can contain information stored in any part of program memory. Therefore, memory dumps should be disabled before an application is shipped to users. See MEM06-C. Ensure that sensitive data is not written out to disk for details.

CERT C: Rec. MSC18-C


Checks for:

  • Constant or predictable block cipher initialization vector
  • Constant or predictable cipher key
Polyspace Bug FinderR2016a
  • Sensitive heap memory not cleared before release
  • Uncleared sensitive data in stack
  • Unsafe standard encryption function

Constant cipher key, predictable cipher key

Constant block cipher initialization vector

Sensitive data not cleared or released by memory routine

Variable in stack is not cleared and contains sensitive data

Function is not reentrant or uses a risky encryption algorithm

Encryption or decryption key is constant instead of randomized or  generated from a weak random number generator

Initialization vector is constant instead of randomized

Rec. partially covered.
