 Related weaknesses  include CWE-327: Broken or Risky Crypto Algorithm, and CWE-331 Insufficient Entropy.
 
 Most of the concerns around cytography amount to data being inadvertently being sent in cleartext, sensitive data, the use of old, weak or custom cryptographic algorithms or protocols that are ineffective against attacker efforts to uncover keys,  .  Best practics is to never build your own crypto mechanisms.  Use proven and secure methods like the following:
--Secure Hashes:  SHA-1 has been deprecated as of 2011 with a transition plan released in 2022.  Recommenation to move towards orther families SHA256

 Follow NIST Recommendations for configuring the most secure algorithms when building your applications and securing secrets and data.

-The less an attacker can learn about your system or application, the more difficult (though, of course, not impossible given time and resources) it will be to identify vulnerablilities and craft exploits that could result in a successful compromise.

 Taking every opportunity to add a layer of difficulty (see defense in depth section in Module 3) for malicious actors is one aspect of securing data and applications.
