CSHARP.CRYPTO.VALUE : Weak Cryptographic Value (C#)

Summary

Possible generation of weak cryptography values.

Some cryptography algorithms are nowadays considered as outdated and unsafe or actually broken, since they are too easy to decode. This checker identifies uses of unsafe algorithms for cryptography.

Properties

Class Name Weak Cryptographic Value (C#)
Significance security
Mnemonic CSHARP.CRYPTO.VALUE
Categories
CWE CWE:338 Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG)
OWASP-2017 OWASP-2017:A2 Broken authentication
OWASP-2021 OWASP-2021:A2 Cryptographic failures
  OWASP-2021:A7 Identification and authorization failures
OWASP-2025 OWASP-2025:A04 Cryptographic Failures
Availability Available for C# only.
Enabling Checks for this warning class are enabled by default. To disable them, add the following WARNING_FILTER rule to the project configuration file.
