Snyk Code can help identify weak and outdated cryptographic algorithms, such as MD5, that may be used in legacy applications or generated by AI code assistants. These algorithms pose serious security risks and should be avoided; instead, modern and secure cryptographic practices like Bcrypt, PBKDF2, or Argon2 should be used for tasks like password hashing. Snyk provides a fix analysis and best practices for employing strong algorithms, as well as resources on security best practices for cryptography, to help developers ensure the security of their codebases.
