Cryptographically Secure Random vs Non-Cryptographic Random
Developers should use cryptographically secure random when generating data for security-sensitive operations, such as creating encryption keys, session tokens, passwords, nonces, or initialization vectors in cryptographic systems meets developers should use non-cryptographic random when performance and deterministic behavior are critical, such as in scientific simulations, machine learning for data shuffling, or game development for procedural content generation. Here's our take.
Cryptographically Secure Random
Developers should use cryptographically secure random when generating data for security-sensitive operations, such as creating encryption keys, session tokens, passwords, nonces, or initialization vectors in cryptographic systems
Cryptographically Secure Random
Nice PickDevelopers should use cryptographically secure random when generating data for security-sensitive operations, such as creating encryption keys, session tokens, passwords, nonces, or initialization vectors in cryptographic systems
Pros
- +It is essential in applications like web security (e
- +Related to: encryption, cryptography
Cons
- -Specific tradeoffs depend on your use case
Non-Cryptographic Random
Developers should use non-cryptographic random when performance and deterministic behavior are critical, such as in scientific simulations, machine learning for data shuffling, or game development for procedural content generation
Pros
- +It is unsuitable for security contexts like generating encryption keys, tokens, or passwords, where cryptographic random methods are required to prevent predictability and ensure safety
- +Related to: random-number-generation, cryptographic-random
Cons
- -Specific tradeoffs depend on your use case
The Verdict
Use Cryptographically Secure Random if: You want it is essential in applications like web security (e and can live with specific tradeoffs depend on your use case.
Use Non-Cryptographic Random if: You prioritize it is unsuitable for security contexts like generating encryption keys, tokens, or passwords, where cryptographic random methods are required to prevent predictability and ensure safety over what Cryptographically Secure Random offers.
Developers should use cryptographically secure random when generating data for security-sensitive operations, such as creating encryption keys, session tokens, passwords, nonces, or initialization vectors in cryptographic systems
