Cryptographically Secure Random vs Deterministic 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 learn and use deterministic random when building applications that require reproducible results, such as in unit testing, game development (e. Here's our take.

Cryptographically Secure Random

Nice Pick

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

Pros

• It is essential in applications like web security (e
• Related to: encryption, cryptography

Cons

• Specific tradeoffs depend on your use case

Deterministic Random

Developers should learn and use deterministic random when building applications that require reproducible results, such as in unit testing, game development (e

Pros

• g
• Related to: random-number-generation, seed-management

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 Deterministic Random if: You prioritize g over what Cryptographically Secure Random offers.

The Bottom Line

Cryptographically Secure Random wins

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
