Cryptographically Secure Pseudo Random Number Generation vs True Random Number Generation

Developers should learn and use CSPRNG when building systems that require high security, such as generating encryption keys, session tokens, passwords, or nonces in protocols like TLS or OAuth meets developers should learn and use trng in security-critical applications such as cryptography, encryption key generation, secure authentication tokens, and gambling systems where predictability could lead to vulnerabilities or unfairness. Here's our take.

Cryptographically Secure Pseudo Random Number Generation

Nice Pick

Developers should learn and use CSPRNG when building systems that require high security, such as generating encryption keys, session tokens, passwords, or nonces in protocols like TLS or OAuth

Pros

• It is essential in applications like blockchain, secure communications, and financial software to prevent attacks like brute-force or prediction-based exploits
• Related to: cryptography, security-engineering

Cons

• Specific tradeoffs depend on your use case

True Random Number Generation

Developers should learn and use TRNG in security-critical applications such as cryptography, encryption key generation, secure authentication tokens, and gambling systems where predictability could lead to vulnerabilities or unfairness

Pros

• It is essential when high-quality randomness is required to prevent attacks like brute-force or statistical analysis, such as in blockchain technologies, secure communications, and scientific simulations that demand genuine randomness
• Related to: cryptography, entropy-sources

Cons

• Specific tradeoffs depend on your use case

The Verdict

Use Cryptographically Secure Pseudo Random Number Generation if: You want it is essential in applications like blockchain, secure communications, and financial software to prevent attacks like brute-force or prediction-based exploits and can live with specific tradeoffs depend on your use case.

Use True Random Number Generation if: You prioritize it is essential when high-quality randomness is required to prevent attacks like brute-force or statistical analysis, such as in blockchain technologies, secure communications, and scientific simulations that demand genuine randomness over what Cryptographically Secure Pseudo Random Number Generation offers.

The Bottom Line

Cryptographically Secure Pseudo Random Number Generation wins

Developers should learn and use CSPRNG when building systems that require high security, such as generating encryption keys, session tokens, passwords, or nonces in protocols like TLS or OAuth
