True Random Number Generation vs Cryptographically Secure Pseudo 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 meets 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. Here's our take.
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
True Random Number Generation
Nice PickDevelopers 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
Cryptographically Secure Pseudo 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
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
The Verdict
Use True Random Number Generation if: You want 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 and can live with specific tradeoffs depend on your use case.
Use Cryptographically Secure Pseudo Random Number Generation if: You prioritize it is essential in applications like blockchain, secure communications, and financial software to prevent attacks like brute-force or prediction-based exploits over what True Random Number Generation offers.
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
