The current version of OPENSSL-1.0.2J does not support Google's CHACHA20 encryption algorithm. The CHACHA20 encryption algorithm is relatively safe relative to RC4, and is optimized for ARM's mobile phone, making it faster and more power-saving.However, the latest Intel processors and ARM V8 processors are optimized for AES-GCM encryption algorithms through the AES-NI instruction set, which is much faster than chacha20, so the Aes-ni encryption algorithm is preferred on devices that support AES-

To solve the two problems of OCSP, We have OCSP stapling. The website server performs OCSP queries, caches the query results, and returns the results to the browser during TLS connection with the browser, so that the browser does not need to query the results again. This solves the problemPrivacyAndPerformanceProblem.OCSP stapling Detection
