In addition to the forefront of technologies such as driverless, vehicle-to-traffic mobility and connectivity, almost all of the car's windows and inner bodies are equipped with display features that showcase the future of the car as a "third livi

Fortunately, there have been many articles about the power of the Internet of things. Intelligent objects will interact with humans and their surroundings using technologies such as AI and machine learning. The most typical examples are driverless cars, drones, smart kitchens and smart homes that are also emerging. Gartner predicts that these smart objects will become increasingly interconnected and continue to improve our standar

JKS's provider is Sun, which is available in every version of the JDK, and Jceks provider is the sunjce,1.4 we can use directly.
Jceks is stronger at the security level than JKS, and the provider used is Jceks (recommended), especially on the private key in the protection KeyStore (using TripleDES).
PKCS#12 is the public key encryption standard, which stipulates that all p

What is the truth? DEP does not operate the GOPATH/SRC directory because it is shared. Dep leaves a "private plots" under $gopath/pkg/dep/sources for all cache de
