X509Util

❓Introduction

This is a java util class mainly with some methods to generate X509V3Certificate and X509v2CRL.

There are three ways to generate certificates in the utility class, using the following three different JCE API:

1. X509V3CertificateGenerator（Deprecated, but still valid）
2. X509v3CertificateBuilder（Not recommended, because its DN uses X500Name）
3. JcaX509v3CertificateBuilder（extended X509v3CertificateBuilder, is the best choice）

There are a number of other helper methods in the utility class, with detailed explanations in the comments.
