起因

做一个SDK的对接，需要用到签名的SHA256
不是太明白细节原理，还是先按照文档来获取

sha256获取
拿不到的SHA256

先拿一个我常用的jks试试水看看
输入 keytool -v -list -keystore xxx.jks
前面输入部分正常

但是签名部分

MD5和SHA1内容都是正常的
SHA256: SHA256withRSA 怎么看上去都不像是一个“正常”的内容

Plan B

文档上看都是用keytool命令行一条路了。
Plan B只能另找出路，还好StackOverflow没有让我失望过

keytool : SHA256withRSA written instead of an actual SHA256 on my production keystore

上面说这是一个keytool的一个bug，是locale设置引起，当然这个bug起因也不深究了。
可以用gradle signingReport来解决
还有小插曲JAVA版本不匹配

这个问题在做命令行单元测试的时候碰到过，切一下后解决

解决方法
