这个问题已经困扰我好几年了！ 要解决此问题需要更改哪些键？
背景：大小为2048的ssh rsa密钥可以以前导1或0开头。前导0导致该密钥被某些软件视为长度2047。这些密钥似乎不符合标准，因此最新软件库不接受它们。
用于允许2047大小rsa密钥的较旧的Java版本和默认加密库。较新的Java没有。 “”“ java.security.InvalidAlgorithmParameterException：DH密钥大小必须是64的倍数，并且只能在512到8192（含）范围内。看不到特定的密钥大小2047。”“”
我们看到的是，当詹金斯升级时，现在可以使用CVS访问的作业不起作用：-（
如果不重建jenkins以使用不同的安全性库，是否可以解决此问题？
尝试生成RSA大小为4096的CVS用户密钥。没有成功。错误所在是CVS服务器主机密钥还是CVS用户密钥？

ssh-keygen -t rsa -b 4096
可以使用不同的密码库解决错误： DH key size must be multiple of 64, and can only range from 512 to 2048 (inclusive)
2047和2048个RSA密钥长度： https://security.stackexchange.com/questions/90169/rsa-public-key-and-private-key-lengths
