RSA证书说明

标签：int   pem   imu   nbsp   ida   ring   aik   boa   tcp   

公钥证书采用的是X509证书：

openssl asn1parse -in rsa_public_key.pem -strparse 18

03 81 8D 00//03代表是bit string数据字段

30 81 89

02 81 81 //81表示长度域为1个字节，长度为0x81,代表的是n

02 03 01 00 01//直接用长度表示，03表示有3个字节，02代表的是整值数据类型，010001数据代表的是e值

长度说明：如果长度小于127，那么用一个字节表示，如果长度大于127，大于01111111，后续字节第一位为1表示长度域有几个字节

一般情况，公钥证书采用的是509的格式，但是私钥证书采用的格式不一样，一般采用的是pcks1的格式，

私钥证书：

从数据可以看到，数据字段的内容都是以02开头，代表的就是整形数据内容，接着就是长度内容，整个数据内容是按着一定的格式进行排列的；一定的数据格式进行排列，必须按一定顺序进行排列的，并且没有公钥一样的情况，没有进行包括的嵌套格式内容；私钥证书里面包含的有公钥证书内容，证书包含的内容为：n,e,d,p,q,dp,dp,qinv共8项数据
