公开金钥)应该看起来像这样:
< RSAKeyValue>
< Modulus> yNi8BvATA77f + / 6cU6z [...] 9VULgU =< / Modulus>
< Exponent> AQAB< / Exponent>
< / RSAKeyValue>
The Public Key (arg) should look like this: <RSAKeyValue> <Modulus>yNi8BvATA77f+/6cU6z[...]9VULgU=</Modulus> <Exponent>AQAB</Exponent> </RSAKeyValue>
私钥(arg)应如下所示:
