大家好我在尝试复制并粘贴已生成的ssh2公钥时出现此错误。

这是转换为字节数组并使用x509 keyspec
的代码byte[] key = Base64.encodeBase64(publicKey.getBytes());
x509KeySpec = new X509EncodedKeySpec(key);
keyFactory = KeyFactory.getInstance("RSA");
return keyFactory.generatePublic(x509KeySpec);
答案 0 :(得分：0)
encodeBase64编码到base 64.我想你想解码公钥，而不是编码它。当然，如果您手动解码，您应首先剥离页眉和页脚。最后，SSH使用它自己的密钥格式，因此您应该使用读取SSH公钥的库，而不仅仅是用于X509KeySpec的解码器。
