输入字节数组有错误的4字节结束单元

Question

我正在尝试使用X509和KeyFactory将以下字符串转换为公钥。到目前为止我写的代码是:

public static void main(String args[]) throws Exception {
String key = "MIICIjANBgkqhkiG9w0BAQEFAAOCAg8AMIICCgKCAgEAidRWp1iB0s2LKnAyAxUKCMmsKK9bMTdRUItZVRcV4lB0RXGla0wRTNeR6r5oqNo6poHUJ+QGPjAHDCztMjAZdtuMSQ+Lohn+TjDMIEi2sUNeXhZuXchwEE+3QTgPpIOGhjJtv4wmTjXD5UaZbYWuydNpgvFEDsF4jf02xM8t8a7nOgQIriPi83fa4XHXcoCcG"
+ "EHDbpbtYUhVq12rJEBXUoVM1zi9LcDhEsgilpzRPlkT6zC+89SkgYHWTRtO2shLpJcnThkR1nyLqHU2Zgn1hSrNsy+T97bNL1Umhcs7e94WJ7WWO6PoSst4cknPIZhhRbeBHoJ9rdV+XLBoew7buDQSht2Jn"

+ "7lkageikM4D6mq6vQ5fkedfzz8PuvQNe8BH3h2UZYmRjNvfKd8wt2bRKKFK7K4jCYT5riYo+5aEWS"
+ "SrWvL+ECAwEAAQ==";
getKey(key);
}
public static PublicKey getKey(String key){
try{
byte[] byteKey = Base64.getDecoder().decode(key.getBytes());    
X509EncodedKeySpec X509publicKey = new X509EncodedKeySpec(byteKey);
KeyFactory kf = KeyFactory.getInstance("RSA");
return kf.generatePublic(X509publicKey);
}
catch(Exception e){
e.printStackTrace();
}
return null;
}

我收到的错误如下:

java.lang.IllegalArgumentException: Input byte array has wrong 4-byte ending unit
at java.base/java.util.Base64$Decoder.decode0(Base64.java:781)
at java.base/java.util.Base64$Decoder.decode(Base64.java:567)
at WannaCry.getKey(WannaCry.java:46)
at WannaCry.main(WannaCry.java:27)

我不确定我是否得到了错误的关键，因为这是我的任务。这是我必须使用的密钥

我当然删除了所有的换行符("/")但是我得到了这个错误，或者有时我得到

无效字节数组字符D
