java(groovy)读取密钥RSA签名报错?报错
关于海外支付宝app使用RSA签名有错误 特此请教：
签名代码：（根据给出的demo中的代码）
/**
* 对参数做签名
*
* @param content 拼接后的串
* @param keyName privateKey
* @return 签名后的字符串
*/
public String sign(String content, String keyName) {
try {
//get privateKdy from object storage
// String privateKey = readKeyCertData(keyName);
String privateKey = "你懂的.."
PKCS8EncodedKeySpec priPKCS8 = new PKCS8EncodedKeySpec(Base64.decode(privateKey));
KeyFactory keyFactory = KeyFactory.getInstance(ALGORITHM)
logger.info("----------" + priPKCS8)
//todo 这里报错编译过不去
PrivateKey priKey = keyFactory.generatePrivate(priPKCS8)
java.security.Signature signature = java.security.Signature
.getInstance(SIGN_ALGORITHMS);
signature.initSign(priKey);
signature.update(content.getBytes(DEFAULT_CHARSET));
return Base64.encode(signature.sign());
} catch (Exception e) {
logger.error("RSA签名错误...")
e.printStackTrace();
return "";
}
}

备注：
1 本代码只涉及签名服务 不是在app开发中
2
密钥直接使用string 或者 txt文件 均报错
目测是提示密钥格式不对，但是所使用的公钥密钥都已经确认过，是真实线上使用的 望指教！

https://developer.aliyun.com/profile/5yerqm5bn5yqg?spm=a2c6h.12873639.0.0.6eae304abcjaIB应该还是privatekey有问题
StringprivateKey=readKeyCertData(keyName);
你还是确定下privatekey和你线程的字符串是不是一样。
可能其实是不需要做base64解析的。
确实是privateKey的问题。结贴。。引用来自“iehyou”的评论

AlipayClientalipayClient=newDefaultAlipayClient("https://openapi.alipay.com/gateway.do",APP_ID,APP_PRIVATE_KEY,"json",CHARSET,ALIPAY_PUBLIC_KEY,"RSA2");其中参数 APP_PRIVATE_KEY是你用支付宝密钥生成器生成的以pkcs8结尾的文件(去掉注释),而ALIPAY_PUBLIC_KEY是支付宝密钥是支付宝生成的(根据你的公钥?私钥?)在平台配置页面可以获取到
