我正在尝试用Java解密密码加密的私钥,并且遇到过这个previous question,但是当我尝试相同的操作时,会遇到以下异常:
Exception in thread "main" java.io.IOException: ObjectIdentifier() -- data isn't an object ID (tag = 48)
at sun.security.util.ObjectIdentifier.<init>(ObjectIdentifier.java:257)

at TestDecryptKey.main(TestDecryptKey.java:65)
其中TestDecryptKey.java是我的测试文件。这是我在做什么的摘要:
import javax.crypto.EncryptedPrivateKeyInfo;
import javax.crypto.spec.PBEKeySpec;
import java.util.Base64;
import java.security.GeneralSecurityException;
import java.io.IOException;
public class TestDecryptKey {
public static void main(String[] args) throws GeneralSecurityException, IOException {
String encryptedBase64PrivateKey = "MII...";
String password = "...";
byte[] encryptedPrivateKey = Base64.getDecoder().decode(encryptedBase64PrivateKey.getBytes("UTF-8"));
PBEKeySpec pbeSpec = new PBEKeySpec(password.toCharArray());
// Exception is thrown here
EncryptedPrivateKeyInfo encryptedPrivateKeyInfo = new EncryptedPrivateKeyInfo(encryptedPrivateKey);
}
}
我假设它声称我提供的加密密钥数据不是有效的加密密钥,但是openssl不同意。我将Base64字符串的页眉和页脚“ ----- BEGIN加密的私钥-----”和“ ----- END加密的私钥-----”保存为文件“ pem_key”和使用以下命令和上面的密码:
openssl pkcs8 -inform pem -in pem_key -outform der
我能够输出解密的密钥字节。我要去哪里错了?
