Algid parse error, not a sequence
提问by Dmitrii Pisarenko
When trying to read a RSA private key from a file using the method
尝试使用该方法从文件中读取 RSA 私钥时
public PrivateKey getPrivateKey()
throws NoSuchAlgorithmException,
InvalidKeySpecException, IOException {
final InputStream inputStream = getClass().getClassLoader()
.getResourceAsStream("privatekey");
byte[] privKeyBytes = null;
try {
privKeyBytes = IOUtils.toByteArray(inputStream);
} catch (final IOException exception) {
LOGGER.error("", exception);
IOUtils.closeQuietly(inputStream);
}
LOGGER.debug("privKeyBytes: {}", privKeyBytes);
String BEGIN = "-----BEGIN RSA PRIVATE KEY-----";
String END = "-----END RSA PRIVATE KEY-----";
String str = new String(privKeyBytes);
if (str.contains(BEGIN) && str.contains(END)) {
str = str.substring(BEGIN.length(), str.lastIndexOf(END));
}
KeyFactory fac = KeyFactory.getInstance("RSA");
EncodedKeySpec privKeySpec =
new PKCS8EncodedKeySpec(Base64.decode(str.getBytes()));
return fac.generatePrivate(privKeySpec);
}
I get the exception
我得到了例外
java.security.spec.InvalidKeySpecException: java.security.InvalidKeyException: IOException : algid parse error, not a sequence
at sun.security.rsa.RSAKeyFactory.engineGeneratePrivate(RSAKeyFactory.java:200) ~[na:1.6.0_23]
at java.security.KeyFactory.generatePrivate(KeyFactory.java:342) ~[na:1.6.0_23]
at the fac.generatePrivate(privKeySpec) call.
在 fac.generatePrivate(privKeySpec) 调用中。
What does this error mean?
这个错误是什么意思？
Thanks
谢谢

It means your key is not in PKCS#8 format. The easiest thing to do is to use the openssl pkcs8 -topk8 <...other options...>command to convert the key once. Alternatively you can use the PEMReaderclass of the Bouncycastle lightweight API.
这意味着您的密钥不是 PKCS#8 格式。最简单的方法是使用该openssl pkcs8 -topk8 <...other options...>命令将密钥转换一次。或者，您可以使用Bouncycastle 轻量级 API的PEMReader类。

I was having this same issue, and the format of the key was NOT the actual problem.
All I had to do to get rid of that exception was to call
我遇到了同样的问题，密钥的格式不是实际问题。
为了摆脱那个异常，我所要做的就是调用
java.security.Security.addProvider(
new org.bouncycastle.jce.provider.BouncyCastleProvider()
);
and everything worked
一切正常

You must make your PCKS8 file from your private key!
你必须用你的私钥制作你的 PCKS8 文件！
private.pem => name of private key file
private.pem => 私钥文件名
openssl genrsa -out private.pem 1024
public_key.pem => name of public key file
public_key.pem => 公钥文件名
openssl rsa -in private.pem -pubout -outform PEM -out public_key.pem
??private_key.pem?? => name of private key with PCKS8 format! you can just read this format in java
??private_key.pem?? => PCKS8 格式的私钥名称！你可以在java中读取这种格式
openssl pkcs8 -topk8 -inform PEM -in private.pem -out private_key.pem -nocrypt
