我知道还有其他几个关于该主题的问题,但他们都没有帮助我。我也尝试了BouncyCastle
库。有人可以帮我吗? PEM文件看起来像:将PEM私钥文件转换为JAVA私钥对象
-----BEGIN RSA PRIVATE KEY-----
MIIEpAIBAAKCAQEAq2eYtnTsEc/qyqS ...
... zY3WG++SA+amcXiO721hJWNC+uTbZ1bzQ==
-----END RSA PRIVATE KEY-----
我用这个方法
public static PrivateKey getPemPrivateKey(String filename) throws IOException, NoSuchAlgorithmException, InvalidKeySpecException {
File f = new File(PEMFILES_FOLDER+filename);
FileInputStream fis = new FileInputStream(f);
DataInputStream dis = new DataInputStream(fis);
byte[] keyBytes = new byte[(int) f.length()];
dis.readFully(keyBytes);
dis.close();
String temp = new String(keyBytes);
//TODO care about the linefeeds
String privKeyPEM = temp.replace("-----BEGIN RSA PRIVATE KEY-----\n", "");
privKeyPEM = privKeyPEM.replace("-----END RSA PRIVATE KEY-----", "");
System.out.println("Private key: \n"+privKeyPEM);
Base64 b64 = new Base64();
byte [] decoded = b64.decode(privKeyPEM);
PKCS8EncodedKeySpec spec = new PKCS8EncodedKeySpec(decoded);
KeyFactory kf = KeyFactory.getInstance(RSA);
return kf.generatePrivate(spec);
}
我收到此错误:
java.security.spec.InvalidKeySpecException: java.security.InvalidKeyException: IOException : algid parse error, not a sequence
