我不想生成新的公钥,有人向我发送他的公钥(类型PublicKey.sql
),然后我用这个密钥加密一些文本并将其保存在Oracle DataBase
中。
我找到了一种阅读公钥的方法,但我得到了这个Exception
:
java.io.StreamCorruptedException: invalid stream header: 33303832
at java.io.ObjectInputStream.readStreamHeader(Unknown Source)
at java.io.ObjectInputStream.<init>(Unknown Source)
at ge.georgiancard.app.main.App.readKeyFromFile(App.java:36)
at ge.georgiancard.app.main.App.rsaEncrypt(App.java:67)
读取密钥的方法:
public static Key readKeyFromFile() throws IOException {
InputStream in = new FileInputStream(PUBLIC_KEY_FILE);
ObjectInputStream oin = new ObjectInputStream(new BufferedInputStream(in));
try {
BigInteger m = (BigInteger) oin.readObject();
BigInteger e = (BigInteger) oin.readObject();
KeyFactory fact = KeyFactory.getInstance("RSA");
return fact.generatePublic(new RSAPublicKeySpec(m, e));
} catch (Exception e) {
throw new RuntimeException("Spurious serialisation error", e);
} finally {
oin.close();
System.out.println("Closed reading file.");
}
}
答案 0 :(得分:0)
当使用stream读取和写入数据存在差异时,会发生这种情况。似乎除了ObjectOutputStream之外还写了密钥。
