尝试存储SecretKey Java时出现“线程“主”中的异常” java.security.KeyStoreException：无法存储非PrivateKeys错误

Question

我有一个将javax.crypto.SecretKey存储在密钥库中的方法。每当我调用此方法时。它吐出Exception in thread "main" java.security.KeyStoreException: Cannot store non-PrivateKeys

这是完整的追溯：

Exception in thread "main" java.security.KeyStoreException: Cannot store non-PrivateKeys
    at sun.security.provider.JavaKeyStore.engineSetKeyEntry(JavaKeyStore.java:261)
    at sun.security.provider.JavaKeyStore$JKS.engineSetKeyEntry(JavaKeyStore.java:56)
    at java.security.KeyStoreSpi.engineSetEntry(KeyStoreSpi.java:550)
    at sun.security.provider.KeyStoreDelegator.engineSetEntry(KeyStoreDelegator.java:179)
    at sun.security.provider.JavaKeyStore$DualFormatJKS.engineSetEntry(JavaKeyStore.java:70)
    at java.security.KeyStore.setEntry(KeyStore.java:1557)
    at cryptography.Cryptography.storeKey(Cryptography.java:117)
    at cryptography.Cryptography.main(Cryptography.java:27)

和相关代码：

    public static void storeKey(SecretKey key, char[] password){
            KeyStore ks = KeyStore.getInstance(KeyStore.getDefaultType());
            String keyStoreName = "C:\\Path\\To\\Keystore";
            File f = new File(keyStoreName);
            if (f.isFile()){
                ks.load(new FileInputStream(keyStoreName), password);
            }
            else{
                ks.load(null, null);
                ks.store(new FileOutputStream(keyStoreName), password);
            }
            KeyStore.SecretKeyEntry skEntry = new KeyStore.SecretKeyEntry(key);
            ks.setEntry(entryAlias, skEntry, new   KeyStore.PasswordProtection(password));

我遗漏了该方法引发的一些异常以保持其相关性。

我尝试了几种不同的保存密钥的方法，但这似乎是唯一可行的方法。

任何输入或帮助将不胜感激。
