有谁知道默认的Java加密行为是什么:
SecretKeySpec localSecretKeySpec = new SecretKeySpec(arrayOfByte, "AES");
Cipher localCipher = Cipher.getInstance("AES");

具体来说,我希望了解这些类如何生成IV,以及仅指定"AES"时的默认加密模式是什么.谢谢.
我想使用带有16字节密钥的128位AES加密来加密和解密密码.我javax.crypto.BadPaddingException在解密值时遇到错误.在解密时我错过了什么吗?
public static void main(String args[]) {
Test t = new Test();
String encrypt = new String(t.encrypt("mypassword"));
System.out.println("decrypted value:" + t.decrypt("ThisIsASecretKey", encrypt));
}
public String encrypt(String value) {
try {
byte[] raw = new byte[]{'T', 'h', 'i', 's', 'I', 's', 'A', 'S', 'e', 'c', 'r', 'e', 't', 'K', 'e', 'y'};
SecretKeySpec skeySpec = new SecretKeySpec(raw, "AES");
Cipher cipher = Cipher.getInstance("AES");
cipher.init(Cipher.ENCRYPT_MODE, skeySpec);
byte[] encrypted = cipher.doFinal(value.getBytes());
System.out.println("encrypted string:" + (new String(encrypted)));
return new String(skeySpec.getEncoded());
