我正在使用以下代码解密消息
try {
byte[] iv = { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 };
IvParameterSpec ips = new IvParameterSpec(iv);
// we generate a AES SecretKeySpec object which contains the secret key.
// SecretKeySpec secretKey = new SecretKeySpec(secret, "AES");
Cipher cipher = Cipher.getInstance(ENCRYPTION_METHOD);
cipher.init(Cipher.ENCRYPT_MODE, getSecretKeySpec(), ips);
byte[] cipherText = cipher.doFinal(textToEncrypt.getBytes());
byte[] base64encodedSecretData = Base64.encodeBase64(cipherText);
String secretString = new String(base64encodedSecretData);
return secretString;
} catch (Exception e) {
e.printStackTrace();
Log.e(TAG, "Encryption error for " + textToEncrypt, e);
}
return "";
这是我的 getSecretKeySpec()
public static Key getSecretKeySpec() {
if (SECRET_KEY == null) {
byte[] keyBytes = new byte[16];
// byte[] bytes = Globals.APPLICATION.APP_KEY.getBytes();
byte[] bytes = Globals.context.getPackageName().getBytes();
if (bytes.length > 16) {
int j = 0;
for (int i = bytes.length - 1; i >= 0; i--) {
keyBytes[j] = bytes[i];
j++;
if (j > 7)
break;
}
} else {
for (int i = 0; i < 16; i++)
keyBytes[i] = 'q';
int j = 0;
for (int i = bytes.length - 1; i >= 0; i--) {
keyBytes[j] = bytes[i];
}
}
SECRET_KEY = new SecretKeySpec(keyBytes, "AES");
}
return SECRET_KEY;
}
我在 SO 和其他人中搜索了很多,但无法解决这个问题。谁能指出我的错误。
