android 指纹存储密码,Android
在使用指纹扫描器进行用户身份验证之后,我需要加密不同的字符串和相关的解密.
private boolean tryEncrypt(Cipher cipher) {
try {
cipher.doFinal(SECRET_BYTES);
String one = "augusto";
String two = "test@gmail";
String three = "3333333331";
byte[] oneEnc = cipher.doFinal(one.getBytes());
byte[] twoEnc = cipher.doFinal(one.getBytes());
byte[] threeEnc = cipher.doFinal(one.getBytes());
Log.d("test", "oneEnc: " + Base64.encodeToString(oneEnc,0));
Log.d("test", "twoEnc: " + Base64.encodeToString(twoEnc,0));
Log.d("test", "threeEnc: " + Base64.encodeToString(threeEnc,0));
} catch (Exception e) {
e.printStackTrace();
return false;
}
return true;
}
我收到此错误：
java.lang.IllegalStateException: IV has already been used. Reusing IV in encryption mode violates security best practices.
正确的做法是什么？
谢谢
