英文:
Md5 to String in android studio
问题
以下是翻译好的部分：
我正在使用Md5来处理共享首选项，但是当我获取共享的数据时，看到的是加密的结果。
public static String md5(final String s) {
final String MD5 = "MD5";
try {
// 创建 MD5 哈希
MessageDigest digest = java.security.MessageDigest.getInstance(MD5);
digest.update(s.getBytes());
byte messageDigest[] = digest.digest();
// 创建十六进制字符串
StringBuilder hexString = new StringBuilder();
for (byte aMessageDigest : messageDigest) {
String h = Integer.toHexString(0xFF & aMessageDigest);
while (h.length() < 2)
h = "0" + h;
hexString.append(h);
}
return hexString.toString();
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
}
return "";
}
以下代码用于从共享首选项获取数据，但我看不到数据，只能看到经过MD5加密的结果。
sharedPreferences = getSharedPreferences(nameshe, MODE_PRIVATE);
String nam = sharedPreferences.getString(sa, "jan");
String names = md5(nam);
textView.setText(names);
英文:
I am using Md5 for sharedpref
now when I get the data shared but see encrypted it
public static String md5(final String s) {
final String MD5 = "MD5";
try {
// Create MD5 Hash
MessageDigest digest = java.security.MessageDigest
.getInstance(MD5);
digest.update(s.getBytes());
byte messageDigest[] = digest.digest();
// Create Hex String
StringBuilder hexString = new StringBuilder();
for (byte aMessageDigest : messageDigest) {
String h = Integer.toHexString(0xFF & aMessageDigest);
while (h.length() < 2)
h = "0" + h;
hexString.append(h);
}
return hexString.toString();
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
}
return "";
}
this codes for get the data from shared, I can not see data, i only see the encripted md5
sharedPreferences=getSharedPreferences(nameshe,MODE_PRIVATE);
String nam=sharedPreferences.getString(sa,"jan");
String names =md5(nam);
textView.setText(names);
