加密是類似下面的方法，鹽值是在/data/data/com.android.providers.settings/databases/settings.db資料庫secure的表裡面，你檔案裡面看到的就是sha1+md5: (40位+32位)的值

public byte[] passwordToHash(String password)

{

if (password == null)

{

return null;

}

String algo = null;

byte[] hashed = null;

try

{

byte[] saltedPassword = (password + getSalt()).getBytes();

byte[] sha1 = MessageDigest.getInstance(algo = "SHA-1").digest(saltedPassword);

byte[] md5 = MessageDigest.getInstance(algo = "MD5").digest(saltedPassword);

hashed = (toHex(sha1) + toHex(md5)).getBytes();

}

catch (NoSuchAlgorithmException e)

{

Log.w(TAG, "Failed to encode string because of missing algorithm: " + algo);

}

return hashed;

}

簡單來說就是sha1+MD5加鹽，這種加密方法目前無法破解
