Simple Text Crypt
使用 AES256 加密純文本
新版本 5.1
The encryption algorithm upgraded from old AES CBC to the new AES GCM.
Key deriving algorithm also upgraded from PBKDF2 to Argon2.
A "Legacy Decrypt" button added so user can decrypt messages that were encrypted
with the older versions.

This app does not claim any permissions, so you can trust that it cannot send
any of your private data to anyone.
Messages produced by this app are secure and, for example, can be
confidently sent over a network. It uses AES in GCM mode with no padding for
encryption. It uses Argon2 and a random Salt to derive a secure key from the
entered passphrase.
This is a very powerful encryption. It also encrypts its settings before storing
them on the device.
However, the app might be vulnerable to some attacks. Although it is secure
enough to stand attacks from non-expert crackers, e.g. normal users,
should not be used for serious data encryption.
Upgrading from 4.x to 5.x
The encryption of the settings is changed. The app should be able to detect the
old settings and upgrade them with the new encryption algorithm. However, it's
a good idea to back-up your passphrase. (Well, it's generally a good idea to
back-up encryption keys and passwords in a secure place).
If the app didn't work after upgrade, uninstall and install it again.
