IM Encrypt

1. Why do I need to encrypt?

I often need to transmit sensitive information, personal information on the network. But often SMS, eMail is not encrypted transmission, that is, this information will be exposed to the transmission.

In addition, my common Messenger, Facebook, WhatsApp, Wechat, Line, Telegram dialogue information is operator control, that is, personal conversation information is a risk of leakage.

I often need to store sensitive information and personal information on my mobile phone. But these files are stored in plain text, that is, they will be exposed to risk.

2. What is Clipboard Encrypt

A tool to encrypt and decrypt sensitive information, all apps can use it when editing text.

3. How to use Clipboard Encrypt

The usage is very simple, set the password for encryption and decryption, after opening the function:

* If it is plain text: long press text -> select text -> copy -> paste to achieve encryption

* If it is ciphertext: long press text -> select text -> copy -> paste to achieve decryption

* The ciphertext looks like {{ciphertext}}

4. When to use Clipboard Encrypt

* The SMS sender and receiver agree on the password, the sender encrypts when composing, and the receiver decrypts after receiving the message.

* The eMail sender and receiver agree on the password, the sender encrypts when composing, and the receiver decrypts after receiving the message.

* The sender and receiver of the Messenger agree on the password, the sender encrypts when composing, and the receiver decrypts the message after receiving it.

* Encrypt when composing text, decrypt when restoring text

5. Is Clipboard Encrypt safe?

Clipboard Encrypt uses the standard AES encryption algorithm.

It uses AES with a random salt and random IV. The salt and IV (which are not considered sensitive information) are saved at the beginning of the data.

6. What is AES

AES is based on a design principle known as a substitution–permutation network, and is efficient in both software and hardware. Unlike its predecessor DES, AES does not use a Feistel network. AES is a variant of Rijndael which has a fixed block size of 128 bits, and a key size of 128, 192, or 256 bits.
