WeChat now has a small program called "MiXin" for information encryption

Tencent has now launched an information encryption mini-program "Tencent Secret Message" on WeChat. According to the official introduction of the mini-program, with the development of the Internet, more and more sensitive data need to be transmitted on open networks. The mini-program adopts national secret algorithms to protect the transmission of sensitive data through data encryption and digital signatures.

It is reported that Tencent Secret Message users need to be responsible for the integrity and correctness of the master key. All losses and consequences caused by the incorrect use or loss of the master key due to improper maintenance by the user, which leads to the inability to decrypt the encrypted data, shall be borne by the user. After completing the registration, you can start to create Secret Message. After filling in the Secret Message content, you can add a note to describe the purpose of the Secret Message, such as passing a file password. After completion, you can manually add recipients, and only the specified recipients can view it.

The mini program also provides an option for the expiration date of the secret message. After the expiration date, the secret message cannot be viewed. After the secret message is successfully created, a secret message QR code will be generated. The creator can download the QR code and send it to the recipient by sharing it on WeChat. The recipient can open and decrypt it directly in the chat box, or use WeChat to scan the corresponding QR code to view the secret message.

However, the Tencent MiXin mini program is currently undergoing system update and maintenance, and searches do not yet display results. It is unclear when it will be online again.
