Decrypting encrypted public XasPos messages

Last updated: July 2, 2025

Introduction​

Following the implementation of the new BBJProjeK operative policies, encrypted public XasPos messages can now be published. These messages will appear in the monthly public ticket list alongside standard entries, though their contents will remain encrypted.

Sending an encrypted public message​

The way of sending an encrypted public messages right into the monthly ticket list is the same as a regular message, but you'll have to include "encrypt:" before the email's subject (without quotation marks).

Decrypting the message​

XasPos Messenger will encrypt the messages using Base64 encoding with a custom cryptographic key. Upon successful submission of the encrypted message, XasPos will generate a unique decryption key, or passphrase for the message, and will reply to your email with this information.

You'll need that key for decrypting the message. The key should be provided to any authorized party seeking access to its contents.

There are several tools for decrypting base64, you can use this one as an example: https://emn178.github.io/online-tools/aes/decrypt/.

Make sure the input encoding is set to Base64, the Key Type to PBKDF2 and include the given encryption key.
