Password Compatability

Attachment Airlock expects passwords to be UTF-8 encoded. If a file is encrypted with a password containing special characters (e.g., ç, ü, ñ) using older tools or systems that use legacy encodings like CP437 or ISO-8859-1, unlocking may fail due to encoding mismatches.

Using Attachment Airlock

With Attachment Airlock enabled, users can unlock password-protected attachments in a secure environment and have them analyzed by xorlab. When an email with a password-protected attachment is sent to an XSP user, and the password protection can’t be automatically cracked by xorlab, the user receives the following notification email: Airlock notification By clicking the Unlock safely link, you are redirected to the SSQ portal with the preview of the quarantined message (if the main SSQ page is opened instead, just click the Attachments tab and click the message): Airlock message preview To unlock the message, click Unlock and enter the password for the attachment: Enter the attachment password With the provided password, xorlab starts analyzing the attachment and informs you about it: Unlocking the attachment After a successful analysis, if the attachment is safe, the message is unlocked and delivered to your mailbox: Unlocked message
