Username field encrypted in confluence 5.4.1

[Mustafa Abusalah]

We have upgraded confluence 5.2 to 5.4.1 when I checked the database tables I noticed that the username is encrypted in attachments and content tables, do you have any idea why the username field is encrypted? Do you know how to decrypt the field? Thank you

They're not encrypted, they're just hashes [citation needed] mapped to users in a different table.

You can decipher the username by joining the user_mapping table with whatever table you need the username from. Here's an example query for the content_label table:

SELECT * FROM confluence.content_label JOIN confluence.user_mapping ON owner=user_key;

I suspect it's done this way to preserve usernames when a user is removed from Confluence.
