Export local user data to a file.
There are two kinds of user files:
zx export user.
zx export user dangerous.
Public files have user metadata and the public half of a user's keys. Dangerous files have user metadata and both public and private keys (hence the danger involved!)
Public user files are used by sysops to create a user account on a realm's prime node so that the user can be made a packager or manager for projects carried by that realm.
Dangerous user files are used by developers to transfer user data (including signing keys) between systems used to submit/approve/accept packages to a realm.
Exporting public user data to a .zpuf file to send to a sysop:
taro@okonomiyaki:~$ zx export user Realm otpr selected. Wrote Zomp public user file to otpr-taro.zpuf. This file can be given to a sysop from otpr and added to the realm. It ONLY contains PUBLIC KEY data.
Exporting private user data to a .zpuf file for transfer to a system owned by the same user:
taro@okonomiyaki:~$ zx export user dangerous Realm otpr selected. Wrote Zomp DANGEROUS user file to otpr-taro.zduf. WARNING: This file contains your PRIVATE KEYS and should NEVER be shared. Its only use is for the `import user [.zduf]` command! Importing the user will only work if you have first imported realm otpr.
