Working for me on all my encrypted drives.
Did have some wonkiness at first. Disk Utility to mount, get the prompt for password/key, click the "save to Keychain" box. Second time mounting, got the Keychain prompt for "xxxx needs to access your Keychain": if do a enter/return after typing account password, will do a simple "Allow". The next time this happened, made sure to click "Always Allow" and has been working perfectly since.
So, might want to pull up Keychain Access, find the entry in login keychain, then click on the "Access Control" tab to see what checkboxes are on/off and if Disk Utility is in the list of who can use the entry (can add Disk Utility via same dialog).
