Changing encryption password?

[kernel_klink]

When I installed Fedora selected the option to encrypt the hard drive. I want to change the passphrase, is there a way to change the passphrase, or do I have to re-install Fedora?

Does default Fedora encryption use a gpg-encoded encryption key?

DM_crypt allows you to have multiple passwords so multiple users can access the media without sharing a password. Use "cryptsetup luksAddKey" to add your new password, then "cryptsetup luksRemoveKey" to remove the old password.

I tried to use the "change passphrase" option in the "Palimsest Disk Utility" Under Applications > System Tools, it did not work. I gives an error of incorrect passphrase.


How does "cryptsetup luksAddKey" and "cryptsetup luksRemoveKey" work is it used in the terminal. I went into the terminal and typed

help cryptsetup luksRemoveKey

I get message of "no help topics match.
