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.
