I'm having issues attempting to decrypt my root partition from the initramfs environment. All I can seem to observe is that after entering my password cryptsetup locks up not ever returning control of the terminal. Trying this both in the initial boot and in the rescue prompt yields the same results but when booting with an Arch Live image cryptsetup is able to decrypt within a few seconds.

Asking here because I have a suspicion this might be related to the mkinitcpio package distributed by Obarun. If I can provide any information let me know, I'm not entirely sure what would be helpful.
What's listed in the BINARIES section in the respective mkinitcpio.conf files of your Obarun & Arch Live systems?

If nothing is listed in the Obarun mkinitcpio.conf, try adding 
/usr/bin/cryptsetup
and maybe also 
/usr/bin/dmsetup /usr/bin/lvm
if you're using lvm2 in conjunction with your cryptsetup.
Thanks nfg, doing that worked like a charm!

Do you have any idea how this issue could have happened? I'd like to be able to fix this weird issue so that I wouldn't need to include extra files when i'm already doing things that follow the Arch wiki.
