I have an encrypted partition that I created in another distro, and I can't unlock it in arch linux. The problem is that the proper ciphers are not installed.
cryptsetup luksDump on the partition gives this information:
Version: 1
Cipher name: serpent
Cipher mode: xts-essiv:sha256
Hash spec: sha1
However, when I check my supported ciphers with cat /proc/crypto, I get
name : ecb(arc4)
driver : ecb(arc4-generic)
module : ecb
priority : 0
refcnt : 3
selftest : passed
type : blkcipher
blocksize : 1
min keysize : 1
max keysize : 256
ivsize : 0
geniv : <default>name : arc4
driver : arc4-generic
module : arc4
priority : 0
refcnt : 3
selftest : passed
type : cipher
blocksize : 1
min keysize : 1
max keysize : 256name : stdrng
driver : krng
module : kernel
priority : 200
refcnt : 1
selftest : passed
type : rng
seedsize : 0
In Ubuntu I've checked to make sure they are installed this way. I imagine its the same in Arch. What packages do I need to install to use serpent in XTS mode?

did you load the module?
try:
modprobe aes-i586 #or maybe more like:
modprobe aes-x86_64 #depending on your architecture
