Find the disk:

$ dmesg | grep CRYPTO
sd3 at scsibus4 targ 2 lun 0: <OPENBSD, SR CRYPTO, 006> SCSI2 0/direct fixed

# disklabel sd3
... size offset fstype [fsize bsize cpg]
a: 488279018 64 RAID
...

Unlock it:
# bioctl -c C -l /dev/sd3a softraid0
<enter passphrase>
... attached as sd4 ...

# disklabel sd4
...

Mount partitions:
# mount /dev/sd4k /mnt/home


Good luck,
