mount -t ecryptfs [lower directory] [ecryptfs mount point]
mount.ecryptfs is eCryptfs mount helper. The mount utility will defer to the mount helper to perform various configuration tasks; use the -i option to bypass the mount helper if you would rather manually specify your mount options. To mount eCryptfs, specify the lower directory (i.e., /root/crypt) for the encrypted files and the eCryptfs mountpoint (i.e., /mnt/crypt) for the decrypted view of the files:
mount -t ecryptfs /root/crypt /mnt/crypt
