Can you use OpenSSL to generate an md5 or sha hash on a directory of files?

I'm interested in storing an indicator of file / directory integrity between two archived copies of directories. It's around 1TB of data stored recursively on hard drives. Is there a way using OpenSSL to generate a single hash for all the files that can be used as a comparison between two copies of the data, or at a later point to verify the data has not changed?
