I'm sure that it will be a mess to do it via openssl utility. Some time
ago I wrote a tool for showing onion addresses for private key files.
Now I pushed a feature to it to display relay fingerprint (because 
onion address is a truncated fingerprint base32 encoded...).

$ go get https://github.com/nogoegst/whatonion

$ whatonion -fp /path/to/secret_onion_key

Hope it helps, enjoy!
