Very good of you to post the answer!
Incidentally, most of those shortcut commands for openssl can be re-created by either making a one-liner shell script, or through Fink (I'm pretty sure Fink includes a few shortcuts like md5sum).
For a one-liner shortcut, you could create a script called sha1sum with
Code:
#!/bin/bash
/usr/bin/openssl sha1 $1
You can replace "sha1" with any of the digests openssl supports.
Though, IMHO, this type of shortcut is really not that useful.
