I'd like to be able to do something like this

sha1sum --base64

and instead of getting a hex representation get a base64 representation.

An alternative might be

sha1sum --raw | base64

obviously this applies to md5sum, sha512sum, etc

This is one of those border line cases. I'm 40:60 against adding it as it seems easy enough to acheive using existing tools:

env printf $(sha1sum file | sed 's/ .*//; s/(..)/\x\1/g') | base64

Note using env above is to bypass the inbuilt printf which doesn't support \x on dash for example.

cheers, Pádraig.
