And also:

 sha1sum FILE | xxd -r -p | base64



With no further comments in the last 7 years,
I'm closing this bug.

 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.

I just dug out an old script of mine that did
low level manipulations like this, and I had used:

openssl dgst -sha1 -binary $file | openssl enc -base64

While that does show there is a need for this,
it also shows there are widely available tools
to do it already.

cheers,
Pádraig.
