Done and attached. Hope it's fine.

Subject: [PATCH] zshrc: add openssl hash functions

Well, here's what I got in my repo now.

I'll happily push it, if people *test* and ACK this. - I didn't test
this!

Also, I would like new stuff to go in only with accompanying
documentation in doc/grmlzshrc.t2t of grml-etc-core's zshrc5 branch.

Someone who knows what the functions from this patch actually do
should write entries for them.

The guy who already writes the manual entries for the *existing* code
shouldn't be burdened with documenting *new* code, too.

So: Pretty please. :-)

Regards, Frank

Yes, I can[tm].

I'd do it like this:

[snip]
ssl_hashes=( sha512 sha256 sha1 md5 )

for sh in ${ssl_hashes}; do
    ssl-cert-${sh}() {
        emulate -L zsh
        if [[ -z $1 ]] ; then
            printf 'usage: %s <hash-name>\n' "ssh-cert-${sh}"
            printf '  where "hash-name" is one of: %s\n' "${ssl_hashes}"
            return 1
        fi
        openssl x509 -noout -fingerprint -${sh} -in $1
    }
done

ssl-cert-fingerprints() {
    emulate -L zsh
    if [[ -z $1 ]] ; then
        printf 'usage: ssl-cert-fingerprints <file>\n'
        return 1
    fi
    for i in ${ssl_hashes}
        do ssl-cert-$i $1;
    done
}

ssl-cert-info() {
    emulate -L zsh
    if [[ -z $1 ]] ; then
        printf 'usage: ssl-cert-info <file>\n'
        return 1
    fi
    openssl x509 -noout -text -in $1 
    ssl-cert-fingerprints $1
}
[snap]

I thinks that's reasonable.

Also note, that I was assuming for ssl-cert-fingerprints() and
ssl-cert-info() to take a *file* as their sole argument. I got no idea
about the workings of openssl. I'm really just a DAU with it.

Anyway, this is my take on the subject.

Regards, Frank

I can't remember all the openssl stuff on my own, that's why I wrote the 
openssl section in grml-tips. :)

Frank, can you please review? Maybe we should add some simple usage information 
if $1 is missing?

thx && regards,
-mika-

I suggest to add the following aliases/functions to grml's zshrc:

for i in sha512 sha256 sha1 md5; do
  ssl-cert-$i() { openssl x509 -noout -fingerprint -$i -in $1 }
done

ssl-cert-fingerprints() {
  for i in sha512 sha256 sha1 md5; do ssl-cert-$i $1; done
}

ssl-cert-info() {
   openssl x509 -noout -text -in $1 
   ssl-cert-fingerprints $1
}

I never can remember all the options openssl wants for displaying this very
basic information about certificates, so I guess these functions are useful for
others, too.

P.S.: I don't know why, but creating function inside a for loop doesn't seem to
work in bash (3.2). In zsh it just works[tm]. :-)
