Convert OpenSSH known_hosts for hashcat processing
/*
kh-to-hashcat allows to convert an OpenSSH known_hosts hashed file to a
format that can be used with hashcat to recover hosts.
Note that as the know_hosts file usually contains multiple keys for each host
it is wise to filter the file to a single key type to filter redundant hashes.
Check this stat:
perl -nE '$c{$1}++ if /^\|1\|[^ ]+ ([^ ]+)/;END{say "$_: $c{$_}" for keys %c}' ~/.ssh/known_hosts

Go text/template hacks

Go text/template hacks

Hacks below use goproc to experiment with Go templates from the command-line.

Convert bool to int

$ echo false | goproc -e '{{.}} => {{index "....\001\000" (len (print .))}}{{"\n"}}'
false => 0
$ echo true | goproc -e '{{.}} =&gt; {{index "....\001\000" (len (print .))}}{{"\n"}}'
