it's ASCII and in the Mail potentially base64... :)
surely it is a list of hex values for the bytes (a "hex dump")
in which language? Simplest is perl, use something like:
perl -e 'my $ahex = $ARGV[0] || jn("", <>);chomp $ahex;$ahex =~
tr|0-9A-Fa-f||cd;print pack("H*", $ahex);'
and feed via STDIN and get binary via STDOUT.
Often also it can be helpful to use such a small perl script to
generate source code when someone wants to embed test keys in
source code, for example certificates to be included in unit
tests or have a small parser in the target language that takes
the output of the tool as input to ease maintenance.
I think there is a standard tool to convert binary data to C
code, but I cannot find it. Maybe `od' is a starting point for an
own construction.
