I added the line
require 'files task'
to the code from your listing.
The result fails under J6 and J7 (I have not tried J8 beta):
J6 fails like this:
'd n'=: 'mruJfgd0RG' newandgetrsa 'pascaljasmin.txt'
|value error: dfh
| pD pubrsa=.a.{~_2
dfh\,>}:^:(':'={:)each(#~0,@:-.@:=$&>),;:>('-----BEGIN PUBLIC
KEY-----'Boxlink'-----END PUBLIC KEY-----')(}.@:}:@:takerange{])l
J7 fails like this:
'd n'=: 'mruJfgd0RG' newandgetrsa 'pascaljasmin.txt'
|index error: nkec
| privh=.,>}:^:(':'={:)each(#~0,@:-.@:=$&>),;:>2 3 4 {l
I am also wondering about those blank lines I am seeing.
(And, yes, that is a random and arbitrary example password - one which
I have no intention of using.)
Thoughts?
Thanks,
