The string is too long to fit on one line. The "openssl base64" decoder
requires long strings to be split over multiple lines. As you can see, the
limit is 80 characters per-line:
$ let i=15; while (( i < 25))
do
echo $i $(perl -e "printf qq{%s\n}, q{AAAA} x $i" |
openssl base64 -d | wc -c)
let i=i+1
done
15 45
16 48
17 51
18 54
19 57
20 0
21 0
22 0
23 0
24 0
Also each line MUST end with "\n" or "\r\n", incomplete last lines don't
work:
$ let i=15; while (( i < 25))
do
echo $i $(perl -e "printf qq{%s}, q{AAAA} x $i" |
openssl base64 -d | wc -c)
let i=i+1
done
