For random strings, I tend to use openssl (e.g. with base64 encoding);
openssl rand -base64 18
You do run the risk here of getting non-alphabetic characters here, so you
might want to filter those:
openssl rand -base64 18| sed 's|[^[:alpha:]]||g'
Or if you are fine with just hex numbers;
openssl rand 18 | hexdump -e '8 "%X" "\n"'
