Some times I need random string, for example to use as email seperator or to use in some API. One way is to use tools like /dev/[u]random or od and other such. But they seem cubersome after I figured this out.
openssl rand <length> openssl rand 10
This alone without some parameters is not interesting thoug. You can use ‘-base64’ or ‘-hex’ to select the encoding.
So if you execute the above you will get something like this
$ openssl rand -hex 10 591e96110af8aecb760b $ openssl rand -base64 10 TnuUXuiZXv2ktw==
