Generate an alphanumeric string (token generator)

openssl rand -base64 48 | tr -dc 'a-zA-Z0-9' | head -c 32
•	openssl rand -base64 48 generates a random string.
•	tr -dc 'a-zA-Z0-9' filters out any characters that are not alphanumeric.
•	head -c 32 truncates the string to the desired length (32 characters in this example). Adjust the length as needed.
