Replace random string generation method with OpenSSL for better randomness in install.sh

Browse source 
The previous implementation using cat /dev/urandom | tr caused tr to hang and consume 100% CPU on certain environments (e.g., GCP, specific kernels) due to delayed SIGPIPE handling. Using openssl provides a finite, cryptographically secure string that eliminates this CPU spike and is noticeably faster."
