[dev] Reg. Frr-www gpg passphrase

Hi, I am not sure if it's the right forum to ask queries on frr web server. If not, pls ignore. Apologies! While following steps in readme for source installation of frr web the following command asks for "pass phrase". Can some one provide pointers to what the pass phrase for the file is? Command: *Sudo gpg frrouting.ssl.tar.gpg*
