Juniper Type-9 passwords are stored on Juniper JunOS-based devices such as the SRX series or the J series routers. These passwords are encrypted using a reversible encryption which can be reversed using this tool. The Type-9 passwords are stored in the configuration with a "$9$" at the start, for example:
snmp-community 1 {
community-name "$9$X3gxVYJGiq.5Ygi.5T/9"; ## SECRET-DATA
security-name chicken;
}
To decode the password, just copy it from the configuration and paste it in to the Juniper Type-9 password decoder and the unencrypted password will be shown automatically.
You can see that the decoded Juniper SNMP community string from the configuration was "public".
