I have been getting the following error whenever i try to create a build to Salesforce. May i know what changes i need to make on my system (.yaml file) to get this working. 
The command "openssl aes-256-cbc -K $encrypted_badc503f6449_key -iv $encrypted_badc503f6449_iv -in assets/server.key.enc -out assets/server.key -d" failed and exited with 1 during .
I really think Trailhead ought to point out that you're going to have troubles running through the module in Windows....

Hi, 

  In below code I am hard coding RW: and FW: in the loop to compare and replace please suggest me how to  user keywords. 

public static void processUpdate(list<Case> cseLst) {
        String FWSubject;
        String RWSubject;
        String CaseSubject;
        list<Case> caseLst = new list<Case>();
       
        for (Case c : cseLst) {       
            if(c.subject <> null){     
                // Remove FW and RW from case subject to get exact string
                if(c.subject.Contains('FW:')){
                    FWSubject = c.subject.replaceAll('FW:','');
                    System.debug('FQ Trim String :' + FWSubject);
                    CaseSubject = FWSubject;     
                } else if(c.subject.Contains('RW:')){ 
                    RWSubject = c.subject.replaceAll('RW:','');
                    System.debug('RW Trim String :' + RWSubject);   
                    CaseSubject = RWSubject;

   }
}

Thanks
