Generating Random Passwords to Different users.

Hai friends,

I explored on 'How to Generate Passwords Randomly for different users'.

In Apex , we have Crypto class to support encrypt and decrypt mechanism.

Here is the simple logic to generate AES key using crypto class . This key usually uses to encrypt and decrypt the data .

                           Blob blobKey = crypto.generateAesKey(128);

                           String key = EncodingUtil.convertToHex(blobKey);

                           System.debug(key);

Below is the code to generate AES key and sending email to entered email address . 

Controller:-

  public class PasswordGenerator 

{

        public String comments { get; set; }

        public String EmployeeNumber { get; set; }

        public String company { get; set; }

        public String Qualification { get; set; }

        public String Email { get; set; }

        public String Name { get; set; }

         string strPassword ='';

       public List<SelectOption> getQual() {

        List<SelectOption> options = new List<SelectOption>();

       options.add(new SelectOption('--NONE--','------NONE-----'));

        options.add(new SelectOption('MBA','MBA'));

        options.add(new SelectOption('MCA','MCA'));

        options.add(new SelectOption('DEGREE','DEGREE'));

        options.add(new SelectOption('INTER','INTER'));

        options.add(new SelectOption('SCHOOLING','SCHOOLING'));

        return options;

        }

    public static String getPassword(Integer len)

     {

        Blob blobKey = crypto.generateAesKey(128);

        String key = EncodingUtil.convertToHex(blobKey);

        System.debug(key);

        return key.substring(0,len);

     }

    

     public pagereference save()

      {

        String password =PasswordGenerator.getPassword(12);

        Blog_Members__c obj=new Blog_Members__c();

        obj.Name=Name;

        obj.company__c=company ;

        obj.Email__c=Email;

        obj.Employee_Number__c=EmployeeNumber ;

        obj.Comments__c=comments;

        obj.Qualification__c=Qualification ;    

        obj.Password__c = password;

        insert obj;

        sendpassword(Email,password);

         ApexPages.addMessage(new ApexPages.Message(ApexPages.Severity.INFO, 'Login Details has been mail to your Registered mail Address .')); 

         company ='';

         Qualification ='';

         EmployeeNumber ='';

         comments ='';

         Email ='';

         Name ='';

         return null; 

      }

      

      public void sendpassword(String Email,String Password)

      {

        Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();

        String[] toAddresses = new String[]{Email}; 

        String[] ccAddresses = new String[] {'haribabu.amudalapalli@gmail.com'};

        String Password1 =Password;

        System.debug('hari Testing'+Password1+'Email address'+toAddresses );

        mail.setToAddresses(toAddresses);

        mail.setCcAddresses(ccAddresses);

        mail.setReplyTo('support@acme.com');

        mail.setSenderDisplayName('Salesforce Blog ');

        mail.setSubject('Pass Word From Salesforce Blog');

        mail.setBccSender(false);

        mail.setUseSignature(false);

        mail.setPlainTextBody('Your UserName: ' + Email +';/n Pass Word '+Password1 );

        mail.setHtmlBody('Your UserName: ' + Email +'\n Pass Word '+Password1);

        Messaging.sendEmail(new Messaging.SingleEmailMessage[] { mail });     

      } 

  }

Check this once.It's working fine.
