PBEWithMD5AndDES

[Christine Davis]

Hello everyone,

 

I’m entering the brave new world (for me) of encrypting and sharing data 
between a couple of different applications.  We are attempting to encrypt a 
password using PBEWithMD5AndDES.  The Java Developer sent me the following 
information:

 

If cleartext (password) is nations1

then PBE encrypted is …÷     ‰Yu5+Tpô?__ E

and Base64 encoded is hfcJiVl1NStUcPQ/EBwgRQ== **

** This (Base64) is the value to store in the external_password field of 
correspondence_recipient.

 

For the example, we’re using C1F9J9V5 for the password and IVorSalt thing and 
iterations are as follows in Java:

 

byte[] salt = {

                    (byte)0xc7, (byte)0x73, (byte)0x21, (byte)0x8c,

                    (byte)0x7e, (byte)0xc8, (byte)0xee, (byte)0x99

                };

                int count = 20;

 

 

We’ve gotten this far:

 

<cfscript>

      theEncrytString = "nations1";

      thePassword = "C1F9J9V5";

      theMethod = "PBEWithMD5AndDES";

      theEncoding = "Base64";

      theSalt = "???????";  //WHAT IS THIS???? HOW DO WE DO IT???

      theIterations = 20;

      test = Encrypt(theEncrytString, thePassword, theMethod, theEncoding);

      //test = Encrypt(theEncrytString, thePassword, theMethod, theEncoding, 
theSalt, theIterations);

</cfscript>

<cfoutput>#test#</cfoutput>

 

Could someone please explain the IVorSalt variable, the Java code above that 
generates the salt byte array and what iterations are used for?  Also, I 
believe we need to recreate the Java code in ColdFusion for this to be shared 
between the two apps, how do we do that?

 

Thanks!
