[asterisk-users] How can I decipher password in SIP Packet?

I am receiving requests to register to my Asterisk extensions. I have the
full SIP packets. I also do see what extension is being tried to be
registered. Is there ANY WAY to know what password is being attempted?

I think the appropriate term would be decode the base64 response I get from
the client. Here is what I get in the SIP packet from the client:
*
*
 *Authorization: Digest username="4456678", realm="asterisk",
nonce="67461340", uri="sip:mailbox",
response="5a9a5f2b527ca9687c8f75705e6a2d25", algorithm=MD5*

Using a base64 decoder I get this:* *å¯Zåý›çnÜkÞ¼íÏ ïžôåîšÙݹ from the
"response" above. Of course, that is not the plain password. So, is that
encrypted? How can I can I decrypt it?

Thanks,
