UNIVERSITY OF TECHNOLOGY SYDNEYYou extracted some images from some network traffic: A$5$cbcImages.zip Download A$5$cbcImages.zip. One image contained a base$64$ blob of some ciphertext in the metadata.

You were also given two values:

$1.$ d$5$c$25$cc$61$ce$78139$a$545$e$22$c$7$d$220$d$84$

$2.$ H$+$xoK$8/$xdac$4$YgHtWyN$/$YQ$==$

Research AES$-$CBC to determine what these values represent, and thus how they can be used in the decryption process.

$($Hint: one is the hash of the encryption key, and the other is the base$64$ of IV$).$ Find the encryption key.
