g The bank from home work 5 recently hired a new developer. They are a C programer who hates python and wanted to rewrite the entire codebase. But they only succeeded in rewriting some of the code. Specifically, bankRecieveDeposit is now written in C and the deposit object is no longer a pickled python object. Instead it's a null terminated string of the form source;dest;amount. The encryption/decryption algorithms have not changed. I. e. it is still encrypted by XORing in a key stream derived using public key cryptography. The new programmer has the code running on a web server. Now anyone can submit deposits over the internet. The server will not respond with the contents of a submitted deposit. In fact, it seems it won't actually do anything at all with the deposit after decrypting it. But for some reason, for any submitted deposit, the server will respond with the result of strlen(PKDec(bankSK, CT)). I. e. the length of the decrypted string containing the deposit. How can you use this to learn the contents of an encrypted deposit
