AES anyone?

[Bedros Hanounik]

can you explain your idea of streaming?

I was thinking of passing a buffer (pointer) to the AES function (with mode and keys), along with the length. and the you get back the cipher data.

please remember that AES only processes data in increments of 16bytes. So, if you send 17 bytes, you'll get cipher data length of 32byte; and you need all the 32 bytes to decrypt. if you pass 127 bytes, you'll get back 128bytes.....etc.

so, it's important to keep track of the length of plain (original) data along with the cipher data, so we can trim the extras once we decipher it.
