-Encrypt a file using a block cipher in CBC mode. Compresses the plaintext
-with Zlib, MACs with HMAC(SHA-1). Stores the block cipher used in the file,
-so you don't have to specify it when decrypting.
-
-What a real application would do (and what this example should do), is test for
-the presence of the Zlib module, and use it only if it's available. Then add
-some marker to the stream so the other side knows whether or not the plaintext
-was compressed. Bonus points for supporting multiple compression schemes.
-
-Another flaw is that is stores the entire ciphertext in memory, so if the file
-you're encrypting is 1 Gb... you better have a lot of RAM.
-
-Based on the base64 example, of all things
