-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.

-  Grab an RSA public key from the file given as an argument, grab a message
-  from another file, and encrypt the message.
-
-  Algorithms used:
-    RSA with EME1(SHA-1) padding to encrypt the master key
-    CAST-128 in CBC mode with PKCS#7 padding to encrypt the message.
-    HMAC with SHA-1 is used to authenticate the message
-
-  The keys+IV used are derived from the master key (the thing that's encrypted
-  with RSA) using KDF2(SHA-1). The 3 outputs of KDF2 are parameterized by P,
-  where P is "CAST", "IV" or "MAC", in order to make each key/IV unique.
-
-  The format is:
-     1) First line is the master key, encrypted with the recipients public key
-        using EME1(SHA-1), and then base64 encoded.
-     2) Second line is the first 96 bits (12 bytes) of the HMAC(SHA-1) of
-        the _plaintext_
-     3) Following lines are base64 encoded ciphertext (CAST-128 as described),
