Modify the encrypted version to not write down the rzip chunk size, then keep track of where each block header is written, go back and write 8 bytes of salt before it and encrypt the headers in place.

aes_crypt_cbc will allow you to work on the same buffer, so don't bother allocating a separate buffer.
Allocate slightly more on the buffer that might be used for encryption rather than reallocing.
