I was testing abcrypt, I noticed that when encrypting a large video file of size like 4GB consumed more than 7GB of RAM.

It would be nice if the data is fetched, encrypted, and saved in the output file block by block (like 1MB, or 100MB) so this way the RAM usage will be limited to max 2 Blocks. For example, if the the chosen block size is 10MB then 10MB will be read from the plaintext file and encrypted into cyphertext of around 10MB hence, total of 20MB will be used.

I think it may be possible to solve this issue by implementing traits such as Read and Write.
