Chapter 2: Dealing with Binary and Random Data
When building solutions that leverage cryptography, we're almost always faced with two issues.
The first is managing binary data, which is a sequence of bytes, including characters that can't be represented as text. Most people have the experience of opening a binary file (such as an image and an executable application) in a text editor such as Notepad and being presented with a sequence of random, garbled symbols that can't be read, let alone edited.
In cryptography, encrypted messages, hashes, keys, and sometimes even decrypted messages are guaranteed to contain non-printable, binary data. This introduces challenges for developers as binary data often requires special handling to be visualized ...
