xorstream

Utility for transforming an input stream to an output stream with a bytewise xor transform applied.

As an installed executable, takes a vector of 4, 5, or 6 bit wide (hex, 32, 64) which then pipes from stdin to stdout.

As a dependency it exposes a Transformer and a XorIter or XorStream. Transformer takes a vector of bytes and an impl Read. The Transformer implements IntoIter or IntoStream depending on features = [ "std" ] or features = [ "stream" ].

Installing with x86_64-unknown-linux-musl (for example) can increase the rate it occurs greatly.

shell $ cargo install xorstream --features bin --target x86_64-unknown-linux-musl

Example:

shell $ yes 0 | cargo run --features bin --release --target x86_64-unknown-linux-musl -- -4 714b

This pipes AAAAAAAAAAAAAAAAAAAAA infinitely to stdout, using std xorstream.
