miniproto.crypto.native.xor_bytes

xor_bytes(left: bytes, right: bytes) -> bytes

Return the byte-wise XOR of equal-length inputs.

Parameters:

• left (bytes) – First byte string.
• right (bytes) – Second byte string of the same length.

Returns:

• bytes – A byte string of that shared length.

Raises:

• ValueError – If the input lengths differ.

The public wrapper uses the fallback big-integer implementation because it wins the benchmarked handshake-sized cases; it offers no secret-zeroization.
