Under the anticircumvention clause of the DMCA, if I xor every 7th byte of 8 byte blocks with the value in the 8th, and you figure that out, and then wrote a program that (un)did the xor, you'd be in violation of the DMCA. Doesn't matter outside of that, the law is poorly written, any means or attempt to break the circumvention is a violation.
