In addition to the 1st amendment problems of banning certain kinds of code, I think forcing encryption to have a backdoor could be construed as part of a search, and so run afoul of the 4th amendment. Who knows what the courts might say though - I wonder if there's any precedent...

The 4th does state that it is "The right of the people to be secure in their [...] papers [...]." I'd love to witness a judicial argument that seeks to extend this to code/binary 'goods.'
