  The OP message is made of ascii ordinals encoded in hexadecimal. That led me to some interesting ideas based on fooling your adversary into thinking they had cracked your code, when they had in fact missed a hidden message: 1/ In the above example the message was “one if by land two if by…” and the encoding base was hexadecimal. Does a message exist that encodes in a different base but looks like it is hexadecimal? For example the OP’s message decodes to utk"ol"h if the base was actually 17. We assume it’s base16 not base17 because only the digits 0-F are used. Is there a string of pairs of digits in the range 0-F (without G) that would decode to something meaningful in base 17 (0-G)? 2/ And what about a message that means two different things — something innocuous in base16, with the secret message in base17, say? Other bases might work: 15 feels like a good candidate too, but it is probably harder to make a readable message the more you deviate from the masquerade base.

    16 --> 15 would be a good candidate, as everyone would assume base 16 and you could use the full character set in your (secret) base 15 message. Too lazy to test it out, but theoretically plausible.
