Repeating symbols in the middle, plus the complexity of the outer sections suggests (to me at least) that there is more than just a key here. Ignoring the symbols (which look a little like bastardized geometry notations) and breaking the hex into words:
F0 BE 58 F2 FD 63
6C 79 D2 E4 93 E6
... to decimal is...
240 190 88 242 253 99
108 121 210 228 147 230
...or binary...
111100001011111001011000111100101111110101100011
11011000111100111010010111001001001001111100110
Taking each symbol/value individually:
111100001011111001011000111100101111110101100011
011011000111100111010010111001001001001111100110
...the length of which is divisible by three, curiously...
111 100 001 011 111 001 011 000 111 100 101 111 110 101 100 011
011 011 000 111 100 111 010 010 111 001 001 001 001 111 100 110
...or in decimal...
7 4 1 3 7 1 3 0 7 4 5 7 6 5 4 3
3 3 0 7 4 7 2 2 7 1 1 1 1 7 4 6
The first section seemed to decode via base three. So converting the values produces:
f 0 b e 5 8 f 2 f d 6 3
6 c 7 9 d 2 e 4 9 3 e 6
122 000 102 121 012 022 122 002 122 111 020 010
020 110 021 100 111 020 121 011 100 010 121 020
Using the mapping in the first paragraph doesn't seem to make any sense:
RALQFI... or Q KPEH...
Who's to say I'm on the right track here, but if I am, I think a new mapping is required.
