hi,
when you print a cache description there's this "Additional Hint(s)" 'crypted' in rot13. You can print it crypted and you'll have the problem to decrypt the text "in the wild" (thats annoying). Or you may click on "decrypt" and print the page (+put it in your bag) without reading these lines accidentally. Not that easy.
I thought about how to make this easier. I tried to find an 'encrpytion' that prevents reading the text accidentally but allowing easy decryption.
See some examples:
A:
'yyoeul lfoiwn ds ttohnee cuancdheer 2a0 ms mfarlolm rtohcek '
B:
'si_nn_foin_eu_uoofn__tohne__effooufre_hhfa_zeezl___nfunto_tt_rfeneos'
You can't read it. But decryption is easy! :-)
A:
First read character 1, 3, 5, 7, 9... to the end, then restart with 2,4,6,8,... .
B:
Ignore character 1,3,5,7,9..., or just read 2,4,6,8,....
I think these two alternatives are better than rot13, and I'ld be happy to see one of them on geocache.com.
You can try out these two encryptions (and others) on these online tools (text in german):

Or go to the following link (in german) to read about some other ways:
