A friend of mine received this letter from guy she has known since she was little. She cant crack it and neither can I. Anyone know the key??

It might be Playfair encryption (described [Invalid or Expired Link Removed]). Far from unbreakable, but lacking the original keyword used by the author it would take even a skilled expert quite a while to decode it.

There may be some software available on the web that can crack it.
 
there's an f on line 13 position 3, just under one of the mistakes.

i don't see any 'z''s though. there also doesn't appear to be any 'm''s , although i could be mistaken. so this might be a playfair with i and j, and two e's. this leads me to think that the code word contains both a j and two e's, where each e is denoted differently.

is there a code word that might be appropriate to both the sender and receiver that has a j and two e's in it?

Yeah maybe something with her name?
 
.. my nesting was here

If that's the keyphrase, then the grid, assuming Playfair, would be:

M Y N E S
T I G W A
H R B C D
F K L O P
Q U V X Z

But I see no M, or Z or P either. And it's not always easy to distinguish C and L from each other. The two E's may be significant, or may be just a quirk of the guy's handwriting.

Found a JavaScript page where you can experiment with various alphabets and grids, according to the rules of classic Playfair (missing letter maps to I): Link Removed. If you have teh skillz you may edit the JS code to allow for other rules.

This thing may of course be some personal variation, but why should the guy have made it that difficult if he wanted it to be decoded at all?
 
heres the code in type if anyone wants to put it into programs to try to crack it. Im giving it a shot but havent been successful yet. Now im not sure weather the key to this is the phrase, "my nesting was here" or the answer to that phrase. Which in that case could be a town by the name of Naperville.

the last and 2nd line are common, but is it cs or ls?
