It seems Nothing in it's file.But I think "pywallt can ONLY Find which are encrypted key (litecoin),It can't Find out unencrpted key(litecoin)"

I creat a new wallet ,pywallet find nothing.but after encrypt wallet.pywallet woks well (+﹏+)~ It really confused me.

And my Officemate's wallet looks not encrypted,but 90112 byte... same as new_ encrypted_wallet 90112 byte

Useing Ultraedit find out

NEW wallet litecoin_wallet_encrypted

27 00 01 04 63 6B 65 79 21 ; '...ckey!

My Officemate's wallet litecoin_wallet_NOT_encrypted

26 00 01 03 6B 65 79 21 ; &...key!

NEW wallet litecoin_wallet_NOT_encrypted

26 00 01 03 6B 65 79 21 ; &...key!

- [ ] 5.I have no alternative,let the pywallet working on NOT_encrypted wallet ,Or other toolkit.Big thanks.
