your right im using the code from that URL..

i have basically 2 phases

1.desktop for encrypting (encrypting and decrypting is working perfectly
fine in win32 desktop application using VC++ samples)
a.inituser
b.encrypt from command line
c.decrypt from command line

2.pocket pc for decrypting..

but when i try to decrypt the encoded file from the pocket pc using the same
RC4 stream algorithm

i get the wrong output file

(instead of word "microsoft" im getting in some ascii characters)

i have used the inituser for initialising in desktop for storing and
generating
keys(Container)

but i couldnt find the same init user application for pocket pc

can i get one?

any thoughts on this will be a great help

Thanks
