[Kaliber]

Well...okay:

Код:

if(!params[0])

Thats checks the NULL Byte..so when \0 is at the cell 0..the string is empty

Код:

if(!(2 < strlen(params) < 16))

That checks the string length...should be obvious

Then just read the tutorial

You open the file with Yini and set the password

Thats no magic at all
