I would like to be able to crypt certain words of a file. For example here is my file
java~c++~java~java~java~java
java~c++~java~java~java~java
java~c++~java~java~java~java
java~c++~java~java~java~java
java~c++~java~java~java~java
all I want to crypt is "c++" .... and the rest of the file stays the same
Is there a possiblilly to to this .......

hmm, going to need more info than this I think. Is it a text file? Is it a file you write or just read? Do you need to encrypt it or just make it non human legible? Is it always going to be the same thing (like c++ on every line)or is it something different for each line?
Need some more info/answers/explanations before we can take a shot at helping you with this.

Parse the String, Tokenize it on c++, encrypt the tokens(using one of the encryption algorithms, i would suggest using the LZW) and reset the tokens in their original places.
Thats it, you are done.
