+A fork of the dum^H^H^Hsimplest encryption tool in the world,

 # Usage
 
 Encrypt a file using a password:
 
 ```sh
-encpipe -e -p password -i inputfile -o outputfile
+tweetpipe -e -p password -i inputfile -o outputfile
 ```
 
 Decrypt a file using a password:
 
 ```sh
-encpipe -d -p password -i inputfile -o outputfile
+tweetpipe -d -p password -i inputfile -o outputfile
 ```
