    or 
    
-    python rsa.py

 ## generating keys
 to generate a key pair with and ID 
 
     ./rsa.py gen [keysize] [keyID]
-All generated keys are {working dir}/saves/ in keys folder
+All generated keys are saved in {$working_dir}/saves/
 ## encrypting 
 
     ./rsa.py encrypt "[message]" [RecieverKeyID] [SenderSignetureKeyID]
+## decrypting
+Assuming the encrypted message is encrypted to myPrivateKey
+    
+    ./rsa.py decrypt "[cipher]" [myPrivateKeyID]
+The signature is checked with all public keys stored in keys directory
