+Onetimebluh (Workbluhp in blogress!!)
+======================================
+
+Simple implementation of One Time Pad cipher.
+Capable of generating cryptographically strong random number keys and of usign them to encrypt/decrypt messages of same length with a bitwise XOR function.
+
+Usage
+-------
+
+Example creates two keys of lenght 4096 bytes and use the first as a message and the second as the pad key (just for testing):
+
+```
+onetimebluh --key-gen --nbytes 4096 --output message
+onetimebluh --key-gen --nbytes 4096 --output pad
+onetimebluh --encrypt message --key-file key --output encrypted-message
+onetimebluh --decrypt encrypted-message --key-file key --outptut decrypted-message
+```
+
+You can print the help by running `onetimebluh --help` or `onetimebluh -h`.
+
+```
