-A simple example of using wolfSSL to sign and verify binary data using SHA512 and ECC256.
+A simple example of using wolfSSL to sign and verify binary data. It supports RSA and ECC for signing and MD2, MD4, MD5, SHA, SHA256, SHA384 and SHA512.
 
-This example creates a signature from a hash of the file and signs it using a generated ECC key. Then it performs a verification using the signature and public key. 
+This example creates a signature from a hash of the file and signs it using a generated key. Then it performs a verification using the signature and public key.
 
 
 ## Compiling and Running the Example
 
 ```
 $ make
-$ ./firmware [filename]
+$ ./firmware [filename] [sig] [hash]
 ```
+
+## Usage
+
+Usage: signature <filename> <sig> <hash>
+  <sig>: 1=ECC (def), 2=RSA
+  <hash>: 1=MD2, 2=MD4, 3=MD5, 4=SHA, 5=SHA256 (def), 6=SHA384, 7=SHA512, 8=MD5+SHA
