+### DGST Sign and Verify
+
+The commands below sign this README then verify it with the resulting signature.
+```
+wolfssl dgst -sha256 -sign mykey.priv -out readme.sig ./README.md
+wolfssl dgst -sha256 -verify mykey.pub -signature readme.sig ./README.md
 ```
 
-### X509
-
-```
-wolfssl -x509 -inform pem -in certs/ca-cert.pem -outform der -out outputfilename.der
-wolfssl -x509 -inform der -in certs/ca-cert.der -outform pem -out outputfilename.pem
-```
-
-### RSA Signature Generation and Verification
-
-#### Hash
-
-```
-wolfssl -hash sha256 -in README.md -out README.md.sha256
-```
-
-#### Sign
-
-```
-wolfssl -rsa -sign -inkey ../certs/client-key.der -in README.md.sha256  -out README.md.signed
-```
-
-#### Verify
-
-```
-wolfssl -rsa -verify -inkey ../certs/client-keyPub.der -sigfile README.md.signed -out README.md.verify -pubin
-```
-
-At this point, the contents of `README.md.sha256` and `README.md.verify` should be the same.
