## Signed options example
Here is an example with signed options through each step.
Using the github codercat, our image url is `https://octodex.github.com/images/codercat.jpg` and our options are `400x400` and `q40`.
The signature key is `secretkey`
The value that goes into the Digest is `https://octodex.github.com/images/codercat.jpg#400x400,q40`
and our resulting signed key is `0sR2kjyfiF1RQRj4Jm2fFa3_6SDFqdAaDEmy1oD2U-4=`
The final url would be
`http://localhost:8080/400x400,q40,s0sR2kjyfiF1RQRj4Jm2fFa3_6SDFqdAaDEmy1oD2U-4=/https://octodex.github.com/images/codercat.jpg`
## Language Examples
Here are examples of calculating signatures in a variety of languages. These
