# opencoin issuer
|
|
|
|
this is a C++ implementation of the [opencoin protocol](https://opencoin.org/OpenCoin.html)
|
|
done as mapping to some kind of REST interface.
|
|
|
|
As all issuer related interactions of the protocol follows a request/response mechanism we are able to map all of them to Http-Requests.
|
|
|
|
We decided to use POST-Requests in all cases,
|
|
as the protocol uses JSON-formatted messages for requests.
|
|
|
|
The following table gives an overview of the mapping of requests to URLs:
|
|
|
|
| Request | URL | Response | C++ Interface Method |
|
|
|:------------------|:-------------|:------------------------------|:---------------------------------------------------|
|
|
| RequestCDDCSerial | /cddc/serial | ResponseCDDCSerial | cdd.cdd_serial of Model::getCurrentCDDC() |
|
|
| RequestCDDC | /cddc | ResponseCDDC | Model::getCurrentCDDC() |
|
|
| RequestMKCs | /mkcs | ResponseMKCs | Model::getMKCs |
|
|
| RequestMint | /mint | ResponseMint | Model::mint |
|
|
| RequestRenew | /renew | ResponseMint or ResponseDelay | ? |
|
|
| RequestResume | /resume | ResponseMint or ResponseDelay | ? |
|
|
| RequestRedeem | /redeem | ResponseRedeem | Model::redeem |
|
|
|
|
actually the implementation is a work in progress.

## Protocol Questions
|
|
|
|
+ What is signed as cdd - only the content of the cdd item with curly braces
|
|
or also the key?
|
|
+ the weighted URL as array has a different js encoding as other elements
|
|
+ Clarify PSS usage (see https://crypto.stackexchange.com/questions/12707/usability-of-padding-scheme-in-blinded-rsa-signature)
