# oc mint sample

this is a C++ implementation of the opencoin protocol 
as mapping to some kind of REST interface 

actually it 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)

## TODO

+ [x] bigint type for big integers encoded as string
+ [ ] blinding utilizing crypto++
- [x] complete from_json conversions
- [x] complete tests
- [x] drone config
- [ ] select crypto library
   + https://en.wikipedia.org/wiki/Comparison_of_cryptography_libraries
