Keypairoom
Component to generate and regenerate a keypair, in a deterministic and private way. The cryptographic part consists of two Zenroom smart contracts, the first executed server-side to generate a seed (based on public data such as user name), the second generate client side, based on the output of the first smart contract and on private information, namely "The challenges".

Smart contracts deployed as APIs
See here what the scripts will return:
Client side: generation of keypair and optional hashing of challenges
And here the Swagger for both scripts (search for the names of the APIs on the page)
The deployment is done via restroom-mw and can be installed using the script deployAPI.sh or the Dockerfile, info about Dockerfile deployment here.
