py-factom-did

py-factom-did is a Python library for working with DIDs on the Factom blockchain. It is an implementation of the Factom DID method specification and consists of two main modules: factom_did.client and factom_did.resolver.

The client module enables:

• creation of a new DID
• addition of management key(s) for the DID
• addition of DID key(s) for the DID
• addition of service(s) for the DID
• export of public metadata to be recorded on Factom
• encryption of the newly created keys
• update of an existing DID: adding/revoking management keys, DID keys and services and producing a signed DID update entry
• upgrade of the method version of an existing DID
• deactivaiton of an existing DID

The resolver module contains a pure-data library for re-constructing the effective DID Document from a list of DID entries. It is a complete implementation of the resolver specification in https://github.com/bi-foundation/FIS/blob/feature/DID/FIS/DID.md and contains an extensive unit test suite with 100% test coverage.

Examples

You can find an example of the library workflow in the examples/ directory. In order to run the example, please note that it is necessary to:

• have local instances of factomd and factom-walletd running
• create an environment variable called EC_ADDR, which contains a funded EC address to pay the fees for recording the DID on-chain
