Account storage support: authentication, revocation

• https://askubuntu.com/a/14536
• Storage per currency, per account name
• $XDG_DATA_HOME|$HOME/.local/share/silkaj/${currency}
  • ${account_name}: defined by the user, passed via general/specific option -a/--account
    • revocation.txt
    • authentication_file_${format}.json: Silkaj would discover which format is it, v1 formats will be dropped at some point

Implementation

Account storage

• Introduce global -a/--account option
• Storage class into silkaj/storage.py with tests tests/units/test_storage.py

Authentication

Read from --auth-* method, store into account storage:

silkaj  --account <account> authentication --auth-*

Need special handling of --auth-* and --account options separately in the authentication selection handling for the authentication command. Other commands using the authentication should read only from --account. The authentication command is kind of a converter command from --auth-* methods to account storage.

Use authentication command as an importer from scattered files to this account storage structure

• Move --auth-* options as authentication specific options?
  • Con: Would no longer allow easy authentication on other commands
  • Pro: Would force more secure account storage usage, conversion
• Set authentication methods as MutuallyExclusive
• Implementation in authentication command to store in the account storage
• Support a better default authentication file format creation in the storage than seedhex?
  • Implement (E)WIF authfile saving #173 (closed)
• Discover which authfile format it is: v1 (seedhex, pubsec), v2 (encrypted json)
  • authentication_file_ed25519.txt, authentication_file_sr25519.json
• Write tests

Revocation

# read auth file, write revocation file
silkaj --account <account> wot revocation create

# read revocation file
silkaj --account <account> wot revocation {verify,publish}

• create read authfile from --account and write revocation file into --account
• verify/publish: consume file from general --account option
• Write tests

Importer command?

• account import
• import already generated auth and revocation files to an account?

New Account label

• replace Storage label

Documentation

• Write documentation how this works (input as general option, output as command-specific option)
• Update README.md§Features with Account (storage) and Authentication methods.

account commands

• account list command

    def list(self):
        for root, dirnames, filenames in self.path.parent.walk():       
            print(root, dirnames, filenames)

• list available accounts per currencies: there contents, auth file, revocation file
• following implementations can all be done with Unix commands. To be done in a follow-up ticket?
• instead of a copy to the right place?
• account remove $account: remove complete account, remove only authentication or revocation file?
• account rename $old_name $new_name
