Client support for Blockstack

• Currently only OI Chat supports this type of authentication.
• Client apps need to write a file mxid.json into the root of their gaia bucket. The content is the challenge received from a home server auth endpoint. Then for authentication, the client needs to send the id address as username and as password a client app generated nonce that was used when requesting the challenge together with the app domain in the format nonce + "|" + appDomain + "|" + blockstackId . Users can do this manually on a account management site.

Client support for EOS

• Currently only Diri Chat supports this type of authentication.
• Client apps need to sign the following message: ${account.name} would like to login using the ${account.authority} permission. Block ID: ${chainInfo.last_irreversible_block_num} ${chainInfo.last_irreversible_block_id.slice(-12).toUpperCase()} Then for authentication, the client needs to send the account name as username and as password a client app generated nonce that was used when requesting the challenge together with the message and signature in the format nonce + "|" + message + "|" + signature .
