Create a DID

While there exists many DIDs, this tutorial will focus only on ethr DID. At the moment, OpenAttestation only supports ethr DID.

The creation of an ethr DID is identical to the creation of a wallet, as it relies entirely on the Ethereum architecture.

  • If you already have a wallet, you can use the same one for this tutorial.
  • If you are going to revoke documents using document store, ensure that the wallet has sufficient balance.

Next, you will need to retrieve the wallet private key.

Running the wallet create command​

open-attestation wallet create --of wallet.json

The response looks like the following:

ℹ  info      Creating a new wallet
? Wallet password [hidden]
…  awaiting  Encrypting Wallet [====================] [100/100%]
ℹ  info      Wallet with public address 0xaCc51f664D647C9928196c4e33D46fd98FDaA91D successfully created. Find more details:
✔  success   Wallet successfully saved into /home/nebulis/IdeaProjects/open-attestation-cli/wallet.json

A wallet will be created in the current folder, in the wallet.json file.

Retrieving the private key​

Run the command:

 open-attestation wallet decrypt wallet.json

The response looks like the following:

⚠  warning   You are about to reveal the private key of your wallet. Please type "yes" (without quotes) into the terminal to prove that you understand the risks
? ack: yes
ℹ  info      User consented to risks
? Wallet password [hidden]
…  awaiting  Decrypting Wallet [====================] [100/100%]
ℹ  info      Wallet successfully decrypted
✔  success   Wallet information:
 - address: 0xaCc51f664D647C9928196c4e33D46fd98FDaA91D
 - public key: 0x041582ae06ae170b4c5610599c8a5fee37414da84f7e2a3b3c48789199c3202f2c7673f3e32dfead4543247ccb792aa4f54dbd3e701172723434e88f770dd64823
 - private key 0x7b227ac59116f3eeb2b265422cf3cbfbd244c525961fb297eb52153ec62aa845

There are two pieces of important information to keep for the next steps:

  • the wallet address (0xaCc51f664D647C9928196c4e33D46fd98FDaA91D in the example above)
  • the private key (0x7b227ac59116f3eeb2b265422cf3cbfbd244c525961fb297eb52153ec62aa845 in the example above)

Please note that you will definitely get different values.

Important: To make the tutorial easier to follow, it shows all the information about the wallet in use, including the private key. It is a throw-away wallet for that purpose. That means that this wallet can be never used again. You must NEVER SHARE THE PRIVATE KEY of your wallet.
