Open Attestation (CLI)

This CLI tool in the Open Attestation CLI repository turns .json documents into any open-attestation verifiable documents. It applies the OpenAttestation algorithm to produce a hash of the json document and then creates a file with the data and proof of integrity.

Installation

Binary

To install the binary, simply download the binary from the CLI release page for your OS.

We are aware that the size of the binaries must be reduced and we have tracked the issue in Github. We hope to find a solution in a near future and any help is welcomed.

NPM

Alternatively for Linux or MacOS users, if you have npm installed on your machine, you may install the cli using the following command:

npm install -g @govtechsg/open-attestation-cli

The above command will install the open-attestation CLI to your machine. You will need to have node.js installed to be able to run the command.

You can also opt to use npx:

npx -p @govtechsg/open-attestation-cli open-attestation <arguments>

In all the guides, we will refer to the CLI as open-attestation when running a command. That means we will assume the CLI is available in your execution path. If it's not the case, you will to change open-attestation by the full path to the executable.

Wrapping documents

This command process all documents in the input directory. It will add the issuance proofs to the individual documents. Additionally, you'll get the Batch Document Root (merkleRoot) value. Thereafter, you can issue all the documents in a single batch with the merkleRoot later.

Example:

open-attestation wrap ./examples/raw-documents/example.0.json

✔  success  Batch Document Root: 0xf51030c5751a646284c898cff0f9d833c64a50d6f307b61f2c96c3c838b13bfc

The command will display the result in the console. If you need to save the file you can use the --output-file file.

Example:

open-attestation wrap ./examples/raw-documents/example.0.json --output-file ./examples/wrapped-documents/example.0.json

✔  success   Batch Document Root: 0x5d318c8083aac18f8075ca2a2eac74b06f2cc37d6ccad680c7c80c9bb36f7be1

If you need to wrap a folder you will need to provide the --output-dir options to specify in which folder the documents must be wrapped in.

Example:

open-attestation wrap ./examples/raw-documents --output-dir ./examples/wrapped-documents

✔  success   Batch Document Root: 0x5d318c8083aac18f8075ca2a2eac74b06f2cc37d6ccad680c7c80c9bb36f7be1

You can also provide an optional JSON schema document to perform extra check on the documents

Example:

open-attestation wrap ./examples/raw-documents/ --output-dir ./examples/wrapped-documents/ --schema ./examples/schema.json

✔  success  Batch Document Root: 0xf51030c5751a646284c898cff0f9d833c64a50d6f307b61f2c96c3c838b13bfc

open-attestation wrap ./examples/raw-documents/ ./examples/wrapped-documents/ -s ./examples/schema.json

✔  success  Batch Document Root: 0xf51030c5751a646284c898cff0f9d833c64a50d6f307b61f2c96c3c838b13bfc

The JSON schema parameter also allow for http endpoint returning valid JSON schema:

Example:

open-attestation wrap ./examples/raw-documents/ --output-dir ./examples/wrapped-documents/ --schema https://gist.githubusercontent.com/Nebulis/dd8198ab76443489e14121dad225d351/raw/693b50a1694942fb3cc6a8dcf5187cc7c75adb58/schema.json

✔  success  Batch Document Root: 0xf51030c5751a646284c898cff0f9d833c64a50d6f307b61f2c96c3c838b13bfc

open-attestation wrap ./examples/raw-documents/ --output-dir ./examples/wrapped-documents/ -s https://gist.githubusercontent.com/Nebulis/dd8198ab76443489e14121dad225d351/raw/693b50a1694942fb3cc6a8dcf5187cc7c75adb58/schema.json

✔  success  Batch Document Root: 0xf51030c5751a646284c898cff0f9d833c64a50d6f307b61f2c96c3c838b13bfc

You can also re-wrap a document by editing a wrapped document content and using the --unwrap option:

open-attestation wrap ./examples/raw-documents/example.0.json --output-file ./examples/wrapped-documents/example.0.json

# edit the recipient name in ./tmp/wrapped-documents/example.0.json for instance for Your Name to Another Name
open-attestation wrap ./examples/wrapped-documents/example.0.json --of ./examples/wrapped-documents/example.1.json --unwrap

You can disable the --batched option to wrap multiple documents individually (i.e. they will not have the same merkle root):

open-attestation wrap ./examples/raw-documents/ --output-dir ./examples/wrapped-documents/ --batched false
✔  success   All documents have been individually wrapped

By default the CLI will use open-attestation schema v2 but you can opt in for open-attestation schema v3 using open-attestation-v3 option:

open-attestation wrap ./examples/raw-documents/ ./examples/wrapped-documents/ --open-attestation-v3
open-attestation wrap ./examples/raw-documents/ ./examples/wrapped-documents/ --oav3

NOTE: For transferable records, you should wrap them individually as each of them would be minted to a unique title escrow that represents the beneficiary and holder entities of the document. For more information about title escrow, refer here.

Unwrapping documents

This command processes a document in the input directory. It will unwrap the wrapped document to its raw document form to be displayed on the console.

Example:

open-attestation unwrap ./examples/v2/wrapped-documents/example.0.json

✔  success   The document has been unwrapped

The command will display the result in the console. If you need to save the file you can use the --output-file option.

Example:

open-attestation unwrap ./examples/v2/wrapped-documents/example.0.json --output-file ./examples/v2/raw-documents/example.0.json

✔  success   The document has been unwrapped

If you need to unwrap a folder you will need to provide the --output-dir option to specify which folder the documents must be unwrapped in.

Example:

open-attestation unwrap ./examples/v2/wrapped-documents --output-dir ./examples/v2/raw-documents

✔  success   The documents have been individually unwrapped into folder ./examples/v2/raw-documents

Document privacy filter

This allows document holders to generate valid documents which obfuscates certain fields. For example, sensitive information that you wish not to disclose.

open-attestation filter <inputDocumentPath> <outputDocumentPath> [filters...]

Example:

open-attestation filter examples/wrapped-documents/example.0.json tmp/example.0.out.json key1

✔  success  Obfuscated document saved to: tmp/example.0.out.json

Encrypting document

This allows you to encrypt document in order to share and store them safely.

open-attestation encrypt <inputDocumentPath> <outputEncryptedPath>

Example:

open-attestation encrypt ./examples/wrapped-documents/example.0.json ./tmp/encrypted.json

✔  success   Encrypted document saved to: tmp/encrypted.json
⚠  warning   Here is the key to decrypt the document: don't lose it: 9bac5be27bac31d852fc1e48eb9d5249ec6ad7978da23377b5879f7a24994cb2

Decrypting document

This allows you to decrypt document encrypted using the method above.

open-attestation decrypt <input> <output> <key>

Example:

open-attestation decrypt ./src/__tests__/fixture/did-dns-encrypted.json decrypted.json 88da9b9cd61cfc1677ae7e79dba9b3aeba4b40c95f94c950759e76c6210b5402

- private key ....

Providing the wallet

When interacting with blockchain you will likely need to provide a way to access your wallet. All functions - when the wallet is required - will provide multiples ways for you to pass it in:

  1. Using encrypted-wallet-path option where you provide a path to an encrypted wallet (recommended).
  2. Using OA_PRIVATE_KEY environment variable holding the private key.
  3. Using --key-file option where you provide a path to a file containing the private key.
  4. Using --key option where you provide the private key directly to the command (Note that in this case, the private key may be stored in the machine's bash history).

Example:

# Using encrypted-wallet-path option
open-attestation deploy document-store "My Name" --network ropsten --encrypted-wallet-path /path/to/wallet.json
# Then you will be prompted to type your password to decrypt the wallet
? Wallet password [input is hidden]

# Using environment variable
export OA_PRIVATE_KEY=0000000000000000000000000000000000000000000000000000000000000001
open-attestation deploy document-store "My Name" --network ropsten
unset OA_PRIVATE_KEY

# Using private key stored in file
echo -n 0000000000000000000000000000000000000000000000000000000000000002 >> ./examples/sample-key
open-attestation deploy document-store "My Name" --network ropsten --key-file ./examples/sample-key
rm ./examples/sample-key

# Providing the key to the command
open-attestation deploy document-store "My Name" --network ropsten --key 0000000000000000000000000000000000000000000000000000000000000003

Config (Create configuration file)

This command will generate a config file with sandbox DNS, document store and token registry.

Please note that a wallet.json file in ropsten network with sufficient funds must be provided in order for this command to work.

You will need:

  • --output-dir option specify which folder the config file will be created in.
  • --encrypted-wallet-path option indicates a path to an encrypted wallet.
  • --config-template-url option to provide a path to reference a config template file hosted on a public url.
  • --config-template-path option to provide a path to reference a config template file locally.

There are 2 ways of using this command to generate a config file, both in which, will return a new config file with sandbox DNS, updated document store and updated token registry.

Method 1: Using config-template-url option (recommended)

This method will generate the most basic config file with a sandbox DNS, document store and token registry. The reference config templates are here.

Step 1: Generate a wallet.json file

// If you already have a wallet.json that is in ropsten network with sufficient funds, you can skip this step.
open-attestation wallet create --output-file wallet.json --fund ropsten

Step 2: Generate config file by passing in the generated wallet.json file

open-attestation config create --output-dir ./example-configs --encrypted-wallet-path </path/to>/wallet.json --config-template-url <remote url>

Method 2: Using config-template-path option

This method will generate a copy of your existing config file with the updated sandbox DNS, document store and token registry.

Step 1: Generate a wallet.json file

// If you already have a wallet.json that is in ropsten network with sufficient funds, you can skip this step.
open-attestation wallet create --output-file wallet.json --fund ropsten

Step 2: Generate config file by passing in the generated wallet.json file and a existing config file

open-attestation config create --output-dir ./example-configs --encrypted-wallet-path </path/to>/wallet.json --config-template-path </path/to>/config.json

Cancel pending transaction

This command will cancel pending transaction.

Please note that a this action is irreversible.

You will need:

  • --nonce option specify which transaction to cancel.
  • --gas-price option, the gas price is required to be higher than the pending transaction.
  • --transaction-hash transaction hash option can be used as an alternative to nonce and gas-price option. Using this option will automatically increase the transaction gas price by 100%.
  • options to provide the wallet (https://github.com/Open-Attestation/open-attestation-cli#providing-the-wallet)
open-attestation transaction cancel --nonce <pending transaction nonce> --gas-price <gas price> [option]

Examples:

open-attestation transaction cancel --nonce 1 --gas-price 300 --network ropsten --encrypted-wallet-path /path/to/wallet

open-attestation transaction cancel --transaction-hash 0x000 --network ropsten --encrypted-wallet-path /path/to/wallet

Title Escrow

Change Holder

This command will allow the owner of a transferable record to change its holder.

open-attestation title-escrow change-holder --token-registry <TOKEN_REGISTRY_ADDRESS> --tokenId <TOKEN_ID> --to <TO> [options]

Example - with private key set in OA_PRIVATE_KEY environment variable (recommended). More options.

open-attestation title-escrow change-holder --token-registry 0x4933e30eF8A083f49d14759b2eafC94E56F0b3A7 --tokenId 0x951b39bcaddc0e8882883db48ca258ca35ccb01fee328355f0dfda1ff9be9990 --to 0xB26B4941941C51a4885E5B7D3A1B861E54405f90

✔  success   Transferable record with hash 0x951b39bcaddc0e8882883db48ca258ca35ccb01fee328355f0dfda1ff9be9990's holder has been successfully changed to holder with address: 0xB26B4941941C51a4885E5B7D3A1B861E54405f90
