Generate Sample Crypto Material

Metalo has a command that generates a new set of various data shapes used in MetaLocker, such as keys, key pairs, identities, passphrases, etc.

metalo sample-crypto

The following structures are generated:

  • sampleAESKeyBase64 - a Base64 encoded AES key
  • sampleApiKeys - a key/secret pait that can be used in MetaLocker’s configuration file, apiKeys section
  • sampleAssetID - a new asset ID
  • sampleEd25519Key - an Ed25519 key pair in Base64 encoding
  • sampleIdentity - a sample identity with one unilocker
  • samplePassphrase - a sample passphrase with a double SHA256 hash. It’s useful for generating account passwords using direct calls to MetaLocker API.

Sample output:

Generate New Asset

You may generate a new asset ID using new-asset command

Examples 

# generate new random asset ID
metalo new asset

# generate asset ID for the given file
metalo new asset <path-to-file>
