Store a private key in Azure Key Vault​

Register Web3Signer as an application and add a signing key in Azure Key Vault.

Take note of the following to specify when configuring the signing key configuration file or bulk loading signing keys:

  • Vault name, which is part of the URL (for example https://<vaultname>.vault.azure.net).
  • Client credentials, which can include:
    • Client ID
    • Client secret
    • Tenant ID
note

Depending on the authentication mode, not all client credentials are available.

  • Key name, which is the name of the secret.
