vault-plugin-icon

A HashiCorp Vault plugin that supports secp256k1 based signing, with an API interface that turns the vault into a software-based HSM device.

The plugin only exposes the following endpoints to enable the client to generate signing keys for the secp256k1 curve suitable for signing ICON transactions,
list existing signing keys by their names and addresses, and a /sign and /param_sign endpoint for each account.

It helps to generate and sign the private key in the Vault.
It never gives out the private keys.
