Inputs to install did-git-sign for an already-provisioned persona.

All fields are values the caller already has — there is no VTA bootstrap here. The function writes the config file, stores VTA credentials in the OS keyring, runs the relevant git config invocations, and updates the allowed_signers file.

The verifying_key is the Ed25519 public key (32 raw bytes) that signs the persona’s commits. It’s used in the allowed_signers entry; the caller is expected to have already derived it from the persona key material.

Fields

global: bool

true writes config to the user’s ~/.config/did-git-sign/, false writes a repo-local .did-git-sign.json.

did_key_id: String

The verification method id, e.g. did:webvh:.../persona#key-1.

vta_key_id: String

VTA key UUID for the persona’s signing key (stored in keyring so did-git-sign -Y sign can fetch the secret on demand).

credential_did: String

DID this binary authenticates to the VTA as. The persona admin DID minted during VTA provisioning is the right value here.

credential_private_key_mb: String

Multibase-encoded private key paired with credential_did.

vta_did: String

VTA’s own DID (e.g. did:webvh:.../vta).

vta_url: String

VTA service URL, as resolved from the VTA’s DID document. May be empty for DIDComm-only VTAs — mediator_did must be set in that case so the signer can reach the VTA over DIDComm.

mediator_did: Option<String>

DIDComm mediator DID advertised by the VTA. When Some, the signer uses DIDComm transport instead of REST. Required when vta_url is empty.

user_name: Option<String>

Optional git config user.name to set during install.

verifying_key: &'a [u8; 32]

Persona signing key public bytes (Ed25519, 32 bytes).
