Detailed Description

Structure representing a resident/discoverable credential.

Represents a FIDO2 resident key (discoverable credential) that is stored on the authenticator and can be discovered without providing a credential ID.

Field Documentation

◆ alg

uint32_t sk_resident_key::alg

Cryptographic algorithm identifier for this key.

SSH_SK_ECDSA (0x00): ECDSA with P-256 curve SSH_SK_ED25519 (0x01): Ed25519 signature algorithm

◆ application

char* sk_resident_key::application

Relying Party (application) identifier string.

The RP ID (typically a domain name) that this resident key is associated with. Determines which application/service this key can be used for.

◆ flags

uint8_t sk_resident_key::flags

Flags associated with this resident key.

SSH_SK_USER_PRESENCE_REQD: Requires user presence for operations SSH_SK_USER_VERIFICATION_REQD: Requires user verification (PIN/biometric)

◆ key

struct sk_enroll_response sk_resident_key::key

Embedded enrollment response containing key material.

Contains the same data as returned during initial enrollment, including public key, key handle, and associated metadata.

◆ slot

size_t sk_resident_key::slot

Slot/index number of this key on the authenticator.

Zero-based index indicating the position of this resident key in the authenticator's internal storage. Used for key management and identification when multiple resident keys exist.

◆ user_id

uint8_t* sk_resident_key::user_id

User identifier associated with this resident key.

Binary user ID that was provided during key enrollment. Used to identify which user account this key belongs to.

◆ user_id_len

size_t sk_resident_key::user_id_len

Length of user_id buffer in bytes.

Length of the user identifier.
