Detailed Description

FIDO2/U2F security key callbacks structure.

This structure contains callbacks for FIDO2/U2F operations. It allows applications to provide custom implementations of FIDO2/U2F operations to override the default libfido2-based implementation.

Warning: These callbacks will only be called if libssh was built with FIDO2/U2F support enabled. (WITH_FIDO2 = ON).

Field Documentation

◆ api_version

sk_api_version_callback ssh_sk_callbacks_struct::api_version

This callback returns the SK API version used by the callback implementation.

See also: sk_api_version_callback for detailed documentation

◆ enroll

sk_enroll_callback ssh_sk_callbacks_struct::enroll

This callback enrolls a new FIDO2/U2F credential, generating a new key pair and optionally storing it on the device itself (resident keys).

See also: sk_enroll_callback for detailed documentation

◆ load_resident_keys

sk_load_resident_keys_callback ssh_sk_callbacks_struct::load_resident_keys

This callback enumerates and loads all resident keys (discoverable credentials) stored on the FIDO2 device.

See also: sk_load_resident_keys_callback for detailed documentation

◆ sign

sk_sign_callback ssh_sk_callbacks_struct::sign

This callback performs cryptographic signing operations using a previously enrolled FIDO2/U2F credential.

See also: sk_sign_callback for detailed documentation

◆ size

size_t ssh_sk_callbacks_struct::size

DON'T SET THIS use ssh_callbacks_init() instead.
