Crate fips_identity 

FIPS Identity System

Node identity based on Nostr keypairs (secp256k1). The node_addr is derived from the public key via SHA-256, and the FIPS address uses an IPv6-compatible format with the 0xfd prefix.

Structs

AuthChallenge

A 32-byte random authentication challenge.

AuthResponse

Response to an authentication challenge.

FipsAddress

128-bit FIPS address with IPv6-compatible format.

Identity

A FIPS node identity consisting of a keypair and derived identifiers.

NodeAddr

16-byte node identifier derived from truncated SHA-256(pubkey).

PeerIdentity

A known peer’s identity (public key only, no signing capability).

Enums

IdentityError

Errors that can occur in identity operations.

Constants

FIPS_ADDRESS_PREFIX

FIPS address prefix (IPv6 ULA range).

Functions

decode_secret

Decode a secret key from either nsec (bech32) or hex format.

encode_npub
