Static Methods

convertBits(List<int> data, int from, int to, bool pad) → List<int>: Convert bits from one size to another Used for bech32 encoding/decoding
decode(String nip19String) → String: Decode a NIP-19 encoded string (npub, note, nevent, nprofile, naddr) Returns the decoded hex string
decodeNaddr(String naddrStr) → Naddr: Decode naddr and return Naddr object
decodeNevent(String neventStr) → Nevent: Decode nevent and return Nevent object
decodeNprofile(String nprofileStr) → Nprofile: Decode nprofile and return Nprofile object
encodeNaddr({required String identifier, required String pubkey, required int kind, List<String>? relays}) → String: Encode naddr (addressable event coordinate) identifier - the "d" tag value (empty string for normal replaceable events) pubkey - 32-byte hex public key of the event author (required) kind - event kind number (required) relays - optional list of relay URLs where the event may be found
encodeNevent({required String eventId, List<String>? relays, String? author, int? kind}) → String: Encode nevent (event reference) eventId - 32-byte hex event ID (required) relays - optional list of relay URLs where the event may be found author - optional 32-byte hex public key of the event author kind - optional event kind number
encodeNoteId(String id) → String: Encode a note ID as note1
encodeNprofile({required String pubkey, List<String>? relays}) → String: Encode nprofile (profile reference) pubkey - 32-byte hex public key (required) relays - optional list of relay URLs where the profile may be found
encodePrivateKey(String privateKey) → String: Encode a private key as nsec
encodePubKey(String pubkey) → String: Encode a public key as npub
encodeSimplePubKey(String pubKey) → String: Encode a public key in simplified format (first10:last10)
isKey(String hrp, String str) → bool: Check if a string starts with a specific HRP (Human Readable Part)
isNip19(String str) → bool: Check if a string matches NIP-19 format
isNoteId(String str) → bool: Check if a string is a note ID (note1)
isPrivateKey(String str) → bool: Check if a string is a private key (nsec)
isPubkey(String str) → bool: Check if a string is a public key (npub)
