Methods

countDifficultyOfHex(String hexString) → int

Counts the difficulty of the given hexString, this wis intebded t be used in the NIP 13 with this package.

override

decodeBech32(String bech32String) → List<String>

Decodes a bech32 string into a hex string and a hrp human readable part.

override

decodeNeventToMap(String bech32) → Map<String, dynamic>

Decodes the given bech32 nprofile id to a map with pubkey and relays. You can encode a map to a nprofile id with encodeNProfile.

override

decodeNprofileToMap(String bech32) → Map<String, dynamic>

Decodes the given bech32 nprofile id to a map with pubkey and relays. You can encode a map to a nprofile id with encodeNProfile.

override

encodeBech32(String hex, String hrp) → String

Encodes a hex string into a bech32 string with a hrp human readable part.

override

encodeNevent({required String eventId, required String pubkey, List<String> userRelays = const []}) → String

Generates a nprofile id from the given eventId, pubkey and relays. You can decode the generated nprofile id with decodeNeventToMap.

override

encodeNProfile({required String pubkey, List<String> userRelays = const []}) → String

Generates a nprofile id from the given pubkey and relays, if no relays are given, it will be an empty list. You can decode the generated nprofile id with decodeNprofileToMap.

override

hexEncodeString(String input) → String

Encodes the given input to hex format

override

isValidNip05Identifier(String identifier) → bool

Wether the given identifier has a valid format.

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

pubKeyFromIdentifierNip05({required String internetIdentifier}) → Future<String>

Return the public key found by the NIP05 implementation via the given for the given internetIdentifier

override

random64HexChars() → String

Generates a randwom 64-length hexadecimal string.

override

toString() → String

A string representation of this object.

inherited

verifyNip05({required String internetIdentifier, required String pubKey}) → Future<bool>

This method will verify the internetIdentifier with a pubKey using the NIP05 implementation, and simply will return a Future with a bool that indicates if the verification was successful or not.

override

Operators

operator ==(Object other) → bool

The equality operator.
