identity/identity library

Classes

DelegationChain
A chain of delegations. This is JSON Serializable. This is the object to serialize and pass to a DelegationIdentity. It does not keep any private keys.
DelegationIdentity
An Identity that adds delegation to a request. Everywhere in this class, the name innerKey refers to the SignIdentity that is being used to sign the requests, while originalKey is the identity that is being borrowed. More identities can be used in the middle to delegate.

Constants

hardened → const int
The following part is ported from InternetIdentity service. It's main purpose is to recover an identity that registered. These truths are covered.
icBasePath → const List<int>
icDerivationPath → const List<int>

Functions

bufEquals(ByteBuffer b1, ByteBuffer b2) → bool
bytesUnwrapDer(Uint8List derEncoded, Uint8List oid) → Uint8List
Extracts a payload from the given derEncoded data, and checks that it was tagged with the given oid.
bytesUnwrapDerSignature(Uint8List derEncoded) → Uint8List
ECDSA DER Signature 0x30|b1|0x02|b2|r|0x02|b3|s b1 = Length of remaining data b2 = Length of r b3 = Length of s
bytesWrapDer(Uint8List payload, Uint8List oid) → Uint8List
Wraps the given payload in a DER encoding tagged with the given encoded oid like so: SEQUENCE(oid, BITSTRING(payload))
bytesWrapDerSignature(Uint8List rawSignature) → Uint8List
decodeLenBytes(Uint8List buf, int offset) → int
derive(Uint8List parentKey, Uint8List parentChaincode, int i) → Set<Uint8List>
dropLeadingUserNumber(String s) → String
encodeLen(Uint8List buf, int offset, int len) → int
encodeLenBytes(int len) → int
extractUserNumber(String s) → BigInt?
fromMnemonicWithoutValidation(String mnemonic, List<int>? derivationPath, {int offset = hardened}) → Future<Ed25519KeyIdentity>
