ECPrivateKey class
Represents an ECC private key for use with the secp256k1 curve
Constructors
- ECPrivateKey.new(Uint8List data, {bool compressed = true})
-
Constructs a private key from a 32-byte scalar. The public key may be
in the
compressedformat which is the default. InvalidPrivateKey will be thrown if the private key is not within the secp256k1 order. - ECPrivateKey.fromHex(String hex, {bool compressed = true})
-
Constructs a private key from HEX encoded data. The public key may be in
the
compressedformat which is the default. - ECPrivateKey.generate({bool compressed = true})
- Generates a private key using a CSPRING.
Properties
- compressed → bool
-
True if the derived public key should be in compressed format
final
- data → Uint8List
-
no setter
- hashCode → int
-
The hash code for this object.

- pubkey → ECPublicKey
-
The public key associated with this private key
no setter
- runtimeType → Type
-
A representation of the runtime type of the object.

- xonly → ECPrivateKey
-
Get the private key where the public key always has an even Y-coordinate
for any X-coordinate. This is used for Schnorr signatures.

Methods
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.

-
toString(
) → String -
A string representation of this object.

-
tweak(
Uint8List scalar) → ECPrivateKey? - Tweaks the private key with a scalar. In the instance a new key cannot be created (practically impossible for random 32-bit scalars), then null will be returned.
Operators
-
operator ==(
Object other) → bool -
The equality operator.
