ISecp256k1 (DotNetLightning)

ISecp256k1 Type

Namespace: DotNetLightning.Crypto
Assembly: DotNetLightning.Core.dll
Base Type: obj
All Interfaces: ISecp256k1 , IDisposable

An interface responsible for set of low-level cryptographic operation. We need this because there are several types of secp256k1 implementation * 1. NBitcoinSecp256k1 * The one we usually want to use. Which depends on NBitcoin's implementation * 2. BouncySecp256k1 * Fallback when we are compiling with netstandard2.0, since NBitcoin.Secp256k1 does not support older netstandard version. * This will be obsolete when we drop the support for netstandard2.1

Instance members

Instance member	Description
`this.PrivateKeyTweakAdd` Full Usage: `this.PrivateKeyTweakAdd` Parameters: tweak : `ReadOnlySpan<byte>` privateKeyToMutate : `Span<byte>` Returns: `bool` Modifiers: abstract	Add a tweak (32 bytes) to a private key. Causes a mutation to `privateKeyToMutate`. tweak : `ReadOnlySpan<byte>` privateKeyToMutate : `Span<byte>` Returns: `bool`
`this.PrivateKeyTweakMultiply` Full Usage: `this.PrivateKeyTweakMultiply` Parameters: tweak : `ReadOnlySpan<byte>` privKeyToMutate : `Span<byte>` Returns: `bool` Modifiers: abstract	Assume tweak (32 bytes) as a scalar and add `G` (basepoint) for tweak times. Causes a mutation to `privateKeyToMutate` tweak : `ReadOnlySpan<byte>` privKeyToMutate : `Span<byte>` Returns: `bool`
`this.PublicKeyCombine` Full Usage: `this.PublicKeyCombine` Parameters: inputPubKey1 : `Span<byte>` inputPubKey2 : `Span<byte>` Returns: `bool * byte array` Modifiers: abstract	Combine 2 public keys. Input can be either 33 bytes or 64 bytes. So normalization by PublicKeyParse is required. inputPubKey1 : `Span<byte>` inputPubKey2 : `Span<byte>` Returns: `bool * byte array`
`this.PublicKeyCreate` Full Usage: `this.PublicKeyCreate` Parameters: privateKeyInput : `ReadOnlySpan<byte>` Returns: `bool * byte array` Modifiers: abstract	Create uncompressed public key(64 bytes) from private key (32 bytes) privateKeyInput : `ReadOnlySpan<byte>` Returns: `bool * byte array`
`this.PublicKeyParse` Full Usage: `this.PublicKeyParse` Parameters: serializedPublicKey : `ReadOnlySpan<byte>` Returns: `bool * byte array` Modifiers: abstract	Convert compressed pubkey (33 bytes) to secp256k1 compatible style (64 bytes). serializedPublicKey : `ReadOnlySpan<byte>` Returns: `bool * byte array`
`this.PublicKeySerializeCompressed` Full Usage: `this.PublicKeySerializeCompressed` Parameters: publicKey : `ReadOnlySpan<byte>` Returns: `bool * byte array` Modifiers: abstract	Convert secp256k1 compatible style pubkey (64 bytes) into compressed form (33 bytes) publicKey : `ReadOnlySpan<byte>` Returns: `bool * byte array`
`this.PublicKeyTweakMultiply` Full Usage: `this.PublicKeyTweakMultiply` Parameters: tweak : `ReadOnlySpan<byte>` pubKeyToMutate : `Span<byte>` Returns: `bool` Modifiers: abstract	Add a public key (64 bytes) to itself for tweak times. Causes a mutation to `pubKeyToMutate` tweak : `ReadOnlySpan<byte>` pubKeyToMutate : `Span<byte>` Returns: `bool`
