Function createInstructionSetBCH

Parameters

• standard: boolean = true

  If true, the additional isStandard validations will be enabled. Transactions that fail these rules are often called "non-standard" and can technically be included by miners in valid blocks, but most network nodes will refuse to relay them. (Default: true)

  • ripemd160: {
        hash: ((input: Uint8Array) => Uint8Array);
    }

    a Ripemd160 implementation

    • hash: ((input: Uint8Array) => Uint8Array)

      • • (input: Uint8Array): Uint8Array

        • Returns the ripemd160 hash of the provided input.

          To incrementally construct a ripemd160 hash (e.g. for streaming), use init, update, and final.

          Parameters

          • input: Uint8Array

            a Uint8Array to be hashed using ripemd160

          Returns Uint8Array

  • secp256k1: {
        verifySignatureDERLowS: ((signature: Uint8Array, publicKey: Uint8Array, messageHash: Uint8Array) => boolean);
        verifySignatureSchnorr: ((signature: Uint8Array, publicKey: Uint8Array, messageHash: Uint8Array) => boolean);
    }

    a Secp256k1 implementation

    • verifySignatureDERLowS: ((signature: Uint8Array, publicKey: Uint8Array, messageHash: Uint8Array) => boolean)

      • • (signature: Uint8Array, publicKey: Uint8Array, messageHash: Uint8Array): boolean

        • Verify a DER-encoded ECDSA signature using the provided publicKey and messageHash. This method also returns false if the signature is not in normalized lower-S form.

          Parameters

          • signature: Uint8Array

            a DER-encoded ECDSA signature to verify, max 72 bytes

          • publicKey: Uint8Array

            a public key, in either compressed (33-byte) or uncompressed (65-byte) format

          • messageHash: Uint8Array

            the 32-byte message hash signed by the signature

          Returns boolean

    • verifySignatureSchnorr: ((signature: Uint8Array, publicKey: Uint8Array, messageHash: Uint8Array) => boolean)

      • • (signature: Uint8Array, publicKey: Uint8Array, messageHash: Uint8Array): boolean

        • Verify a Secp256k1 EC-Schnorr-SHA256 signature (Bitcoin Cash construction).

          Parameters

          • signature: Uint8Array

            a 64-byte schnorr signature to verify

          • publicKey: Uint8Array

            a public key, in either compressed (33-byte) or uncompressed (65-byte) format

          • messageHash: Uint8Array

            the 32-byte message hash signed by the signature

          Returns boolean

  • sha1: {
        hash: ((input: Uint8Array) => Uint8Array);
    }

    a Sha1 implementation

    • hash: ((input: Uint8Array) => Uint8Array)

      • • (input: Uint8Array): Uint8Array

        • Returns the sha1 hash of the provided input.

          To incrementally construct a sha1 hash (e.g. for streaming), use init, update, and final.

          Parameters

          • input: Uint8Array

            a Uint8Array to be hashed using sha1

          Returns Uint8Array

  • sha256: {
        hash: ((input: Uint8Array) => Uint8Array);
    }

    a Sha256 implementation

    • hash: ((input: Uint8Array) => Uint8Array)

      • • (input: Uint8Array): Uint8Array

        • Returns the sha256 hash of the provided input.

          To incrementally construct a sha256 hash (e.g. for streaming), use init, update, and final.

          Parameters

          • input: Uint8Array

            a Uint8Array to be hashed using sha256

          Returns Uint8Array
