Function instantiateSecp256k1Bytes

instantiateSecp256k1Bytes(webassemblyBytes, randomSeed?): Promise<Secp256k1>
This method is like instantiateSecp256k1, but requires the consumer to Window.fetch or fs.readFile the secp256k1.wasm binary and provide it to this method as webassemblyBytes. This skips a base64 decoding of an embedded binary.

Randomizing the Context with randomSeed
This method also accepts an optional, 32-byte randomSeed, which is passed to the contextRandomize method in the underlying WebAssembly.

In the secp256k1 C library, context randomization is an additional layer of security from side-channel attacks that attempt to extract private key information by analyzing things like a CPU's emitted radio frequencies or power usage.

As most applications also benefit from deterministic, reproducible behavior, context is not randomized by default in Libauth. To randomize the context, provide a 32-byte Uint8Array of cryptographically strong random values (e.g. crypto.getRandomValues(new Uint8Array(32))).
Parameters
- webassemblyBytes: ArrayBuffer
  an ArrayBuffer containing the bytes from Libauth's secp256k1.wasm binary. Providing this buffer manually may be faster than the internal base64 decode that happens in instantiateSecp256k1.
- Optional randomSeed: Uint8Array
  a 32-byte random seed used to randomize the secp256k1 context after creation. See above for details.
Returns Promise<Secp256k1>
