+##### `getPublicKey(privateKey)`
+```typescript
+function getPublicKey(privateKey: Uint8Array, isCompressed?: false): Uint8Array;
+function getPublicKey(privateKey: string, isCompressed?: false): string;
+function getPublicKey(privateKey: bigint): Uint8Array;
+```
+`privateKey` will be used to generate public key.
+  Public key is generated by doing scalar multiplication of a base Point(x, y) by a fixed
+  integer. The result is another `Point(x, y)` which we will by default encode to hex Uint8Array.
+`isCompressed` (default is `false`) determines whether the output should contain `y` coordinate of the point.
+
+To get Point instance, use `Point.fromPrivateKey(privateKey)`.
+
+##### `getSharedSecret(privateKeyA, publicKeyB)`
+```typescript
+function getSharedSecret(privateKeyA: Uint8Array, publicKeyB: Uint8Array): Uint8Array;
+function getSharedSecret(privateKeyA: string, publicKeyB: string): string;
+function getSharedSecret(privateKeyA: bigint, publicKeyB: Point): Uint8Array;
+```
+
+Computes ECDH (Elliptic Curve Diffie-Hellman) shared secret between a private key and a different public key.
+
+To get Point instance, use `Point.fromHex(publicKeyB).multiply(privateKeyA)`.
+
+To speed-up the function massively by precomputing EC multiplications,
+use `getSharedSecret(privateKeyA, secp.utils.precompute(8, publicKeyB))`
+
+
+##### `sign(hash, privateKey)`
+```typescript
+function sign(msgHash: Uint8Array, privateKey: Uint8Array, opts?: Options): Promise<Uint8Array>;
+function sign(msgHash: string, privateKey: string, opts?: Options): Promise<string>;
+function sign(msgHash: Uint8Array, privateKey: Uint8Array, opts?: Options): Promise<[Uint8Array | string, number]>;
+```
+
+Generates deterministic ECDSA signature as per RFC6979.
+
+- `msgHash: Uint8Array | string` - message hash which would be signed
+- `privateKey: Uint8Array | string | bigint` - private key which will sign the hash
+- `options?: Options` - *optional* object related to signature value and format
+- `options?.recovered: boolean = false` - whether the recovered bit should be included in the result. In this case, the result would be an array of two items.
+- `options?.canonical: boolean = false` - whether a signature `s` should be no more than 1/2 prime order
+- `options?.der: boolean = true` - whether the returned signature should be in DER format. If `false`, it would be in Compact format (32-byte r + 32-byte s)
+
+The function is asynchronous because we're utilizing built-in HMAC API to not rely on dependencies.
+
+`signSync` counterpart could also be used, you need to set `utils.hmacSha256Sync` to a function with signature `key: Uint8Array, ...messages: Uint8Array[]) => Uint8Array`. Example with `noble-hashes` package:
+
+```ts
+const { hmac } = require('noble-hashes/lib/hmac');
+const { sha256 } = require('noble-hashes/lib/sha256');
+secp256k1.utils.hmacSha256Sync = (key: Uint8Array, ...msgs: Uint8Array[]) => {
+  const h = hmac.create(sha256, key);
+  msgs.forEach(msg => h.update(msg));
+  return h.digest();
+};
+
+// Can be used now
+secp256k1.signSync(msgHash, privateKey)
+```
+
+##### `verify(signature, hash, publicKey)`
+```typescript
+function verify(signature: Uint8Array, msgHash: Uint8Array, publicKey: Uint8Array): boolean
+function verify(signature: string, msgHash: string, publicKey: string): boolean
+```
+- `signature: Uint8Array | string | { r: bigint, s: bigint }` - object returned by the `sign` function
+- `msgHash: Uint8Array | string` - message hash that needs to be verified
+- `publicKey: Uint8Array | string | Point` - e.g. that was generated from `privateKey` by `getPublicKey`
+- Returns `boolean`: `true` if `signature == hash`; otherwise `false`
+
+##### `recoverPublicKey(hash, signature, recovery)`
+```typescript
+function recoverPublicKey(msgHash: Uint8Array, signature: Uint8Array, recovery: number): Uint8Array | undefined;
+function recoverPublicKey(msgHash: string, signature: string, recovery: number): string | undefined;
+```
+- `msgHash: Uint8Array | string` - message hash which would be signed
+- `signature: Uint8Array | string | { r: bigint, s: bigint }` - object returned by the `sign` function
+- `recovery: number` - recovery bit returned by `sign` with `recovered` option
+  Public key is generated by doing scalar multiplication of a base Point(x, y) by a fixed
+  integer. The result is another `Point(x, y)` which we will by default encode to hex Uint8Array.
+  If signature is invalid - function will return `undefined` as result.
+
+To get Point instance, use `Point.fromSignature(hash, signature, recovery)`.
+
+##### `schnorr.getPublicKey(privateKey)`
+```typescript
+function schnorrGetPublicKey(privateKey: Uint8Array): Uint8Array;
+function schnorrGetPublicKey(privateKey: string): string;
+```
+
+Returns 32-byte public key. *Warning:* it is incompatible with non-schnorr pubkey.
+
+Specifically, its *y* coordinate may be flipped. See BIP0340 for clarification.
+
+##### `schnorr.sign(hash, privateKey)`
+```typescript
+function schnorrSign(msgHash: Uint8Array, privateKey: Uint8Array, auxilaryRandom?: Uint8Array): Promise<Uint8Array>;
+function schnorrSign(msgHash: string, privateKey: string, auxilaryRandom?: string): Promise<string>;
+```
+
+Generates Schnorr signature as per BIP0340. Asynchronous, so use `await`.
+
+- `msgHash: Uint8Array | string` - message hash which would be signed
+- `privateKey: Uint8Array | string | bigint` - private key which will sign the hash
+- `auxilaryRandom?: Uint8Array` — optional 32 random bytes. By default, the method gathers cryptogarphically secure random.
+- Returns Schnorr signature in Hex format.
+
+##### `schnorr.verify(signature, hash, publicKey)`
+```typescript
+function schnorrVerify(signature: Uint8Array | string, msgHash: Uint8Array | string, publicKey: Uint8Array | string): boolean
+```
+- `signature: Uint8Array | string | { r: bigint, s: bigint }` - object returned by the `sign` function
+- `msgHash: Uint8Array | string` - message hash that needs to be verified
+- `publicKey: Uint8Array | string | Point` - e.g. that was generated from `privateKey` by `getPublicKey`
+- Returns `boolean`: `true` if `signature == hash`; otherwise `false`
+
+#### Point methods
+
+##### Helpers
+
+###### `utils.randomPrivateKey(): Uint8Array`
+
+Returns `Uint8Array` of 32 cryptographically secure random bytes that can be used as private key. The signature is:
+
+```ts
+(key: Uint8Array, ...msgs: Uint8Array[]): Uint8Array;
+```
+
+###### `utils.hmacSha256Sync`
+
+The function is not defined by default, but could be used to implement `signSync` method (see above).
+
+###### `utils.precompute(W = 8, point = BASE_POINT): Point`
+
+Returns cached point which you can use to pass to `getSharedSecret` or to `#multiply` by it.
+
+This is done by default, no need to run it unless you want to
+disable precomputation or change window size.
+
+We're doing scalar multiplication (used in getPublicKey etc) with
+precomputed BASE_POINT values.
+
+This slows down first getPublicKey() by milliseconds (see Speed section),
+but allows to speed-up subsequent getPublicKey() calls up to 20x.
+
+You may want to precompute values for your own point.
+
+```typescript
+secp256k1.CURVE.P // Field, 2 ** 256 - 2 ** 32 - 977
+secp256k1.CURVE.n // Order, 2 ** 256 - 432420386565659656852420866394968145599
+secp256k1.Point.BASE // new secp256k1.Point(Gx, Gy) where
+// Gx = 55066263022277343669578718895168534326250603453777594175500187360389116729240n

+
+// Elliptic curve point in Affine (x, y) coordinates.
+secp256k1.Point {
+  constructor(x: bigint, y: bigint);
+  // Supports compressed and non-compressed hex
+  static fromHex(hex: Uint8Array | string);
+  static fromPrivateKey(privateKey: Uint8Array | string | number | bigint);
+  static fromSignature(
+    msgHash: Hex,
+    signature: Signature,
+    recovery: number | bigint
+  ): Point | undefined {
+  toRawBytes(isCompressed = false): Uint8Array;
+  toHex(isCompressed = false): string;
+  equals(other: Point): boolean;
+  negate(): Point;
+  add(other: Point): Point;
+  subtract(other: Point): Point;
+  // Constant-time scalar multiplication.
+  multiply(scalar: bigint | Uint8Array): Point;
+}
+secp256k1.Signature {
+  constructor(r: bigint, s: bigint);
+  // DER encoded ECDSA signature
+  static fromDER(hex: Uint8Array | string);
+  // R, S 32-byte each
+  static fromCompact(hex: Uint8Array | string);

+## Security
+
+Noble is production-ready.
+
+1. The library has been audited by an independent security firm cure53: [PDF](https://cure53.de/pentest-report_noble-lib.pdf). The audit has been [crowdfunded](https://gitcoin.co/grants/2451/audit-of-noble-secp256k1-cryptographic-library) by community with help of [Umbra.cash](https://umbra.cash).
+2. The library has also been fuzzed by [Guido Vranken's cryptofuzz](https://github.com/guidovranken/cryptofuzz). You can run the fuzzer by yourself to check it.
+
+We're using built-in JS `BigInt`, which is "unsuitable for use in cryptography" as [per official spec](https://github.com/tc39/proposal-bigint#cryptography). This means that the lib is potentially vulnerable to [timing attacks](https://en.wikipedia.org/wiki/Timing_attack). But, *JIT-compiler* and *Garbage Collector* make "constant time" extremely hard to achieve in a scripting language. Which means *any other JS library doesn't use constant-time bigints*. Including bn.js or anything else. Even statically typed Rust, a language without GC, [makes it harder to achieve constant-time](https://www.chosenplaintext.ca/open-source/rust-timing-shield/security) for some cases. If your goal is absolute security, don't use any JS lib — including bindings to native ones. Use low-level libraries & languages. Nonetheless we've hardened implementation of koblitz curve multiplication to be algorithmically constant time.
+
+We however consider infrastructure attacks like rogue NPM modules very important; that's why it's crucial to minimize the amount of 3rd-party dependencies & native bindings. If your app uses 500 dependencies, any dep could get hacked and you'll be downloading rootkits with every `npm install`. Our goal is to minimize this attack vector.
