xchacha20

ci

XChaCha20 as defined by the XChaCha20 IRTF CFRG draft.

API

export const KEY_BYTES: number = 32;
export const NONCE_BYTES: number = 24;

export function xchacha20(
  out: Uint8Array,
  key: Uint8Array,
  nonce: Uint8Array,
  counter: number,
  text: Uint8Array
): void;

xchacha20 does not do any input validation. Make sure key and nonce have correct sizes and that counter is an uint32. Also, guarantee that out.byteLength === text.byteLength.
