const {createICSAFile, createEICSAFile, writeICSAFile, writeEICSAFile, writeICSADir, readICSAFile, readEICSAFile} = require("icsa");

// Create File
let file = await createICSAFile("path/to/dir"); // => <Buffer ...> // Use await createEICSAFile("path/to/file.icsa", "32 key length") for create encrypted icsa;

// Write File
let write = await writeICSAFile("path/to/dir"[, "path/to/file.icsa"]); // => 'file "path/to/file.icsa" created' // Use await writeEICSAFile("path/to/file.icsa", "32 key length"[, "path/to/file.icsa"]) for write encrypted icsa;

// Read File
let icsa = await readICSAFile("path/to/file.icsa"); // Use await readEICSAFile("path/to/file.icsa", "32 key length") for read encrypted icsa

//Write Dir
let dir = await writeICSADir(/* ICSA class (see readICSAFile) */, "path/to/dir"); // => 'dir "path/to/dir" created'
