示例1: test_encoder
function test_encoder() {
var text = "plain text";
var uint8array = new Uint8Array([]);
// constructor
uint8array = new TextEncoder().encode(text);
uint8array = new TextEncoder("utf-8").encode(text);
uint8array = new TextEncoder("windows-1252", {
NONSTANDARD_allowLegacyEncoding: true
}).encode(text);
uint8array = TextEncoder().encode(text);
uint8array = TextEncoder("utf-8").encode(text);
uint8array = TextEncoder("windows-1252", {
NONSTANDARD_allowLegacyEncoding: true
}).encode(text);
// attributes
var encoder = new TextEncoder();
var encoding: string = encoder.encoding;
// methods
encoder.encode();
encoder.encode(text);
encoder.encode(text, { stream: true });
}示例2: fn
false, ['encrypt','decrypt']).then((dekKey: CryptoKey) => {
let dat: Uint8Array;
if (encrypt) {
// Encode the message string as a byte array
dat = textEncoder.encode(em.message);
// Generate a random IV for seeding AES-CBC
em.iv = new Uint8Array(16);

// Encode the IV to be persisted later
em.ivB64 = b64.fromByteArray(em.iv);
}

// Decode the encrypted message
em.messageEnc = b64.toByteArray(em.messageEncB64);

}
// Setup the encryptiong/decryption parameters
let encryptAlgor = {
name: 'AES-CBC',

// Either encrypt or decrypt
if (encrypt) {
