Node/Pure JavaScript symmetric ciphers adapter
Node/Pure JavaScript symmetric ciphers adapter.
On browsers (or React Native, deno), it’ll use @noble/ciphers
’s implementation for compatibility.
On node (or bun), it’ll use node:crypto
’s implementation for efficiency.
[!NOTE] You may need to polyfill
crypto.getRandomValues
for React Native.There are some limitations, see Known limitations below.
Check the example folder for bun/deno usage.
import { aes256gcm } from "@ecies/ciphers/aes";
import { randomBytes } from "@noble/ciphers/webcrypto";
const TEXT = "hello world🌍!";
const encoder = new TextEncoder();
const decoder = new TextDecoder();
const msg = encoder.encode(TEXT);
const key = randomBytes();
const nonce = randomBytes(16);
const cipher = aes256gcm(key, nonce);
console.log("decrypted:", decoder.decode(cipher.decrypt(cipher.encrypt(msg))));
The API follows @noble/ciphers
’s API for ease of use, you can check their examples as well.
aes-256-gcm
aes-256-cbc
xchacha20-poly1305
or aes-256-gcm
as possible.xchacha20-poly1305
xchacha20-poly1305
is implemented with pure JS hchacha
function and node:crypto
’s chacha20-poly1305
.node:crypto
’s chacha20-poly1305
is not supported on deno and bun, @noble/ciphers
’s implementation is used on both platforms instead.deno
does not support indirect conditional exports. If you use this library to build another library, client code of your library probably falls back to the node:crypto
implementation and may not work properly, specifically aes-256-gcm
(16 bytes nonce) and chacha20-poly1305
.
