_section: React Native @<cookbook-react-native>

|
When using React Native, many of the built-in cryptographic primitives
|
||
|
|
can be replaced by native, substantially faster implementations.
|
||
|
|
|
||
|
|
This should be available in its own package in the future, but for now
|
||
|
|
this is highly recommended, and requires installing the
|
||
|
|
[[link-npm-react-native-quick-crypto]] package.
|
||
|
|
|
||
|
|
|
||
|
|
_code:
|
||
|
|
|
||
|
|
import { ethers } from "ethers";
|
||
|
|
|
||
|
|
import crypto from "react-native-quick-crypto";
|
||
|
|
|
||
|
|
ethers.randomBytes.register((length) => {
|
||
|
|
return new Uint8Array(crypto.randomBytes(length));
|
||
|
|
});
|
||
|
|
|
||
|
|
ethers.computeHmac.register((algo, key, data) => {
|
||
|
|
return crypto.createHmac(algo, key).update(data).digest();
|
||
|
|
});
|
||
|
|
|
||
|
|
ethers.pbkdf2.register((passwd, salt, iter, keylen, algo) => {
|
||
|
|
return crypto.pbkdf2Sync(passwd, salt, iter, keylen, algo);
|
||
|
|
});
|
||
|
|
|
||
|
|
ethers.sha256.register((data) => {
|
||
|
|
return crypto.createHash('sha256').update(data).digest();
|
||
|
|
});
|
||
|
|
|
||
|
|
ethers.sha512.register((data) => {
|
||
|
|
return crypto.createHash('sha512').update(data).digest();
|

});
