目前是支持引入外部公钥进行加密的，具体可以参照以下demo
async genRsaPubKey () {
const pubKey = "asdasd123231dsasdasd123123asdasd12312xxxxxxxxxxxxxxxxxxxxxxxxxxxx";
/*
* 引入外部的公钥加密
* */
const base64 = new util.Base64Helper()
let publicKeyDataBlob: cryptoFramework.DataBlob = { data: base64.decodeSync(pubKey) };
let asyKeyGenerator = cryptoFramework.createAsyKeyGenerator('RSA1024');
let cipher = cryptoFramework.createCipher('RSA|ECB|PKCS1'); //创建一个 Cipher (解密)对象
let keyGenPromise: cryptoFramework.KeyPair = await asyKeyGenerator.convertKey(publicKeyDataBlob, null);
await cipher.init(cryptoFramework.CryptoMode.ENCRYPT_MODE, keyGenPromise.pubKey, null);
const plaintext = '我是明文'
let put: cryptoFramework.DataBlob = { data: new Uint8Array(buffer.from(plaintext).buffer) };
const finalRes = await cipher.doFinal(put)
console.log(TAG, `加密成功 ${finalRes.data}`)

在HarmonyOS鸿蒙Next中，ArkTS实现RSA加密可以通过@ohos.security.cryptoFramework模块来完成。首先，需要导入该模块：
import cryptoFramework from '@ohos.security.cryptoFramework';接下来，创建一个Cipher实例，指定使用RSA算法：
let cipher = cryptoFramework.createCipher("RSA1024|PKCS1");然后，生成RSA密钥对。可以使用KeyPairGenerator来生成公钥和私钥：
let keyPairGenerator = cryptoFramework.createKeyPairGenerator("RSA1024");
keyPairGenerator.generateKeyPair((err, keyPair) => {
if (err) {
console.error("Key pair generation failed: " + err.message);
return;
}
let pubKey = keyPair.pubKey;
let priKey = keyPair.priKey;
});使用公钥进行加密：
cipher.init(cryptoFramework.CryptoMode.ENCRYPT_MODE, pubKey, null)
.then(() => {
let plainText = "This is the plain text.";
let input = { data: stringToUint8Array(plainText) };
return cipher.doFinal(input);
})
.then((output) => {
console.info("Encrypted data: " + uint8ArrayToString(output.data));
})
.catch((err) => {
console.error("Encryption failed: " + err.message);
});使用私钥进行解密：
cipher.init(cryptoFramework.CryptoMode.DECRYPT_MODE, priKey, null)
.then(() => {
let encryptedData = "Encrypted data here";
let input = { data: stringToUint8Array(encryptedData) };
return cipher.doFinal(input);
})
.then((output) => {
console.info("Decrypted data: " + uint8ArrayToString(output.data));
})
.catch((err) => {
console.error("Decryption failed: " + err.message);
});以上代码展示了如何在ArkTS中使用RSA进行加密和解密操作。
