使用这个包https://github.com/margelo/react-native-quick-crypto，它是基于JSI的，像一个本地解决方案一样工作。

const plaintext =
        '32|RmVZZkFUVmpRRkp0TmJaUm56ZU9qcnJkaXNNWVNpTTU*|iXmckfRWZBGWWELw' +
        'eCBsThSsfUHLeRe0KCsK8ooHgxie0zOINpXxfZi/oNG7uq9JWFVCk70gfzQH8ZUJ' +
        'jAfaFg**';
      const cipher = crypto.createCipheriv('des-ede3-cbc', key, iv);
      let ciph = cipher.update(plaintext, 'utf8', 'hex');
      ciph += cipher.final('hex');

      const decipher = crypto.createDecipheriv('des-ede3-cbc', key, iv);
      let txt = decipher.update(ciph, 'hex', 'utf8');
      txt += decipher.final('utf8');

      assert.strictEqual(
        txt,
        plaintext,
        `encryption/decryption with key ${key} and iv ${iv}`
      );
