HarmonyOS 的MD5加密可以参考下面demo：

import cryptoFramework from '@ohos.security.cryptoFramework';
import buffer from '@ohos.buffer';

@Entry
@Component
struct Page6251 {
  @State message: string = 'Hello World';

  build() {
    Button('MD5加密').width(100).height(100).onClick(async () => {
      let md = cryptoFramework.createMd('MD5');
      await md.update({ data: new Uint8Array(buffer.from('中国您好', 'utf-8').buffer) });
      let mdOutput = await md.digest();
      console.info('[Promise]: MD result1: ' + mdOutput.data);
      const result = Array.from(mdOutput.data).map(byte => byte.toString(16)).join('')
      console.info("ssss:", result)
    })
  }
}
