aes加密 返回的值转换数组问题

最终encrypted返回的是 类似 [45 128 2 198 139 6 120 149 1 4 235 109 213] 值 请问我如何将他转换为数组呢

func (this *AesEncrypt) Encrypt(strMesg string) ([]byte, error) {
    key := this.getKey()
    var iv = []byte(key)[:aes.BlockSize]
    encrypted := make([]byte, len(strMesg))
    aesBlockEncrypter, err := aes.NewCipher(key)
    if err != nil {
        return nil, err
    }
    aesEncrypter := cipher.NewCFBEncrypter(aesBlockEncrypter, iv)
    aesEncrypter.XORKeyStream(encrypted, []byte(strMesg))
    return encrypted, nil
}
