说完(wan)量子密(mi)钥(yao)加(jia)密(mi)咱们再来(lai)说说无痕阅(yue)览(lan)(lan)吧。当我们有(you)重(zhong)要(yao)的(de)(de)(de)信(xin)息或(huo)重(zhong)要(yao)文件(jian)(jian)(jian)(jian)需(xu)(xu)要(yao)告(gao)知对(dui)方(fang)并且(qie)需(xu)(xu)要(yao)对(dui)方(fang)保密(mi)时(shi)，可以选择(ze)通(tong)(tong)过(guo)(guo)我们司空的(de)(de)(de)加(jia)密(mi)邮(you)(you)件(jian)(jian)(jian)(jian)的(de)(de)(de)形(xing)(xing)(xing)式发(fa)(fa)送无痕阅(yue)览(lan)(lan)的(de)(de)(de)信(xin)息或(huo)邮(you)(you)件(jian)(jian)(jian)(jian)，目(mu)前版本通(tong)(tong)过(guo)(guo)聊天形(xing)(xing)(xing)式或(huo)邮(you)(you)件(jian)(jian)(jian)(jian)形(xing)(xing)(xing)式发(fa)(fa)送的(de)(de)(de)无痕阅(yue)览(lan)(lan)信(xin)息或(huo)邮(you)(you)件(jian)(jian)(jian)(jian)已实现了防复制以及防转发(fa)(fa)的(de)(de)(de)功能(neng)(neng)，并且(qie)在阅(yue)读返回后信(xin)息和邮(you)(you)件(jian)(jian)(jian)(jian)将自动焚毁，以防对(dui)方(fang)通(tong)(tong)过(guo)(guo)截图模式泄漏重(zhong)要(yao)文件(jian)(jian)(jian)(jian)以及重(zhong)要(yao)信(xin)息。同时(shi)，通(tong)(tong)过(guo)(guo)聊天形(xing)(xing)(xing)式和邮(you)(you)件(jian)(jian)(jian)(jian)形(xing)(xing)(xing)式发(fa)(fa)送的(de)(de)(de)无痕阅(yue)览(lan)(lan)信(xin)息及邮(you)(you)件(jian)(jian)(jian)(jian)，同样不可转发(fa)(fa)。来(lai)测试一(yi)下司空的(de)(de)(de)加(jia)密(mi)邮(you)(you)件(jian)(jian)(jian)(jian)是(shi)否能(neng)(neng)查看吧？一(yi)次一(yi)密(mi)的(de)(de)(de)邮(you)(you)件(jian)(jian)(jian)(jian)加(jia)密(mi)安全吗

《中(zhong)华(hua)人(ren)民共和国数据(ju)安全法》于2021年(nian)6月10日通过，自2021年(nian)9月1日开始(shi)施行。其中(zhong)“数据(ju)”二(er)字(zi)(zi)，指的(de)(de)(de)是(shi)任何电子或其他(ta)方式对(dui)信(xin)息的(de)(de)(de)记录(lu)。国家(jia)保护个人(ren)、组织与数据(ju)有(you)关的(de)(de)(de)权益，鼓励(li)数据(ju)依(yi)(yi)法合(he)理有(you)效地利用(yong)，保障数据(ju)依(yi)(yi)法有(you)序自由流动，促进以数据(ju)为(wei)关键要素(su)的(de)(de)(de)数字(zi)(zi)经(jing)济发展。司(si)空(kong)应用(yong)软件作为(wei)一款加(jia)密(mi)工具，设计初(chu)衷就是(shi)为(wei)了保护个人(ren)的(de)(de)(de)隐私及(ji)数据(ju)在第三(san)方服务器的(de)(de)(de)安全，充分响应了号(hao)召(zhao)，为(wei)个人(ren)或企业(ye)数据(ju)安全保驾护航，贡(gong)献一份力量。怎样给邮(you)件加(jia)密(mi)工具司(si)空(kong)邮(you)件加(jia)密(mi)方式采用(yong)SM4分组密(mi)码算法。

收发(fa)加密邮(you)件的前提是(shi)(shi)双方(fang)都是(shi)(shi)司空(kong)用户(hu)，如互为好(hao)(hao)友(you)(you)，那(nei)么(me)发(fa)邮(you)件就会比较方(fang)便，只(zhi)需在通(tong)讯(xun)录选择(ze)收件人即可，不需要繁琐地输(shu)入(ru)邮(you)件地址了(le)。那(nei)我们来看(kan)看(kan)怎(zen)么(me)添加好(hao)(hao)友(you)(you)吧！在应用中找到右(you)上(shang)角⊕按钮，有(you)两种(zhong)添加好(hao)(hao)友(you)(you)方(fang)式，扫(sao)对(dui)方(fang)司空(kong)二(er)维码或直(zhi)接(jie)输(shu)入(ru)对(dui)方(fang)的手(shou)机(ji)(ji)号。对(dui)方(fang)手(shou)机(ji)(ji)号未注册司空(kong)，不能(neng)添加，搜索注册过司空(kong)的手(shou)机(ji)(ji)号可发(fa)送(song)好(hao)(hao)友(you)(you)申(shen)(shen)请(qing)。你可在好(hao)(hao)友(you)(you)申(shen)(shen)请(qing)页面备注好(hao)(hao)友(you)(you)名称(cheng)，也可给对(dui)方(fang)发(fa)送(song)留言。对(dui)方(fang)通(tong)过后则添加成功(gong)，双方(fang)如都绑定了(le)邮(you)箱，就可以体验(yan)聊(liao)天和(he)邮(you)件模块了(le)。

司空的聊天实际是邮(you)件(jian)加(jia)密(mi)(mi)(mi)(mi)(mi)(mi)功能的另一(yi)种展现形式，现阶段支持文(wen)字信息、图(tu)片、视(shi)频、音频、常用(yong)(yong)(yong)文(wen)档的发(fa)送，和(he)我们平常使用(yong)(yong)(yong)的微信没(mei)有太大区别，非常符合(he)用(yong)(yong)(yong)户现有的使用(yong)(yong)(yong)习惯(guan)。基于电子邮(you)箱的聊天模(mo)式，使用(yong)(yong)(yong)收(shou)发(fa)自如，用(yong)(yong)(yong)户得(de)心应手。“量(liang)子密(mi)(mi)(mi)(mi)(mi)(mi)钥(yao)加(jia)密(mi)(mi)(mi)(mi)(mi)(mi)”开关(guan)默认开启模(mo)式，所以(yi)加(jia)密(mi)(mi)(mi)(mi)(mi)(mi)过程无需特别操(cao)作，收(shou)信方jie密(mi)(mi)(mi)(mi)(mi)(mi)密(mi)(mi)(mi)(mi)(mi)(mi)钥(yao)在收(shou)取(qu)消息的同(tong)时(shi)同(tong)步收(shou)取(qu)，打开阅览，文(wen)件(jian)实时(shi)jie密(mi)(mi)(mi)(mi)(mi)(mi)。用(yong)(yong)(yong)户加(jia)/操(cao)作无感，交流轻(qing)松便捷。虽然司空是一(yi)款加(jia)密(mi)(mi)(mi)(mi)(mi)(mi)工具，但其中的加(jia)密(mi)(mi)(mi)(mi)(mi)(mi)聊天更(geng)贴(tie)近生活，在意个人(ren)隐私的用(yong)(yong)(yong)户，完全(quan)可以(yi)尝试体验(yan)一(yi)下。邮(you)件(jian)加(jia)密(mi)(mi)(mi)(mi)(mi)(mi)可以(yi)提高企业的竞争力，让(rang)客户选择更(geng)安全(quan)的企业进(jin)行业务合(he)作。
