问题 When generate a CSR using OpenSSL you have two options: 1) Generate a Private key when the CSR is generated 2) Use the private key to derive a public key and use the public key to create the CSR Does the CSR need to be signed with the matching private key for the CA to validate it? Hypothetically, what if i have TWO key pairs (PubKey1, PrivKey1, PubKey2, PrivKey2). First thing i do is move PrivKey1 to another place. Is there a way where I can use PubKey1 to make the CSR (Without access to

如何申请邮件安全证书（S/MIME）实现邮件加密和数字签名

邮件作为目前互联网最为开放的沟通工具，在大家的工作和生活中，使用的频率非常高。特别是商务办公领域，邮件交流会涉及到很多的商业机密以及交易流程。正因为如此，邮件也会经常受到***或者不法分子的***。 那么如何才能确保邮件的安全可靠呢？ 我们可以通过S/MIME协议来解决这个问题，S/MIME协议支持邮件的认证、完整性保护、鉴定及数据保密等，也就是大家经常听到的用邮件安全证书（S/MIME）来实现邮件的加密和数字签名（加密的作用是为了对邮件的内容进行加密，数字签名的作用是为了确保邮件内容未被篡改，保证邮件内容的完整性）。 目前支持S/MIME协议的邮件客户端，国内只有密信邮件客户端，国外有Outlook、雷鸟、Imail等。 邮件安全证书也和SSL证书一样，分为可信和不可信两种。可信的邮件证书outlook中显示的状态分别如下： 可信的邮件安全证书都是付费的，目前国内能够申请购买可信邮件安全证书的厂商也不少，但从价格和申请便捷性方面来看，目前密信提供的可信邮件安全证书是性价比最高的，价格为98元/年，平均一天只要0.26元。 今天我就来教大家该如何在密信申请全球信任邮件安全证书，希望能够帮助到大家。 （1）打开密信官网（www.mesign.com）,点击瞅一眼栏目下面的全球信任的邮件证书购买链接； （2）填写好邮箱信息，选择购买数量和年限； （3）完成支付； （4）支付完成后

在CentOS和RHEL中配置SNMPv3

由 早过忘川 提交于 2021-02-05 03:06:22
首先，使用yum安装必要的软件 [root@server ~]# yum install net-snmp-utils net-snmp-devel 安装完成之后， 先停止snmpd，再创建具有只读属性的SNMP 账户。 . [root@server ~]# service snmpd stop [root@server ~]# net-snmp-create-v3-user -A snmpv3pass -a MD5 -x DES snmpv3user ================================================================== snmp V3的方式设置简单，而且安全性更高。 配置方法： 1.停止snmpd服务 #service snmpd stop 2.增加snmpv3用户，并设置认证以及加密方式 # net-snmp-create-v3-user Enter a SNMPv3 user name to create: enocsnmpv3 Enter authentication pass-phrase: enocsnmpv3pw Enter encryption pass-phrase: [press return to reuse the authentication pass-phrase] enocsnmpv3pk

Is it possible to set subjectAltName using pyOpenSSL?

由 半城伤御伤魂 提交于 2021-02-04 18:50:30
问题 I need to generate SSL certificates from Python using pyOpenSSL. Does anyone know if it's possible to set subjectAltName? From the documentation (https://pythonhosted.org/pyOpenSSL/api/crypto.html#x509-objects) it doesn't seem so. In fact, only a set_subject method is provided. Is there any way to add that to the certificate? 回答1: san_list = ["DNS:*.google.com", "DNS:google.ym"] cert.add_extensions([ OpenSSL.crypto.X509Extension( "subjectAltName", False, ", ".join(san_list) ) ]) 回答2: I
