如何为使用OpenSSL生成的证书提供多行证书名称（CN）-Java 学习之路

我按照这里的步骤Create PKCS#12 file with self-signed certificate via OpenSSL in Windows for my Android App使用OpenSSL生成自签名证书 .

openssl req -x509 -days 365 -subj“/ CN = MULTI LINE NEEDED HERE”-newkey rsa：1024 -keyout mycert.pem -out mycert.pem

这里的主题由cmd的提示填充，如Country，State等 . 我希望为CN属性赋予多行值 . 我如何在命令行中执行此操作？

...当我想要多个域名的情况怎么样？比如www.google.com和www.yahoo.com？

以下是如何向证书添加多个DNS名称 . 您必须通过 Subject Alternate Names （SAN）添加它们 .

在您的情况下，在 alternate_names 部分下添加 www.google.com 和 www.yahoo.com .

（I 'm not sure if this is an answer or a comment. I' m仍然不清楚是否要通过将 CRLF 添加到 Common Name 来尝试破解PKI;或者如果您只想在证书中添加多个DNS名称） .

First

$ touch example-com.conf

Second

将以下内容添加到配置文件中 . 调整它以适合您的口味 .

[ req ]
default_bits        = 2048
default_keyfile     = server-key.pem
distinguished_name  = subject
req_extensions      = extensions
x509_extensions     = extensions
string_mask         = utf8only

[ subject ]
countryName         = Country Name (2 letter code)
countryName_default     = US

stateOrProvinceName     = State or Province Name (full name)
stateOrProvinceName_default = NY

localityName            = Locality Name (eg, city)
localityName_default        = New York

organizationName         = Organization Name (eg, company)
organizationName_default    = Example, LLC

commonName          = Common Name (e.g. server FQDN or YOUR name)
commonName_default      = Example, LLC

emailAddress            = Email Address
emailAddress_default        = test@example.com

[ extensions ]

subjectKeyIdentifier        = hash
authorityKeyIdentifier  = keyid,issuer

basicConstraints        = CA:FALSE
keyUsage            = nonRepudiation, digitalSignature, keyEncipherment
extendedKeyUsage    = serverAuth
subjectAltName          = @alternate_names
nsComment           = "OpenSSL Generated Certificate"

[ alternate_names ]

DNS.1       = example.com
DNS.2       = www.example.com
DNS.3       = mail.example.com
DNS.4       = ftp.example.com

Third

使用以下内容生成证书 . 它会为每个请求生成一个新密钥 . 调整它以适合您的口味 . 例如，如果省略 -x509 ，则会获得CSR而不是证书 .

$ openssl req -config example-com.conf -new -x509 -newkey rsa:2048 -nodes \
        -keyout example-com.key.pem -days 365 -out example-com.cert.pem

Fourth

使用以下内容检查证书 .

$ openssl x509 -in example-com.cert.pem -text -noout

您将在SAN中看到多个DNS名称 .

$ openssl x509 -in example-com.cert.pem -text -noout
