生成 RSA 密钥:
openssl genrsa -out example.key [bits]
打印 RSA 密钥的文本表示:
openssl rsa -in example.key -text -noout
生成新的 RSA 密钥并使用基于 AES CBC 256 加密的密码短语进行加密:
openssl genrsa -aes256 -out example.key [bits]
检查您的私钥。如果密钥有密码短语,系统会提示您输入密码:
openssl rsa -check -in example.key
从密钥中删除密码:
openssl rsa -in example.key -out example.key
使用密码短语加密现有私钥:
openssl rsa -des3 -in example.key -out example_with_pass.key
生成 ECDSA 密钥。curve 将替换为:prime256v1、secp384r1、secp521r1 或任何其他支持的
openssl ecparam -genkey -name [curve] | openssl ec -out example.ec.key
从现有私钥创建 CSR

┌──[root@vms.154.liruilongs.github.io]-[/etc/pki/nginx]
└─$openssl req -new -key ./private/server.key -out server.csr -subj "/CN=192.168.26.1"
在单个命令中创建没有密码短语的 CSR 和私钥:
openssl req -nodes -newkey rsa:[bits] -keyout example.key -out example.csr
在命令行上提供 CSR 主题信息,而不是通过交互式提示。
openssl req -nodes -newkey rsa:[bits] -keyout example.key -out example.csr -subj "/C=UA/ST=Kharkov/L=Kharkov/O=Super Secure Company/OU=IT Department/CN=example.com"
从现有证书和私钥创建 CSR:
openssl x509 -x509toreq -in cert.pem -out example.csr -signkey example.key
通过提供 openssl 配置文件为多域 SAN 证书生成 CSR:
openssl req -new -key example.key -out example.csr -config req.conf
配置文件 req.conf:
[req]
prompt=no
default_md = sha256
distinguished_name = dn
req_extensions = req_ext
[dn]
CN=example.com
[req_ext]
subjectAltName= @alt_names
[alt_names]
DNS.1=example.com
DNS.2=www.example.com
DNS.3=ftp.example.com
生成证书,使用现有的 CSR 和私钥创建自签名证书:
┌──[root@vms.154.liruilongs.github.io]-[/etc/pki/nginx]
└─$openssl x509 -req -days 3650 -in server.csr -signkey ./private/server.key -out server.crt
Signature ok
subject=/CN=192.168.26.1
Getting Private key
┌──[root@vms.154.liruilongs.github.io]-[/etc/pki/nginx]
└─$ls
private server.crt server.csr
┌──[root@vms.154.liruilongs.github.io]-[/etc/pki/nginx]
└─$
这里也可以从头开始创建自签名证书和新私钥:
openssl req -nodes -newkey rsa:2048 -keyout example.key -out example.crt -x509 -days 365
使用您自己的“CA”证书及其私钥签署子证书。如果您是一家 CA 公司,这将显示一个关于如何颁发新证书的非常简单的示例。
openssl x509 -req -in child.csr -days 365 -CA ca.crt -CAkey ca.key -set_serial 01 -out child.crt
打印证书的文本表示
openssl x509 -in server.crt -text -noout
将证书的指纹打印为 md5、sha1、sha256 摘要:
openssl x509 -in cert.pem -fingerprint -sha256 -noout
验证 CSR 签名:
openssl req -in example.csr -verify
验证私钥是否与证书和 CSR 匹配:
openssl rsa -noout -modulus -in example.key | openssl sha256
openssl x509 -noout -modulus -in example.crt | openssl sha256
openssl req -noout -modulus -in example.csr | openssl sha256
验证证书,前提是您在计算机上将根证书和任何中间证书配置为受信任:
openssl verify example.crt
当您有中间证书链时,验证证书。根证书不是捆绑包的一部分,应该在您的机器上配置为受信任的。
openssl verify -untrusted intermediate-ca-chain.pem example.crt
验证证书,当您有中间证书链和根证书时,未配置为受信任的证书。
openssl verify -CAFile root.crt -untrusted intermediate-ca-chain.pem child.crt
验证远程服务器提供的证书是否涵盖给定的主机名。有助于检查您的多域证书是否正确涵盖了所有主机名。
openssl s_client -verify_hostname www.example.com -connect example.com:443
