keytool和openssl生成的证书转换

keytool和openssl生成的证书转换

keytool生成证书示例

生成私钥+证书:
keytool -genkey -alias client -keysize 2048 -validity 3650 -keyalg RSA -dname "CN=localhost" -keypass $client_passwd -storepass $client_passwd -keystore ClientCert.jks
生成文件文件ClientCert.jks。


导出证书:

~/tmp/cert# keytool -export -alias client -keystore ClientCert.jks -storepass $client_passwd -file ClientCert.crt
Certificate stored in file <ClientCert.crt>
~/tmp/cert# ll
total 8
-rw-r--r-- 1 root root  715 Jun 14 20:24 ClientCert.crt
-rw-r--r-- 1 root root 2066 Jun 14 20:21 ClientCert.jks

keytool工具不支持导出私钥。

openssl生成证书示例

生成公钥私钥:

~/tmp/cert# openssl genrsa -des3 -out private.pem 1024
Generating RSA private key, 1024 bit long modulus
.............................++++++
...........++++++
e is 65537 (0x10001)

-rw-r--r-- 1 root root 963 Jun 14 20:27 private.pem

创建证书请求:

~/tmp/cert# openssl req -subj "/C=CN/ST=BJ/L=BJ/O=HW/OU=HW/CN=CL/emailAddress=xxx@xxx.com" -new -out cert.csr -key private.pem
Enter pass phrase for private.pem:

-rw-r--r-- 1 root root 664 Jun 14 20:43 cert.csr
-rw-r--r-- 1 root root 963 Jun 14 20:27 private.pem

自签发证书:

~/tmp/cert# openssl x509 -req -in cert.csr -out public.crt -outform pem  -signkey private.pem -days 3650
Signature ok
subject=/C=CN/ST=BJ/L=BJ/O=HW/OU=HW/CN=CL/emailAddress=xxx@xxx.com

-rw-r--r-- 1 root root 963 Jun 14 20:27 private.pem
-rw-r--r-- 1 root root 871 Jun 14 20:44 public.crt

转换

keytool和openssl生成的证书相互之间无法识别,keytool生成的为jsk文件,openssl默认生成的为PEM格式文件。需要先转换成pkcs12格式,然后再使用对方的命令转换成需要的格式。

keytool生成的证书转换为PEM格式

~/tmp/cert# keytool -importkeystore -srcstoretype JKS -srckeystore ServerCert.jks -srcstorepass 123456 -srcalias server -srckeypass 123456 -deststoretype PKCS12 -destkeystore client.p12 -deststorepass 123456 -destalias client -destkeypass 123456 -noprompt

-rw-r--r-- 1 root root  963 Jun 14 20:27 private.pem
-rw-r--r-- 1 root root  871 Jun 14 20:44 public.crt
-rw-r--r-- 1 root root 1372 Jun 14 20:57 ServerCert.jks
-rw-r--r-- 1 root root 1682 Jun 14 20:55 server.p12

导出证书:

~/tmp/cert# openssl pkcs12 -in client.p12 -passin pass:$passwd -nokeys -out client.pem
MAC verified OK

导出私钥:

~/tmp/cert# openssl pkcs12 -in client.p12 -passin pass:$passwd -nocerts -out client.crt
MAC verified OK
Enter PEM pass phrase:

PEM格式证书转换为jks文件

转换为pkcs12格式:

~/tmp/cert# openssl pkcs12 -export -in public.crt -inkey private.pem -out server.p12 -name server -passin pass:${passwd} -passout pass:${passwd}
~/tmp/cert# ll
total 16
-rw-r--r-- 1 root root  664 Jun 14 20:43 cert.csr
-rw-r--r-- 1 root root  963 Jun 14 20:27 private.pem
-rw-r--r-- 1 root root  871 Jun 14 20:44 public.crt
-rw-r--r-- 1 root root 1682 Jun 14 20:55 server.p12

导入到jks中:

~/tmp/cert# keytool -importkeystore -srckeystore server.p12 -srcstoretype PKCS12 -srcstorepass ${passwd} -alias server -deststorepass ${passwd} -destkeypass ${passwd} -destkeystore ServerCert.jks
~/tmp/cert# ll

-rw-r--r-- 1 root root  963 Jun 14 20:27 private.pem
-rw-r--r-- 1 root root  871 Jun 14 20:44 public.crt
-rw-r--r-- 1 root root 1372 Jun 14 20:57 ServerCert.jks
-rw-r--r-- 1 root root 1682 Jun 14 20:55 server.p12
