keytool - generate new *.jks file (Java KeyStore repository)
9 points
In this short article we would like to show how to generate *.jks file that stores security certificates as Java KeyStore repositoiry.
Quick solution (run following command):
xxxxxxxxxx1
keytool -genkey -keyalg RSA -alias my_key_alias -keystore my_keystore.jks -storepass my_secret_password -validity 3650 -keysize 2048
In more clear version:
xxxxxxxxxx1
keytool \2
-genkey \3
-keyalg RSA \4
-alias my_key_alias \5
-keystore my_keystore.jks \6
-storepass my_secret_password \7
-validity 3650 \8
-keysize 2048Where:
-genkey | runs tool in key generation mode |
-keyalg RSA | sets RSA used as key algorithm |
-alias my_key_alias | sets unique allias that helps to access to keys and trusted certificate entries inside created KeyStore |
-keystore my_keystore.jks | sets path where Java KeyStore file is saved |
-storepass my_secret_password | sets password that protects access to store |
-validity 3650 |
sets amount for days when generated certificates expires |
-keysize 2048 | sets size of gnererated keys |
Note: under Windows to get access to
keytoolit could be necessary to use full path.
JKD 11 keytool command example:
xxxxxxxxxx1
"C:\Program Files\Java\jdk-11.0.2\bin\keytool.exe" -genkey -keyalg RSA -alias my_key_alias -keystore my_keystore.jks -storepass my_secret_password -validity 3650 -keysize 2048
In more clear version:
xxxxxxxxxx1
"C:\Program Files\Java\jdk-11.0.2\bin\keytool.exe" \2
-genkey \3
-keyalg RSA \4
-alias my_key_alias \5
-keystore my_keystore.jks \6
-storepass my_secret_password \7
-validity 3650 \8
