Make Java Applet signature verification
2004-03-29 15:33:23
If the Java applet written by applet If there is no signature, then the access client program will be subject to safety restrictions; how to pay attention to the Java small program signature, there are also these aspects available for reference, but they are not complete Here I give a specific operational document, I hope to give you some help. Scenario: Test.jar: After signature Java small program results: After signing, the client can automatically download the Java applet, and the Java applet can access any resource of the client: (1) Package Java applet
Jar CVF Test.jar Test.class
(2) Generate a keystore named chinani.Store, alias for chinani
Keytool -Genkey-Keystore chinani.Store -Alias chinani
Password: 123456 (Input as needed) If you need it as needed, finally confirm: y (3) Export CHINANI.CER Digital Certificate
Keytool -Export-Keystore chinani.Store -Alaias chinani -file chinani.cer
Password: 123456 (input as needed) (4) Signing Test.jar files
Jarsigner -keystore chinani.store test.jar chinani
Password: 123456 (Enter it according to need) Finally write an HTML file, run this file to automatically download and install the Java applet
