Manage Certificates (MEKeyTool)

MEKeyTool manages the public keys of certificate authorities (CAs), making it functionally similar to the keytool utility that comes with the Java SE SDK. The keys can be used to facilitate secure HTTP communication over SSL (HTTPS).

Before using MEKeyTool, you must first have access to a Java Cryptography Extension keystore. You can create one using the Java SE keytool utility.



Mac OS and Linux


To run MEKeyTool, open a command prompt, change the current directory to installdir/bin, and enter the following command:

installdir\bin\mekeytool.exe -command
Mac OS:
installdir/Contents/Resources/bin/mekeytool -command

The command keywords follow.

The Java ME Platform SDK contains a default ME keystore called _main.ks, which is located in:


This keystore includes all the certificates that exist in the default Java SE platform keystore that comes with the Java SE installation.

Also, each emulator instance has its own _main.ks file located in userhome/javame-sdk/3.0/work/emulator-instance-id/appdb.If you do not specify a value for MEkeystore, a new key is added to the default ME key for this emulator instance.

If you do not specify a value for -keystore, the default keystore is used:


C:\Documents and Settings\user\.keystore.ks
