This should have all been in the guide, but let me break this down for you so you can understand what you did. This command isn’t a simple copy and paste command. It has things you have to make decisions on and understand why you make those decisions:
C:\\> keytool -genkey -keystore my\_key.keystore -alias myApp -keyalg RSA -key size 2048 -validity 9999999
The C:\> tells me you ran this command while having the root folder. This will be important in a minute.
C:\\> keytool -genkey -keystore my\_key.keystore -alias myApp -keyalg RSA -key size 2048 -validity 9999999
This runs a program called keytool with the instruction to generate a key ( -genkey )
C:\\> keytool -genkey -keystore my\_key.keystore -alias myApp -keyalg RSA -key size 2048 -validity 9999999
This tells the program to name the keystore " my_key.keystore" but since you didn’t provide a path as part of the file name, the keystore was output to *C:* This is where you will find your keystore.
C:\\> keytool -genkey -keystore my\_key.keystore -alias myApp -keyalg RSA -key size 2048 -validity 9999999
Keystore store files can contain multiple keystores. Each keystore is identified by an alias. In this case you named it myApp. The rest is someone standard copy/pastes stuff.
All of this assumes you ran this from C:\ and you just prepended the path to the keystore to the command. You should be able to hit the browse button, navigate to c:\ and you should find my_keystore.keystore file located there. Open that, then enter your passwords.
Had you done a CD command and changed your directory to where the bin folder, then that’s where your keystore is.
