"keytool" Importing CA's Own Certificate

This section provides a tutorial example on how to import CA's certificate generated by 'OpenSSL' into a 'keystore' file using 'keytool'

When Maria receives my CA self-signed public key certificate file, she needs to imported it into her keystore file with the "keytool -importcert" command as shown below:

C:\herong>keytool -importcert -alias herong_crt -keypass keypass 
-file herong.crt -keystore maria.jks -storepass jkspass

Trust this certificate? [no]:  yes
Certificate was added to keystore

Notes on what Maria did:

Want to see if the certificate was imported correctly or not? Try this "keytool -list" command:

C:\herong>keytool -list -keystore maria.jks -storepass jkspass

Keystore type: JKS
Keystore provider: SUN

Your keystore contains 2 entries

maria_key, Apr 1, 2007, PrivateKeyEntry,
Certificate fingerprint (MD5): 54:5A:E8:77:30:82:B4:EB:C...
herong_crt, Apr 1, 2007, trustedCertEntry,
Certificate fingerprint (MD5): C1:6C:FE:38:F7:0F:71:23:3...

As we can see, my CA certificate was imported ok and stored as a "trustedCertEntry". So certificates generated by "OpenSSL" is compatible with "keytool" certificate format.

If Maria made a mistake when import my certificate, she could use this command to delete my certificate from her keystore file:

C:\herong>keytool -delete -alias herong_crt -keystore maria.jks 
-storepass jkspass

Now Maria is ready to import her own public key certificate signed by me as described in the next section.
