""keytool" Importing Maria's Certificate Signed by CA
This section provides a tutorial example on how to import a certificate signed by a CA using 'OpenSSL' into a 'keystore' file using 'keytool'
After importing CA's certificate (Herong's certificate), Maria should import her own certificate
which was signed by the CA (Herong) using the "keytool -importcert" command
as shown below:
>keytool -importcert -alias maria_crt -keypass keypass
-file maria.crt -keystore maria.jks -storepass jkspass
Certificate was added to keystore
The command was the same one used to import CA's certificate. But this time, "keytool" did not
ask Maria to trust this certificate or not. It looks like "keytool" did a validation and
found that Maria's certificate was signed by a trusted certificate, herong_crt, in the keystore.
Want to see what's in the keystore file now?
Try this "keytool -list" command:
>keytool -list -keystore maria.jks -storepass jkspass
Keystore type: JKS
Keystore provider: SUN
Your keystore contains 3 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...
maria_crt, Apr 1, 2007, trustedCertEntry,
Certificate fingerprint (MD5): 5B:AB:DC:62:6E:F4:F4:96:5...
By now, Maria has everything she needs in her 'keystore' file to perform a digital signature on anything.
Receiver of her digital signature can trust her signature, because I, as a CA, signed her certificate.
