Trust Store tabs

The Trust Stores contain signed and trusted root certificates with their public keys. These stores contain no private keys. A Trust Store supports the client side of the relationship by using its root CA certificates to verify the signatures of the certificates it receives from each server. If a client cannot validate a server certificate’s signature, an error message allows you to approve or reject a security exemption (on the Allowed Hosts tab).

The System Trust Stores contain installed signed certificates by trusted entities (CA authorities) recognized by the Java Runtime Engine (JRE) of the currently opened platform. A User Trust Store contains installed signed certificates by trusted entities that you have imported (your own certificates).

Only certificates with public keys are stored in the Trust Stores. The majority of certificates in the System Trust Store come from the JRE. You add your own certificates to a User Trust Store by importing them.

Feel free to pass out such root certificates to your team; share them with your customers; make sure that any client that needs to connect to one of your servers has the server’s root certificate in its client Trust Store.

Trust Store columns


Column	Description
Alias	Identifies the entity that signed the certificate.
Issued By	Identifies the entity that signed the certificate.
Subject	Specifies the Distinguished Name, the name of the company that owns the certificate.
Not Before	Specifies the date before which the certificate is not valid. This date on a server certificate should not be earlier than the Not Before date on the CA certificate used to sign it.
Not After	Specifies the expiration date for the certificate. This date on a server certificate should not be later than the Not After date on the CA certificate used to sign it. A period no longer than a year ensures regular certificate changes making it more likely that the certificate contains the latest cryptographic standards, and reducing the number of old, neglected certificates that can be stolen and re-used for phishing and drive-by malware attacks. Changing certificates more frequently is even better.
Key Algorithm	Refers to the cryptographic formula used to calculate the certificate keys.
Key Size	Specifies the size of the keys in bits. Four key sizes are allowed: 1024 bits, 2048 bits (this is the default), 3072 bits, and 4096 bits. Larger keys take longer to generate but offer greater security.
Signature Algorithm	Specifies the cryptographic formula used to sign the certificate.
Signature Size	Specifies the size of the signature.
Valid	Specifies certificate dates.
Self Signed	Indicates that the certificate was signed with its own private key.

Trust Store buttons

The Delete and Import buttons are available only in a User Trust Store.

User Key Store buttons

View displays details for the selected item.
Delete removes the selected record from the database.
Import adds an imported item to the database.
Export saves a copy of the selected record to the hard disk.

For certificates, the file extension is .pem.
