Difference between Certificate and Key

[itabhishek9]

Hi SDNites,

I am trying to upload a certificate and it is not being uploaded. Can you please let me know,

1. What is the difference between Certificate and Key as I can see 2 type of entries in NWA which is Certificates and Private Key.

2. How do I create an entry of type Certificate and how do I create entry of type Key.

3. When creating entry of either type which option should be selected (X.509 / PKCS#12 / PKCS#8)

Regards,

Abhi

The certificate is the public part that you exchange with other parties (for SSL and signature verification) and the key is the private part that you never divulge. The key is used for digital signing and SSL handshaking.

You can either:

a) Generate a key and certificate in the Netweaver keystore. You then generate a CSR, send it to a CA for signing and then import the response back into the keystore view

or

b) Generate a key and certificate via another PKI and have it signed. You'll then get a PKCS file to import into the keystore which will store the key and certificate. The keystore will prompt you for the password that was set for the key

X.509 is a certificate format (https://en.wikipedia.org/wiki/X.509)

Hope this clarifies the difference for you.

Abhishek,

1. In NWA key storage, Certificate = Public Key + Additional Info

    Key = Private Key

    For encryption both public key and private key are required.

3. There are certificate/key file format you can choose any specific to your requirement.

    If you are testing, you can start with X.509
