Certificates Generate Public and Private Key Sign the Public Key with a CA Private Key Append the Cert to the Private Key

Lets See a Cert In P12 format they are Binary, but we can use openSSL to convert to ASCII Here is the command: openssl pkcs12 -in Default\ Device.p12 -out certfile2.pem - passin pass:b298b12b d- b3c9-f6f639b5de66

Let'sSee a Cert Part BEGIN ENCRYPTED PRIVATE KEY----- MIICxjBABgkqhkiG9w0BBQ0wMzAbBgkqhkiG 9w0BBQwwDgQIRVkHt5ym+dYCAggA MBQGCCqGSIb3DQMHBAglTFlPoHcELQSC AoCLMCzUhF9ezDFwTiM5jsgRJDLXcfyK tcj6zRLc40QKu/hUjMj5kF+T52qwr ….. … BEGIN CERTIFICATE----- MIIDaDCCAlCgAwIBAgIGAUwFJmdtMA0GCS qGSIb3DQEBBQUAMHMxCzAJBgNVBAYT AlVTMQswCQYDVQQIDAJNRDEPMA0GA1U ECgwGU3RyZWl0MQ8wDQYDVQQLDAZTdH Jl aXQxJDAiBgkqhkiG

So Let's Talk About the Cert We started with a public key and a private key. We also started with another private key called a “Certificate Authority” private key We sign the public key with the Certificate Authority Private key making it a certificate. We append the Private Key and the Certificate create a P12 certificate.

How is it Used Client: Send Cert Server: Cert Received And unlocked with CA Private Key Leaving the public key Client Sends Private Key Server Receives the Private Key and makes sure that it Associated with the Public Key from the Previous Step

This is 2-Way SSL Uses Asymmetric Encryption Is uses as part of an Identity Assertion The Certificate is actually a public key private key pair. The Public Key is signed with the Certificate Authority private key (CA).

The CA The CA is the overriding private key for 2- way SSL and cannot be given out. It must be protected. It ends up in a truststore because the truststore is used in the 2-way SSL Handshake Keystores are used for 1 way SSL Truststores are used for 2 way SSL
