What can a RSA key be used for?
What is an RSA key used for? RSA key is a private key based on RSA algorithm. Private Key is used for authentication and a symmetric key exchange during establishment of an SSL/TLS session. It is a part of the public key infrastructure that is generally used in case of SSL certificates.
How to exchange public and private RSA keys?
To begin with, Alice creates a RSA public/private key pair and extracts the public key. Bob does the same (his files will be named bob-*) (VULN-1). Now both Alice and Bob publish their public keys on their facebook page. Anyone can read them. Now Alice wants to exchange a private conversation with Bob, maybe some files.
Why do Alice and Bob use RSA for authentication?
And since nobody else except Alice and Bob are now privy to the random token that has been exchanged, both Alice and Bob may use it as the key to a symmetric cypher algorithm suitable for exchanging further communication (they might also use again RSA, but it’s more expensive computationally):
How are public keys used in SSL certificates?
It is a part of the public key infrastructure that is generally used in case of SSL certificates. A public key infrastructure assumes asymmetric encryption where two types of keys are used: Private Key and Public Key (it is included in an SSL certificate).
How to assign private key to a new certificate after you?
SerialNumber is the serial number that you wrote down in step 17. In the Certificates snap-in, right-click Certificates, and then select Refresh. The certificate now has an associated private key. You can now use the IIS MMC to assign the recovered keyset (certificate) to the web site that you want.
Is it a good practice to change your private key?
Changing the private key is not a best practice, it is a widespread practice; it has in fact very little to do with security, and a lot to do with how common CA handle certificate renewals, i.e. most of the time like a new certificate, with a new private key generation.
How often does a https symmetric key need to be renewed?
The key would be renewed exactly as often as the client and server wish it — i.e., in practice, only when either the client or the server reboots.
