Do RSA private keys expire?
The RSA private/public key does not have dates, so it does not expire. RSA private/public keys are used for asymmetric cryptography operations. X509 certificates use a private key to “sign” the certificate so that the corresponding public key can be used to verify that the data in the certificate has not been tampered with.
