Quote:
If you have a requirement to use larger key sizes for your personal certificates, you cannot renew an existing certificate. You must replace your existing key by following the steps described in Requesting a personal certificate on AIX, Linux, and Windows to create a new certificate request that uses the key sizes you require.


Does this refer to renewing a cert, and specifying a larger key size that the original cert (not sure if this is possible), or just that certs with larger key sizes cannot be renewed? (in which case, what is a larger key size? 2048 bits? 4096?)
