z10 HMC can create certificate key longer than 2048 bits

z10 HMC remote console need to use SSL service and a SSL certificate. To create a self-signed certificate from z10 "certificate management" menu can use not enough safe.
At least one of the X.509 certificates sent by the remote host has a key that is shorter than 2048 bits. According to industry standards set by the Certification Authority/Browser (CA/B) Forum, certificates issued after January 1, 2014 must be at least 2048 bits. Some browser SSL implementations may reject keys less than 2048 bits after January 1, 2014. Additionally, some SSL certificate vendors may revoke certificates less than 2048 bits before January 1, 2014. Note that Nessus will not flag root certificates with RSA keys less than 2048 bits if they were issued prior to December 31, 2010, as the standard considers them exempt.
Need to replace the certificate in the chain with the RSA key less than 2048 bits in length with a longer key, and reissue any certificates signed by the old certificate.

    After a closer look, the request appears to not fall within an RDz feature request. Rejecting as suggested by the submitter.
