Gnetrate CSR for tomcat Ecdsa in cisco unity with different key length

[Redash6174183]

Dear team,

I am trying generate CSR for Tomcat ECDSA however the available key length are not supported by our internal CA.

Available key size are 256 ,382,521 and the CA requires 2048

please advise if there is other way to generate the CSR with length 2048 like from CLI

The key length for Elliptic Curve certificates is different than for RSA signed certificates. 2048 is likely the requires key length for RSA. In the CA you use there need to be a profile that should be used to sign the EC certificate(s). See this link for additional details on key sizes in EC. https://en.wikipedia.org/wiki/Elliptic-curve_cryptography#Key_sizes
