HP 640n Print Server Certificate Validity Period, Encryption Key Length, Certificate Information

Table 4-16Certificate configuration screens (continued)

●Update Pre-Installed Certificate Update the pre-installed, self-signed certificate. The certificate is overwritten. You can update the following items:

Certificate Validity Period

The browser identifies the certificate as self-signed for each new Web session, which can cause a security alert message. You can bypass this message by adding the certificate to the browser's certificate store or by disabling browser alerts (not recommended).

Self-signed certificates are not necessarily secure because the certificate owner is merely confirming his own identity instead of verification by a trusted third party. Certificates from a trusted third party are considered more secure.

Encryption Key Length

Select whether to use 1024 bit or 2048 bit encryption key length.
