SSL server certificates
iDRAC includes a Web server that is configured to use the industry-standard SSL security protocol to transfer encrypted data over
a network. Built upon asymmetric encryption technology, SSL is widely accepted for providing authenticated and encrypted
communication between clients and servers to prevent eavesdropping across a network.
An SSL-enabled system can perform the following tasks:
• Authenticate itself to an SSL-enabled client
• Allow the two systems to establish an encrypted connection
The encryption process provides a high level of data protection. iDRAC employs the 128-bit SSL encryption standard, the most
secure form of encryption generally available for Internet browsers in North America.
iDRAC Web server has a Dell self-signed unique SSL digital certificate by default. You can replace the default SSL certificate with a
certificate signed by a well-known Certificate Authority (CA). A Certificate Authority is a business entity that is recognized in the
Information Technology industry for meeting high standards of reliable screening, identification, and other important security criteria.
Examples of CAs include Thawte and VeriSign. To initiate the process of obtaining a CA-signed certificate, use either iDRAC Web
interface or RACADM interface to generate a Certificate Signing Request (CSR) with your company's information. Then, submit the
generated CSR to a CA such as VeriSign or Thawte. The CA can be a root CA or an intermediate CA. After you receive the CA-
signed SSL certificate, upload this to iDRAC.
For each iDRAC to be trusted by the management station, that iDRAC's SSL certificate must be placed in the management station's
certificate store. Once the SSL certificate is installed on the management stations, supported browsers can access iDRAC without
certificate warnings.
You can also upload a custom signing certificate to sign the SSL certificate, rather than relying on the default signing certificate for
this function. By importing one custom signing certificate into all management stations, all the iDRACs using the custom signing
certificate are trusted. If a custom signing certificate is uploaded when a custom SSL certificate is already in-use, then the custom
SSL certificate is disabled and a one-time auto-generated SSL certificate, signed with the custom signing certificate, is used. You
can download the custom signing certificate (without the private key). You can also delete an existing custom signing certificate.
After deleting the custom signing certificate, iDRAC resets and auto-generates a new self-signed SSL certificate. If a self-signed
certificate is regenerated, then the trust must be re-established between that iDRAC and the management workstation. Auto-
generated SSL certificates are self-signed and have an expiration date of seven years and one day and a start date of one day in the
past (for different time zone settings on management stations and the iDRAC).
The iDRAC Web server SSL certificate supports the asterisk character (*) as part of the left-most component of the Common
Name when generating a Certificate Signing Request (CSR). For example, *.qa.com, or *.company.qa.com. This is called a wildcard
certificate. If a wildcard CSR is generated outside of iDRAC, you can have a signed single wildcard SSL certificate that you can

How to Obtain
SHA-2 certificates are also supported.

trusted CA
NOTE: iDRAC ships with a default
self-signed SSL server certificate.
The iDRAC Web server, Virtual
Media, and Virtual Console use this
certificate.
SHA-2 certificates are also supported.
