An SSL encryption option is provided to disable weak ciphers. 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 NOTE: If SSL encryption is set to 256-bit or higher, the cryptography settings for your virtual machine environment (JVM, IcedTea) may require installing the Unlimited Strength Java Cryptography Extension Policy Files to permit usage of iDRAC plugins such as vConsole with this level of encryption. For information about installing the policy files, see the documentation for Java. 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. NOTE: While accessing iDRAC web interface through FQDN, Mozilla Firefox may not recognize the SSL certificate as trusted. To continue, add the certificate to the trusted list. 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 upload for multiple iDRACs and all the iDRACs are trusted by the supported browsers. While connecting to iDRAC Web interface using a supported browser that supports a wildcard certificate, the iDRAC is trusted by the browser. While launching viewers, the iDRACs are trusted by the viewer clients.

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. An SSL encryption option is provided to disable weak ciphers. 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
NOTE:
If SSL encryption is set to 256-bit or higher, the cryptography settings for your virtual machine environment
(JVM, IcedTea) may require installing the Unlimited Strength Java Cryptography Extension Policy Files to permit usage
of iDRAC plugins such as vConsole with this level of encryption. For information about installing the policy files, see the
documentation for Java.
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.
NOTE:
While accessing iDRAC web interface through FQDN, Mozilla Firefox may not recognize the SSL certificate as
trusted. To continue, add the certificate to the trusted list.
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 upload for multiple
iDRACs and all the iDRACs are trusted by the supported browsers. While connecting to iDRAC Web interface using a supported browser
that supports a wildcard certificate, the iDRAC is trusted by the browser. While launching viewers, the iDRACs are trusted by the viewer
clients.
