Arguments¶
name
Name for the SSL profile. Must begin with an ASCII alphanumeric or underscore (_) character, and must contain only ASCII alphanumeric, underscore, hash (#), period (.), space, colon (:), at (@), equals (=), and hyphen (-) characters. Cannot be changed after the profile is created.
sslProfileType
Type of profile. Front end profiles apply to the entity that receives requests from a client. Backend profiles apply to the entity that sends client requests to a server.
Possible values: BackEnd, FrontEnd
Default value: FrontEnd
dhCount
Number of interactions, between the client and the NetScaler appliance, after which the DH private-public pair is regenerated. A value of zero (0) specifies infinite use (no refresh).
This parameter is not applicable when configuring a backend profile.
Minimum value: 0
Maximum value: 65534
dh
State of Diffie-Hellman (DH) key exchange.
This parameter is not applicable when configuring a backend profile.
Possible values: ENABLED, DISABLED
Default value: DISABLED
dhFile
Name for and, optionally, path to the PEM-format DH parameter file to be installed. /nsconfig/ssl/ is the default path.
This parameter is not applicable when configuring a backend profile.
eRSA
State of Ephemeral RSA (eRSA) key exchange. Ephemeral RSA allows clients that support only export ciphers to communicate with the secure server even if the server certificate does not support export clients. The ephemeral RSA key is automatically generated when you bind an export cipher to an SSL or TCP-based SSL virtual server or service. When you remove the export cipher, the eRSA key is not deleted. It is reused at a later date when another export cipher is bound to an SSL or TCP-based SSL virtual server or service. The eRSA key is deleted when the appliance restarts.
This parameter is not applicable when configuring a backend profile.
Possible values: ENABLED, DISABLED
Default value: ENABLED
eRSACount
Refresh count for regeneration of RSA public-key and private-key pair. Zero (0) specifies infinite usage (no refresh).
This parameter is not applicable when configuring a backend profile.
Minimum value: 0
Maximum value: 65534
sessReuse
State of session reuse. Establishing the initial handshake requires CPU-intensive public key encryption operations. With the ENABLED setting, session key exchange is avoided for session resumption requests received from the client.
Possible values: ENABLED, DISABLED
Default value: ENABLED
sessTimeout
Time, in seconds, for which to keep the session active. Any session resumption request received after the timeout period will require a fresh SSL handshake and establishment of a new SSL session.
Minimum value: 0
Maximum value: 4294967294
cipherRedirect
State of Cipher Redirect. If this parameter is set to ENABLED, you can configure an SSL virtual server or service to display meaningful error messages if the SSL handshake fails because of a cipher mismatch between the virtual server or service and the client.
This parameter is not applicable when configuring a backend profile.
Possible values: ENABLED, DISABLED
Default value: DISABLED
cipherURL
URL of the page to which to redirect the client in case of a cipher mismatch. Typically, this page has a clear explanation of the error or an alternative location that the transaction can continue from.
This parameter is not applicable when configuring a backend profile.
clientAuth
State of client authentication. In service-based SSL offload, the service terminates the SSL handshake if the SSL client does not provide a valid certificate.
This parameter is not applicable when configuring a backend profile.
Possible values: ENABLED, DISABLED
Default value: DISABLED
clientCert
Type of client authentication. If this parameter is set to MANDATORY, the appliance terminates the SSL handshake if the SSL client does not provide a valid certificate. With the OPTIONAL setting, the appliance requests a certificate from the SSL clients but proceeds with the SSL transaction even if the client presents an invalid certificate.
This parameter is not applicable when configuring a backend SSL profile.
Caution: Define proper access control policies before changing this setting to Optional.
Possible values: Mandatory, Optional
dhKeyExpSizeLimit
This option enables the use of NIST recommended (NIST Special Publication 800-56A) bit size for private-key size. For example, for DH params of size 2048bit, the private-key size recommended is 224bits. This is rounded-up to 256bits.
Possible values: ENABLED, DISABLED
Default value: DISABLED
sslRedirect
State of HTTPS redirects for the SSL service.
For an SSL session, if the client browser receives a redirect message, the browser tries to connect to the new location. However, the secure SSL session breaks if the object has moved from a secure site (https://) to an unsecure site (http://). Typically, a warning message appears on the screen, prompting the user to continue or disconnect.
If SSL Redirect is ENABLED, the redirect message is automatically converted from http:// to https:// and the SSL session does not break.
This parameter is not applicable when configuring a backend profile.
Possible values: ENABLED, DISABLED
Default value: DISABLED
redirectPortRewrite
State of the port rewrite while performing HTTPS redirect. If this parameter is set to ENABLED, and the URL from the server does not contain the standard port, the port is rewritten to the standard.
Possible values: ENABLED, DISABLED
