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
ssllogProfile
The name of the ssllogprofile.
dhCount
Number of interactions, between the client and the Citrix ADC, 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. Allowed DH count values are 0 and >= 500. 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
The file name and path for the DH parameter.
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
The refresh count for the re-generation of RSA public-key and private-key pair. 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
The Session timeout value in seconds. Minimum value: 0 Maximum value: 4294967294
cipherRedirect
State of Cipher Redirect.

This parameter is not applicable when configuring a backend profile.
Possible values: ENABLED, DISABLED Default value: DISABLED
cipherURL
The redirect URL to be used with the Cipher Redirect feature.
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
The rule for client certificate requirement in client authentication.
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

Possible values: ENABLED, DISABLED Default value: DISABLED
ocspStapling
State of OCSP stapling support on the SSL virtual server. Supported only if the protocol used is higher than SSLv3. Possible values: ENABLED: The appliance sends a request to the OCSP responder to check the status of the server certificate and caches the response for the specified time. If the response is valid at the time of SSL handshake with the client, the OCSP-based server certificate status is sent to the client during the handshake.

These checks are performed only if the session is SNI enabled (i.e when vserver or profile bound to vserver has SNI enabled and 'Client Hello' arrived with SNI extension) and HTTP request contains 'Host' header. Available settings function as follows: CERT - Connection is forwarded if the 'Host' value is covered by the certificate used to establish this SSL session. STRICT - Connection is forwarded only if value of 'Host' header in HTTP is identical to the 'Server name' value passed in 'Client Hello' of the SSL connection.

Possible values: ENABLED, DISABLED Default value: DISABLED
zeroRttEarlyData
State of TLS 1.3 0-RTT early data support for the SSL Virtual Server. This setting only has an effect if resumption is enabled, as early data cannot be sent along with an initial handshake.

Possible values: ENABLED, DISABLED Default value: DISABLED
tls13SessionTicketsPerAuthContext
Number of tickets the SSL Virtual Server will issue anytime TLS 1.3 is negotiated, ticket-based resumption is enabled, and either (1) a handshake completes or (2) post-handhsake client auth completes.

Default value: 1 Minimum value: 1 Maximum value: 10
dheKeyExchangeWithPsk
Whether or not the SSL Virtual Server will require a DHE key exchange to occur when a PSK is accepted during a TLS 1.3 resumption handshake. A DHE key exchange ensures forward secrecy even in the event that ticket keys are compromised, at the expense of an additional round trip and resources required to carry out the DHE key exchange. If disabled, a DHE key exchange will be performed when a PSK is accepted but only if requested by the client. If enabled, the server will require a DHE key exchange when a PSK is accepted regardless of whether the client supports combined PSK-DHE key exchange. This setting only has an effect when resumption is enabled.
Possible values: YES, NO Default value: NO

If disabled, a DHE key exchange will be performed when a PSK is accepted but only if requested by the client. If enabled, the server will require a DHE key exchange when a PSK is accepted regardless of whether the client supports combined PSK-DHE key exchange. This setting only has an effect when resumption is enabled.
Possible values: YES, NO Default value: NO

show ssl profile¶
Display all the configured SSL profiles in the system. If a name is specified, then only that profile is shown.
Synopsis¶
show ssl profile [<name>]
Arguments¶
name
Name of the SSL profile for which to show detailed information.
Output¶
dh
State of Diffie-Hellman (DH) key exchange. This parameter is not applicable when configuring a backend profile.
dhFile
The file name and path for the DH parameter.
dhCount
Number of interactions, between the client and the Citrix ADC, 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. Allowed DH count values are 0 and >= 500.
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.
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.
eRSACount
The refresh count for the re-generation of RSA public-key and private-key pair.
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.
sessTimeout
The Session timeout value in seconds.
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.
cipherURL
The redirect URL to be used with the Cipher Redirect feature.
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.
clientCert
The rule for client certificate requirement in client authentication.
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.
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.
nonFipsCiphers
State of usage of ciphers that are not FIPS approved. Valid only for an SSL service bound with a FIPS key and certificate.
ssl3
State of SSLv3 protocol support for the SSL profile. Note: On platforms with SSL acceleration chips, if the SSL chip does not support SSLv3, this parameter cannot be set to ENABLED.
tls1
State of TLSv1.0 protocol support for the SSL profile.
tls11
State of TLSv1.1 protocol support for the SSL profile.
tls12
State of TLSv1.2 protocol support for the SSL profile.
tls13
State of TLSv1.3 protocol support for the SSL profile.
SNIEnable
State of the Server Name Indication (SNI) feature on the virtual server and service-based offload. SNI helps to enable SSL encryption on multiple domains on a single virtual server or service if the domains are controlled by the same organization and share the same second-level domain name. For example, *.sports.net can be used to secure domains such as login.sports.net and help.sports.net.
ocspStapling
State of OCSP stapling support on the SSL virtual server. Supported only if the protocol used is higher than SSLv3. Possible values: ENABLED: The appliance sends a request to the OCSP responder to check the status of the server certificate and caches the response for the specified time. If the response is valid at the time of SSL handshake with the client, the OCSP-based server certificate status is sent to the client during the handshake. DISABLED: The appliance does not check the status of the server certificate.
serverAuth
State of server authentication support for the SSL Backend profile.
commonName
Name to be checked against the CommonName (CN) field in the server certificate bound to the SSL server.
pushEncTrigger
Trigger encryption on the basis of the PUSH flag value. Available settings function as follows: * ALWAYS - Any PUSH packet triggers encryption. * IGNORE - Ignore PUSH packet for triggering encryption. * MERGE - For a consecutive sequence of PUSH packets, the last PUSH packet triggers encryption. * TIMER - PUSH packet triggering encryption is delayed by the time defined in the set ssl parameter command or in the Change Advanced SSL Settings dialog box.
sendCloseNotify
Enable sending SSL Close-Notify at the end of a transaction.
clearTextPort
Port on which clear-text data is sent by the appliance to the server. Do not specify this parameter for SSL offloading with end-to-end encryption.
insertionEncoding
Encoding method used to insert the subject or issuer's name in HTTP requests to servers.
denySSLReneg
Deny renegotiation in specified circumstances. Available settings function as follows: * NO - Allow SSL renegotiation. * FRONTEND_CLIENT - Deny secure and nonsecure SSL renegotiation initiated by the client. * FRONTEND_CLIENTSERVER - Deny secure and nonsecure SSL renegotiation initiated by the client or the Citrix ADC during policy-based client authentication. * ALL - Deny all secure and nonsecure SSL renegotiation. * NONSECURE - Deny nonsecure SSL renegotiation. Allows only clients that support RFC 5746.
quantumSize
Amount of data to collect before the data is pushed to the crypto hardware for encryption. For large downloads, a larger quantum size better utilizes the crypto resources.
strictCAChecks
Enable strict CA certificate checks on the appliance.
encryptTriggerPktCount
Maximum number of queued packets after which encryption is triggered. Use this setting for SSL transactions that send small packets from server to Citrix ADC.
pushFlag
Insert PUSH flag into decrypted, encrypted, or all records. If the PUSH flag is set to a value other than 0, the buffered records are forwarded on the basis of the value of the PUSH flag. Available settings function as follows: 0 - Auto (PUSH flag is not set.) 1 - Insert PUSH flag into every decrypted record. 2 -Insert PUSH flag into every encrypted record. 3 - Insert PUSH flag into every decrypted and encrypted record.
dropReqWithNoHostHeader
Host header check for SNI enabled sessions. If this check is enabled and the HTTP request does not contain the host header for SNI enabled sessions(i.e vserver or profile bound to vserver has SNI enabled and 'Client Hello' arrived with SNI extension), the request is dropped.
SNIHTTPHostMatch
Controls how the HTTP 'Host' header value is validated. These checks are performed only if the session is SNI enabled (i.e when vserver or profile bound to vserver has SNI enabled and 'Client Hello' arrived with SNI extension) and HTTP request contains 'Host' header. Available settings function as follows: CERT - Connection is forwarded if the 'Host' value is covered by the certificate used to establish this SSL session. STRICT - Connection is forwarded only if value of 'Host' header in HTTP is identical to the 'Server name' value passed in 'Client Hello' of the SSL connection. NO - No validation is performed on the HTTP 'Host' header value.
pushEncTriggerTimeout
PUSH encryption trigger timeout value. The timeout value is applied only if you set the Push Encryption Trigger parameter to Timer in the SSL virtual server settings.
sslTriggerTimeout
Time, in milliseconds, after which encryption is triggered for transactions that are not tracked on the Citrix ADC because their length is not known. There can be a delay of up to 10ms from the specified timeout value before the packet is pushed into the queue.
