Generate a Digital Certificate Signing Request

Availability: This command is available to cluster and Vserver administrators at the admin privilege level.

Description

This command generates a digital certificate signing request and displays it on the console. A certificate signing request (CSR or certification request) is a message sent to a certificate authority (CA) to apply for a digital identity certificate.

Parameters

[-common-name <text>] - FQDN or Custom Common Name

This specifies the desired certificate name as a fully qualified domain name (FQDN) or custom common name or the name of a person. The supported characters, which are a subset of the ASCII character set, are as follows:

Letters a through z, A through Z
Numbers 0 through 9
Asterisk (*), period (.), underscore (_) and hyphen (-)

The common name must not start or end with a "-" or a ".". The maximum length is 253 characters.

{ [-size <size of requested certificate in bits>] - (DEPRECATED)-Size of Requested Certificate in Bits

This specifies the number of bits in the private key. A larger size value provides for a more secure key. The default is 2048. Possible values include 512 , 1024 , 1536 , and 2048 .

This parameter has been deprecated in ONTAP 9.8 and may be removed in future releases of Data ONTAP. Use the security-strength parameter instead.

| [-security-strength <bits of security strength>] - Security Strength in Bits }

Use this parameter to specify the minimum security strength of the certificate in bits. The security bits mapping to RSA and ECDSA key length, in bits, are as follows:

            Size      RSA Key Length       Elliptic Curve Key Length
            112       2048                 224
            128       3072                 256
            192       4096                 384

Note: FIPS supported values are restricted to 112 and 128. For ECDSA, TLSv1.3 requires key length of 256 or greater.

[-algorithm <Asymmetric key generation algorithm>] - Asymmetric Encryption Algorithm

Use this parameter to specify the asymmetric encryption algoithm to use for generating the public/private key for the certificate signing request. Algorithm values can be RSA or EC. Default value is RSA.

[-country <text>] - Country Name

This specifies the country where the Vserver resides. The country name is a two-letter code. The default is US. Here is the list of country codes:
Country Codes

[-state <text>] - State or Province Name

This specifies the state or province where the Vserver resides.

[-locality <text>] - Locality Name

This specifies the locality where the Vserver resides. For example, the name of a city.

[-organization <text>] - Organization Name

This specifies the organization where the Vserver resides. For example, the name of a company.

[-unit <text>] - Organization Unit

This specifies the unit where the Vserver resides. For example, the name of a section or a department within a company.

[-email-addr <mail address>] - Contact Administrator's Email Address

This specifies the email address of the contact administrator for the Vserver.

[-hash-function <hashing function>] - Hashing Function

This specifies the cryptographic hashing function for signing the certificate. The default is SHA256. Possible values include SHA224 , SHA256 , SHA384 , and SHA512 .

[-key-usage <Certificate key usage extension>,…] - Key Usage Extension

Use this parameter to specify the key usage extension values. The default values are: digitalSignature , keyEncipherment . Possible values include:

digitalSignature
nonRepudiation
keyEncipherment
dataEncipherment
keyAgreement
keyCertSigning
cRLSigning
encipherOnly
decipherOnly
critical

[-extended-key-usage <Certificate extKeyUsage extension>,…] - Extended Key Usage Extension

Use this parameter to specify the extended key usage extension values. The default values are: serverAuth , clientAuth . Possible values include:

serverAuth
clientAuth
codeSigning
emailProtection
timeStamping
OCSPSigning
critical

[-rfc822-name <mail address>,…] - Email Address SAN

Use this parameter to specify the Subject Alternate Name extension - a list of rfc822-names (email addresses).

[-uri <text>,…] - URI SAN

Use this parameter to specify the Subject Alternate Name extension - a list of URIs.

[-dns-name <text>,…] - DNS Name SAN

Use this parameter to specify the Subject Alternate Name extension - a list of DNS names.

[-ipaddr <IP Address>,…] - IP Address SAN

Use this parameter to specify the Subject Alternate Name extension - a list of IP addresses.

Examples

This example creates a certificate-signing request with a 2048-bit RSA private key generated by the SHA256 hashing function for use by the Engineering group in IT at a company whose custom common name is www.example.com , located in Durham, NC, USA. The email address of the contact administrator who manages the Vserver is web@example.com The request also specifies the subject alternative names, key-usage and extended-key-usage extensions.
