Step by step from generating key to login: Generate the key with $ ssh-keygen -t rsa -b 2048 -v and when asked to enter file in which to save the key, type my-certificate and when asked to enter passphrase, press Enter (empty passphrase) and confirm by Enter.

Descriptionedit
You can specify one of the following modes:
ca
, cert
, csr
, http
. Theelasticsearch-certutil
command also supports a silent mode of operation toenable easier batch operations.CA modeedit
The
ca
mode generates a new certificate authority (CA). By default, itproduces a single PKCS#12 output file, which holds the CA certificate and theprivate key for the CA. If you specify the --pem
parameter, the commandgenerates a zip file, which contains the certificate and private key in PEMformat.You can subsequently use these files as input for the
cert
mode of the command.CERT modeedit
The
cert
mode generates X.509 certificates and private keys. By default, itproduces a single certificate and key for use on a single instance.To generate certificates and keys for multiple instances, specify the
--multiple
parameter, which prompts you for details about each instance.Alternatively, you can use the --in
parameter to specify a YAML file thatcontains details about the instances.An instance is any piece of the Elastic Stack that requires a TLS or SSLcertificate. Depending on your configuration, Elasticsearch, Logstash, Kibana, and Beatsmight all require a certificate and private key. The minimum requiredinformation for an instance is its name, which is used as the common name forthe certificate. The instance name can be a hostname value or a fulldistinguished name. If the instance name would result in an invalid file ordirectory name, you must also specify a file name in the
--name
commandparameter or in the filename
field in an input YAML file.You can optionally provide IP addresses or DNS names for each instance. Ifneither IP addresses nor DNS names are specified, the Elastic stack productscannot perform hostname verification and you might need to configure the
verification_mode
security setting to certificate
only. For more informationabout this setting, see Security settings.All certificates that are generated by this command are signed by a CA. You canprovide your own CA with the
--ca
or --ca-cert
parameters. Otherwise, thecommand automatically generates a new CA for you. For more information aboutgenerating a CA, see the CA mode of this command.By default, the
cert
mode produces a single PKCS#12 output file which holdsthe instance certificate, the instance private key, and the CA certificate. Ifyou specify the --pem
parameter, the command generates PEM formattedcertificates and keys and packages them into a zip file.If you specify the --keep-ca-key
, --multiple
or --in
parameters,the command produces a zip file containing the generated certificates and keys.CSR modeedit
The
csr
mode generates certificate signing requests (CSRs) that you can sendto a trusted certificate authority to obtain signed certificates. The signedcertificates must be in PEM or PKCS#12 format to work with Elasticsearchsecurity features.By default, the command produces a single CSR for a single instance. Create github ssh key.
To generate CSRs for multiple instances, specify the
--multiple
parameter,which prompts you for details about each instance. Alternatively, you can usethe --in
parameter to specify a YAML file that contains details about theinstances.The
csr
mode produces a single zip file which contains the CSRs and theprivate keys for each instance. Each CSR is provided as a standard PEMencoding of a PKCS#10 CSR. Each key is provided as a PEM encoding of an RSAprivate key.HTTP modeedit
The
http
mode guides you through the process of generating certificates foruse on the HTTP (REST) interface for Elasticsearch. It asks you a number of questions inorder to generate the right set of files for your needs. For example, dependingon your choices, it might generate a zip file that contains a certificateauthority (CA), a certificate signing request (CSR), or certificates and keysfor use in Elasticsearch and Kibana. Each folder in the zip file contains a readme thatexplains how to use the files.Parametersedit

Microsoft office home and student 2007 product key generator. Specifies the password for the generated private keys.
Keys stored in PKCS#12 format are always password protected, however,this password may be blank. If you want to specify a blank passwordwithout a prompt, use
--pass '
(with no =
) on the command line.Keys stored in PEM format are password protected only if the
--pass
parameter is specified. If you do not supply an argument for the--pass
parameter, you are prompted for a password.Encrypted PEM files do not support blank passwords (if you do notwish to password-protect your PEM keys, then do not specify--pass
).--pem

Examplesedit
The following command generates a CA certificate and private key in PKCS#12format:
You are prompted for an output filename and a password. Alternatively, you canspecify the
--out
and --pass
parameters.You can then generate X.509 certificates and private keys by using the newCA. For example:
You are prompted for the CA password and for an output filename and password.Alternatively, you can specify the
--ca-pass
, --out
, and --pass
parameters.By default, this command generates a file called
elastic-certificates.p12
,which you can copy to the relevant configuration directory for each Elasticproduct that you want to configure. For more information, seeSetting up TLS on a cluster.Using elasticsearch-certutil
in Silent Modeedit
To use the silent mode of operation, you must create a YAML file that containsinformation about the instances. It must match the following format:
The name of the instance. This can be a simple string value or can be aDistinguished Name (DN). This is the only required field. |
An optional array of strings that represent IP Addresses for this instance.Both IPv4 and IPv6 values are allowed. The values are added as SubjectAlternative Names. |
An optional array of strings that represent DNS names for this instance.The values are added as Subject Alternative Names. |
The filename to use for this instance. This name is used as the name of thedirectory that contains the instance’s files in the output. It is also used inthe names of the files within the directory. This filename should not have anextension. Note: If the name provided for the instance does not represent avalid filename, then the filename field must be present. |
When your YAML file is ready, you can use the
elasticsearch-certutil
commandto generate certificates or certificate signing requests. Simply use the --in
parameter to specify the location of the file. For example:This command generates a compressed
test1.zip
file. After you decompress theoutput file, there is a directory for each instance that was listed in theinstances.yml
file. Each instance directory contains a single PKCS#12 (.p12
)file, which contains the instance certificate, instance private key, and CAcertificate.You an also use the YAML file to generate certificate signing requests. Forexample:
This command generates a compressed file, which contains a directory for eachinstance. Each instance directory contains a certificate signing request(
*.csr
file) and private key (*.key
file).
