securityUtility command

The securityUtility command supports plain text encryption and SSL certificate creation for Liberty.

Documentation for the securityUtility command in version 21.0.0.11 and later is available on the Open Liberty website.

Syntax

The command syntax is as follows:

securityUtility task [options]

Where the options are different based on the value of task.

CAUTION:

Different operating systems and command line environments treat some characters differently. In many environments, you can redefine which characters are special and how they behave.

By default, in the Windows environment, if you have an exclamation point (!) in your input string, it must be escaped by the caret character (^). The following example has a value of a! encoded.

D:\Liberty\images\855\Liberty855\wlp\bin>securityUtility encode "a^!"

For some operating systems, you might need to use single quotation marks around arguments that are passed to the tool.

If you use a terminal emulator, make sure that your session is configured to use the same code page as your server.

Refer to your operating system, command shell, and terminal emulator documentation about special characters and code pages if you experience unexpected results.

Parameters

The following tasks are available for the securityUtility command:

encode

Encodes the provided text by using Base64. If no options are specified, the command enters interactive mode. Otherwise, the provided text is encoded. Text with spaces must be put in quotation marks.

The options are:

--encoding=encoding_type

Specifies how to encode the password. Supported encodings are xor, aes, and hash. If this option is not provided, a default encoding of xor is used. Currently, the aes type uses AES-128 encryption.

Note: You can use the hash encoding option to encode passwords for the basic user registry.

You can also use the option to encode passwords for the quickStartSecurity element.

--key=encryption_key

Specifies the key to be used when you encode by using AES encryption. This string is hashed to produce an encryption key that is used to encrypt and decrypt the password. The key can be provided to the server by defining the variable wlp.password.encryption.key whose value is the key. If this option is not provided, a default key is used.

See also information about setting the variable for wlp.password.encryption.key.

--listCustom

Display the information of the custom password encryption in JavaScript Object Notation (JSON) format. The information consists of:

name: The custom password encryption algorithm name.
featurename: The feature name.
description: The description of the custom password encryption.

For more information about custom password encryption, see Developing a customPasswordEncryption Provider.

--notrim

Specify whether space characters are removed from the beginning and end of the specified text. If this option is specified, the provided text is encoded as it is. If this option is not specified, space characters from the beginning and end of the specified text are removed.

text

The text that is to be encoded.

createSSLCertificate

Creates a default keystore that includes an SSL certificate for use in a server or client configuration.

Keystore details:: location: In the resource/security/key.p12 file of the server or client directory.; type: PKCS12; Through 19.0.0.2: location: In the resource/security/key.jks file of the server or client directory.; Through 19.0.0.2: type: JKS; password: Password that is provided with the --password option. The password is needed to open the keystore file and retrieve the key from the keystore file.
Certificate details:: type: Self-signed certificate.; size: 2048 by default, an alternative size can be specified with the --keySize option.; signature algorithm: SHA256withRSA, can be customized with the--sigAlg option.; validity: 365 days by default, can be customized with the --validity option.; SubjectDN: CN=<hostname>,OU=<client or server name>,O=ibm,C=us by default, can be customized with the --subject option.

The options are:

--server=name: Specifies the name of the Liberty server for which the keystore and certificate is created. This option cannot be used if the --client option is specified.
--client=name: Specifies the name of the Liberty client for which the keystore and certificate is created. This option cannot be used if the --server option is specified.
--keyType=keystore type: Specifies the keystore type to generate. To generate a JKS keystore, specify the --keyType option with the value of JKS. By default, a PKCS12 keystore is generated. However, to explicitly specify the generation of a PKCS12 keystore, specify the --keyType option with the value of PKCS12.
A PKCS12 keystore has a number of advantages over a JKS keystore. The PKCS12 keystore is more extensible, supports stronger cryptographic algorithms, and is widely adopted. The PKCS12 format is frequently the format that certificate authorities provide when they issue certificates.
--keySize=size: Specifies the certificate key bit size. The default value is 2048.
--password=password: Specifies the password to be used in the keystore, which must be at least six characters in length. This option is required.
--passwordEncoding=password_encoding_type: Specifies how to encode the keystore password. Supported encoding value is xor or aes. If this option is not provided, a default value of xor is used.
--passwordkey=password_encryption_key: Specifies the key to use to encode the keystore password by using AES encryption. This string is hashed to produce an encryption key that is used to encrypt and decrypt the password. The key can be provided to the server by defining the variable wlp.password.encryption.key whose value is the key. If this option is not provided, a default key is used.
--validity=days: Specifies the number of days that the certificate is valid, which must be equal to or greater than 365. If this option is not provided, a default value of 365 is used.
--subject=DN: Specifies the Distinguished Name (DN) for the certificate subject and issuer. If this option is not provided, a default value of CN=<hostname>,OU=<server or client name>,O=ibm,C=us is used. The CN value is retrieved by using a java method to get the machine's local hostname. If the hostname cannot be resolved, the IP address is returned.
--sigAlg: Specifies the signature algorithm that is used to sign the self-signed certificate. The signature algorithm that is supported depends on what is supported by the underlying JRE. Stronger signature algorithms might require the JRE to have the unrestricted policy file in place.; The command accepts SHA256withRSA (default), SHA1withRSA, SHA384withRSA, SHA512withRSA, SHA1withECDSA, SHA256withECDSA, SHA384withECDSA, and SHA512withECDSA. The signature algorithms that end with RSA creates certificates with RSA keys and the signature algorithms that end with ECDSA creates certificates with Elliptical Curve (EC) keys.
Note: If you are using certificates that are created with EC keys, then your server needs a customized ciphers list in the ssl configuration to include EC ciphers.
--extInfo: Specifies any X.509 certificate extension information that it uses to create the default certificate. By default, the Subject Alternative Name extension is added to the certificate with the host name of the server. If the --extInfo option is used, the value is passed directly to the keytool command. Use the syntax of the --ext flag on the keytool command.

help

Prints help information for a specified task.

Usage

The following examples demonstrate correct syntax:
