Generate All Keys Using Armstrong Axion Algorithm

Before signing the Contract.jar JAR file containing the contract file, you need to generate keys, if you don't already have suitable keys available. You need to sign your JAR file using your private key, and your recipient needs your corresponding public key to verify your signature.

This lesson assumes that you don't have a key pair yet. You are going to create a keystore named examplestanstore and create an entry with a newly generated public/private key pair (with the public key in a certificate).

Now pretend that you are Stan Smith and that you work in the legal department of Example2 corporation. Type the following in your command window to create a keystore named examplestanstore and to generate keys for Stan Smith:

The keystore tool prompts you for a keystore password, your distinguished-name information, and the key password. Following are the prompts; the bold indicates what you should type.

The preceding keytool command creates the keystore named examplestanstore in the same directory in which the command is executed (assuming that the specified keystore doesn't already exist) and assigns it the entered password. The command generates a public/private key pair for the entity whose distinguished name has a common name of Stan Smith and an organizational unit of Legal.

The self-signed certificate you have just created includes the public key and the distinguished-name information. (A self-signed certificate is one signed by the private key corresponding to the public key in the certificate.) This certificate is valid for 90 days. This is the default validity period if you don't specify a -validity option. The certificate is associated with the private key in a keystore entry referred to by the alias signLegal. The private key is assigned the password that was entered.

Self-signed certificates are useful for developing and testing an application. However, users are warned that the application is signed with an untrusted certificate and asked if they want to run the application. To provide users with more confidence to run your application, use a certificate issued by a recognized certificate authority.

How to Generate a Symmetric Key by Usingthe pktool Command

Some applications require a symmetric key for encryption and decryptionof communications. In this procedure, you create a symmetric key and storeit.

  • If your site has a random number generator, you can use thegenerator to create a random number for the key. This procedure does not useyour site's random number generator.

  • You can instead use the dd command withthe Solaris /dev/urandom device as input. The dd commanddoes not store the key. For the procedure, see How to Generate a Symmetric Key by Using the dd Command.

  1. (Optional) If you plan touse a keystore, create it.

    • To create and initialize a PKCS #11 keystore, see How to Generate a Passphrase by Using the pktool setpin Command.

    • To create and initialize an NSS database, see Example 15–5.

  2. Generate a random number for use as a symmetric key.

    Useone of the following methods.

    • Generate a key and store it in a file.

      The advantageof a file-stored key is that you can extract the key from this file for usein an application's key file, such as the /etc/inet/secret/ipseckeys fileor IPsec.


      keystore

      The value file specifies the file typeof storage location for the key.

      outkey=key-fn

      Is the filename when keystore=file.

      keytype=specific-symmetric-algorithm

      For a symmetric key of any length, the value is generic. For a particular algorithm, specify aes, arcfour, des, or 3des.

      keylen=size-in-bits

      Is the length of the key in bits. The number must be divisibleby 8. Do not specify for des or 3des.

      dir=directory

      Is the directory path to key-fn.By default, directory is the current directory.

      print=n

      Prints the key to the terminal window. By default, the valueof print is n.

    • Generate a key and store it in a PKCS #11 keystore.

      Theadvantage of the PKCS #11 keystore is that you can retrieve the key by itslabel. This method is useful for keys that encrypt and decrypt files. Youmust complete Step 1 beforeusing this method.


      label=key-label

      Is a user-specified label for the key. The key can be retrievedfrom the keystore by its label.

      keytype=specific-symmetric-algorithm

      For a symmetric key of any length, the value is generic. For a particular algorithm, specify aes, arcfour, des, or 3des.

      keylen=size-in-bits

      Is the length of the key in bits. The number must be divisibleby 8. Do not specify for des or 3des.

      token=token

      Is the token name. By default, the token is Sun SoftwarePKCS#11 softtoken.

      sensitive=n

      Specifies the sensitivity of the key. When the value is y, the key cannot be printed by using the print=y argument.By default, the value of sensitive is n.

      extractable=y

      Specifies that the key can be extracted from the keystore.Specify n to prevent the key from being extracted.

      print=n

      Prints the key to the terminal window. By default, the valueof print is n.

    • Generate a key and store it in an NSS keystore.

      Youmust complete Step 1 beforeusing this method.


      keystore

      The value nss specifies the NSS type ofstorage location for the key.

      label=key-label

      Is a user-specified label for the key. The key can be retrievedfrom the keystore by its label.

      keytype=specific-symmetric-algorithm

      For a symmetric key of any length, the value is generic. For a particular algorithm, specify aes, arcfour, des, or 3des.

      keylen=size-in-bits

      Is the length of the key in bits. The number must be divisibleby 8. Do not specify for des or 3des.

      token=token

      Is the token name. By default, the token is the NSS internaltoken.

      dir=directory

      Is the directory path to the NSS database. By default, directory is the current directory.

      prefix=directory

      Is the prefix to the NSS database. The default is no prefix.

      print=n

      Prints the key to the terminal window. By default, the valueof print is n.

  3. (Optional) Verify that the key exists.

    Useone of the following commands, depending on where you stored the key.

    • Verify the key in the key-fn file.


    • Verify the key in the PKCS #11 or the NSS keystore.

Example 14–5 Creating a Symmetric Key by Using the pktool Command
Generate all keys using armstrong axiom algorithm chart

In the following example, a user creates a PKCS #11 keystore for thefirst time, and then generates a large symmetric key for an application. Finally,the user verifies that the key is in the keystore.


Example 14–6 Creating a DES Key by Using the pktool Command

In the following example, a secret key for the DES algorithm is created.The key is stored in a local file for later decryption. The command protectsthe file with 400 permissions. When the key is created,the print=y option displays the generated key in the terminalwindow.

DES mechanisms use a 64-bit key. The user who owns the keyfile retrievesthe key by using the od command.


Example 14–7 Creating a Symmetric Key for IPsec Security Associations

Generate All Keys Using Armstrong Axiom Algorithm For Beginners


In the following example, the administrator manually creates the keyingmaterial for IPsec SAs and stores them in files. Then, the administrator copiesthe keys to the /etc/inet/secret/ipseckeys file and destroysthe original files.

  • First, the administrator creates and displays the keys thatthe IPsec policy requires:


  • Then, the administrator creates the following /etc/inet/secret/ipseckeys file:


  • After verifying that the syntax of the ipseckeys fileis valid, the administrator destroys the original key files.


  • The administrator copies the ipseckeys fileto the communicating system by using the ssh command oranother secure mechanism. On the communicating system, the protections arereversed. The first entry in the ipseckeys file protectsinbound packets, and the second entry protects outbound packets. No keys aregenerated on the communicating system.
