public class certCreation

extends java.lang.Object

This class allows for additional handling of certificates and public/private keys. This functionality refers to storing and retrieving of certificates and public/private keys from the file system. This class has a number of static methods in order to save and to retrieve these objects from files. It also also has a main method that is invoked as a stand-alone program in order to create certificate files.

Method Detail

main

public static void main(java.lang.String[] args)

This method is invoked when running this class as a stand alone program. A typical usage pattern is:

        java moses.security.certCreation CApubkf CAprivkf SUBpubkf CERTf ATTRIBUTES
        

The command line arguments are as follows:

• CApubkf represents the file containing the certifying authority's public key;
• CAprivkf represents the file containing the certifying authority's private key; the key is required for signing the certificate;
• SUBpubkf represents the file containing the public key of the subject;
• CERTf represents the name of the file to hold the certificate to be created;
• ATTRIBUTES represents the attributes embedded in the certificate; if special characters (like ',','(',')') are to be used, they should be accompanied by escape characters specific to the shell/platform.

As a result of running this class, a certificate file is created in the current directory.

putCert

public static void putCert(moses.security.LGICert cert,
                           java.lang.String certFile)

This method saves the provided certificate into a file.

Parameters:

cert - represents the certificate to be saved.

certFile - represents the target file name to save the certificate.

getCert

public static moses.security.LGICert getCert(java.lang.String certFile)

This method reads a previously saved certificate from its file.

Parameters:

certFile - represents the name of the file that contains a certificate.

Returns:

returns the LGI certificate from the file, or null if any exception occurs.

getPublicKey

public static java.security.PublicKey getPublicKey(java.lang.String pubKeyFile)

This method reads a previously saved public key from its file.

Parameters:

pubKeyFile - represents the name of the file that contains the public key.

Returns:

returns the public key from the file.

getPrivateKey

public static java.security.PrivateKey getPrivateKey(java.lang.String priKeyFile)

This method reads a previously saved private key from its file.

Parameters:

priKeyFile - represents the name of the file that contains the private key.

Returns:

returns the private key from the file.
