     Creates a signer with the specified identity name.  
     Parameters:  
     `name` \- the identity name.  
     * #### Signer  
     public Signer([String](../../java/lang/String.html "class in java.lang") name,  
           [IdentityScope](../../java/security/IdentityScope.html "class in java.security") scope)  
            throws [KeyManagementException](../../java/security/KeyManagementException.html "class in java.security")

    Throws:  
    `[InvalidParameterException](../../java/security/InvalidParameterException.html "class in java.security")` \- if the key pair is not properly initialized.
