NAME

    Passwd::Keyring::OSXKeychain - Password storage implementation based on
    OSX/Keychain.

VERSION

    Version 0.1005

WARNING

    I do not have Mac. I wrote the library mimicking actions of some python
    libraries and tested using mocks, but help of somebody able to test it
    on true Mac is really needed.

SYNOPSIS

    OSXKeychain Keyring based implementation of Keyring. Provide secure
    storage for passwords and similar sensitive data.

        use Passwd::Keyring::OSXKeychain;
    
        my $keyring = Passwd::Keyring::OSXKeychain->new(
             app=>"blahblah scraper",
             group=>"Johnny web scrapers",
        );
    
        my $username = "John";  # or get from .ini, or from .argv...
    
        my $password = $keyring->get_password($username, "blahblah.com");
        unless( $password ) {
            $password = <somehow interactively prompt for password>;
    
            # securely save password for future use
            $keyring->set_password($username, $password, "blahblah.com");
        }
    
        login_somewhere_using($username, $password);
        if( password_was_wrong ) {
            $keyring->clear_password($username, "blahblah.com");
        }

    Note: see Passwd::Keyring::Auto::KeyringAPI for detailed comments on
    keyring method semantics (this document is installed with
    Passwd::Keyring::Auto package).

SUBROUTINES/METHODS

 new(app=>'app name', group=>'passwords folder')

    Initializes the processing. Croaks if osxkeychain keyring does not seem
    to be available.

    Handled named parameters:

    - app - symbolic application name (not used at the moment, but can be
    used in future as comment and in prompts, so set sensibly)

    - group - name for the password group (will be visible in seahorse so
    can be used by end user to manage passwords, different group means
    different password set, a few apps may share the same group if they
    need to use the same passwords set)

    (OSXKeychain-specific)

    - security_prog - location of security program (/usr/bin/security by
    default, possibility to overwrite is mostly needed for testing)

    - keychain - keychain to use (if not default)

 set_password(username, password, realm)

    Sets (stores) password identified by given realm for given user

 get_password($user_name, $realm)

    Reads previously stored password for given user in given app. If such
    password can not be found, returns undef.

 clear_password($user_name, $realm)

    Removes given password (if present)

    Returns how many passwords actually were removed

 is_persistent

    Returns info, whether this keyring actually saves passwords
    persistently.

    (true in this case)
