HOTP Component

Properties   Methods   Events   Config Settings   Errors  

The HOTP component allows creation of HMAC-Based One-Time passwords.

Syntax

TipaHOTP

Remarks

The HOTP component implements the HOTP algorithm defined in RFC 4226 (HMAC-Based One-Time Password). These types of passwords are commonly used as a second factor of authentication in multi-factor authentication scenarios.

To begin specify the shared secret in the Secret property.

Next, you may set Counter. If this property is not set, the component will use a default value.

To create the password call CreatePassword. The Password property will be populated with the new password.

To validate a password set the Password property and call ValidatePassword. The method will return True or False to indicate success or failure.

PasswordLengthThe length of the generated password.
SecretLengthThe length of secret to generate.
BuildInfoInformation about the product's build.
CodePageThe system code page used for Unicode to Multibyte translations.
LicenseInfoInformation about the current license.

UseFIPSCompliantAPITells the component whether or not to use FIPS certified APIs.
UseInternalSecurityAPITells the component whether or not to use the system security libraries or an internal implementation.

Counter Property (HOTP Component)

The counter used for HMAC-Based One Time Password creation or validation.

Syntax

property Counter: Int64 read get_Counter write set_Counter;

Default Value

0

Remarks

This property holds the counter value used for HMAC-Based One Time Password creation or validation. This value must be specified before calling CreatePassword or ValidatePassword. The value should be incremented each time a password is created.

The default value is 0.

Password Property (HOTP Component)

The HMAC-Based One Time Password.

Syntax

property Password: String read get_Password write set_Password;

Default Value

''

Remarks

This property holds the HMAC-Based One Time Password. This property is populated after calling CreatePassword. This property must be set before calling ValidatePassword.

Secret Property (HOTP Component)

The Base32 encoded shared secret used when creating and validating a password.

Syntax

property Secret: String read get_Secret write set_Secret;

Default Value

''

Remarks

This property specifies the Base32 encoded shared secret used when creating and validating a password. This should be set before calling CreatePassword or ValidatePassword.

If this is not set before calling CreatePassword a random secret will be automatically generated. This functionality provides an easy way to create new secret values. The length of the secret is defined by SecretLength.

Config Method (HOTP Component)

Sets or retrieves a configuration setting.

Syntax

function Config(ConfigurationString: String): String;

Remarks

Config is a generic method available in every component. It is used to set and retrieve configuration settings for the component.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, access to these internal properties is provided through the Config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

CreatePassword Method (HOTP Component)

Creates a HMAC-Based One Time Password.

Syntax

procedure CreatePassword();

Remarks

This method creates a HMAC-Based One Time Password.

The following properties are applicable when calling CreatePassword.

Calling CreatePassword populates the Password property with the created password.

If Secret is not specified before calling this method a random secret will be automatically generated.

Reset Method (HOTP Component)

Reset the variables to default value.

Syntax

procedure Reset();

Remarks

This method will reset the variables to default value.

ValidatePassword Method (HOTP Component)

Validates a HMAC-Based One Time Password.

Syntax

function ValidatePassword(): Boolean;

Remarks

This method validates a HMAC-Based One Time Password.

The following properties are applicable when calling ValidatePassword.

The method will return True if the password is validated, False otherwise.

Error Event (HOTP Component)

Information about errors during data delivery.

Syntax

type TErrorEvent = procedure (
  Sender: TObject;
  ErrorCode: Integer;
  const Description: String
) of Object;

property OnError: TErrorEvent read FOnError write FOnError;

Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the component raises an exception.

ErrorCode contains an error code and Description contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.

Config Settings (HOTP Component)

The component accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, access to these internal properties is provided through the Config method.

HOTP Config Settings

HashAlgorithm:   The hash algorithm used to sign the password.

This setting specifies the hash algorithm used to sign the password. Possible values are:

  • SHA1 (default)
  • SHA256
  • SHA512
PasswordLength:   The length of the generated password.

This setting specifies the length of the generated password. Possible values are:

  • 6 (default)
  • 7
  • 8
SecretLength:   The length of secret to generate.

When Secret is empty and CreatePassword is called a random secret value will be generated. This setting determines the length of the randomly generated secret. The default value is 32.

Base Config Settings

BuildInfo:   Information about the product's build.

When queried, this setting will return a string containing information about the product's build.

CodePage:   The system code page used for Unicode to Multibyte translations.

The default code page is Unicode UTF-8 (65001).

LicenseInfo:   Information about the current license.

When queried, this setting will return a string containing information about the license this instance of a component is using. It will return the following information:

  • Product: The product the license is for.
  • Product Key: The key the license was generated from.
  • License Source: Where the license was found (e.g., RuntimeLicense, License File).
  • License Type: The type of license installed (e.g., Royalty Free, Single Server).
  • Last Valid Build: The last valid build number for which the license will work.
MaskSensitive:   Whether sensitive data is masked in log messages.

In certain circumstances it may be beneficial to mask sensitive data, like passwords, in log messages. Set this to True to mask sensitive data. The default is False.

This setting only works on these components: AS3Receiver, AS3Sender, Atom, Client(3DS), FTP, FTPServer, IMAP, OFTPClient, SSHClient, SCP, Server(3DS), Sexec, SFTP, SFTPServer, SSHServer, TCPClient, TCPServer.

UseFIPSCompliantAPI:   Tells the component whether or not to use FIPS certified APIs.

When set to True, the component will utilize the underlying operating system's certified APIs. Java editions, regardless of OS, utilize Bouncy Castle FIPS, while all the other Windows editions make use of Microsoft security libraries.

FIPS mode can be enabled by setting the UseFIPSCompliantAPI configuration setting to True. This is a static setting which applies to all instances of all components of the toolkit within the process. It is recommended to enable or disable this setting once before the component has been used to establish a connection. Enabling FIPS while an instance of the component is active and connected may result in unexpected behavior.

For more details please see the FIPS 140-2 Compliance article.

Note: This setting is only applicable on Windows.

Note: Enabling FIPS-compliance requires a special license; please contact sales@nsoftware.com for details.

UseInternalSecurityAPI:   Tells the component whether or not to use the system security libraries or an internal implementation.

When set to False, the component will use the system security libraries by default to perform cryptographic functions where applicable.

Setting this setting to True tells the component to use the internal implementation instead of using the system security libraries.

This setting is set to False by default on all platforms.
