# ElGamal Control

Encrypt and decrypt data with the ElGamal asymmetric key encryption algorithm for public-key cryptography.

## Syntax

**ElGamal**

## Remarks

The ElGamal control is used to encrypt/decrypt data with the ElGamal asymmetric key encryption algorithm for public-key cryptography.

To begin, you must either specify an existing key or create a new key. Existing public or private keys may be specified by setting Key. To create a new key pair, call [CreateKey](#createkey-method-elgamal-control).

After specifying a key, specify the data you wish to encrypt or decrypt. Call the [Encrypt](#encrypt-method-elgamal-control) or [Decrypt](#decrypt-method-elgamal-control) method to perform the operation.

**Input and Output Properties**

The control will determine the source and destination of the input and output based on which properties are set.

The order in which the input properties are checked is as follows:

- [InputFile](#inputfile-property-elgamal-control)
- [InputMessage](#inputmessage-property-elgamal-control)

When a valid source is found, the search stops. The order in which the output properties are checked is as follows:

- [OutputFile](#outputfile-property-elgamal-control)
- [OutputMessage](#outputmessage-property-elgamal-control): The output data is written to this property if no other destination is specified.

An ElGamal key is made up of a number of individual parameters.

The public key consists of the following parameters:

- [KeyP](#keyp-property-elgamal-control)
- [KeyG](#keyg-property-elgamal-control)
- [KeyY](#keyy-property-elgamal-control)

The control also includes the [KeyPublicKey](#keypublickey-property-elgamal-control) property which holds the PEM formatted public key for ease of use. This is helpful if you are in control of both signature creation and verification process. When sending the public key to a recipient, note that not all implementations will support using the PEM formatted value in [KeyPublicKey](#keypublickey-property-elgamal-control), in which case the individual parameters must be sent.

The private key consists of the following parameters:

- [KeyP](#keyp-property-elgamal-control)
- [KeyG](#keyg-property-elgamal-control)
- [KeyY](#keyy-property-elgamal-control)
- [KeyX](#keyx-property-elgamal-control)

 The control also includes the [KeyPrivateKey](#keyprivatekey-property-elgamal-control) property which holds the PEM formatted private key for ease of use. This is helpful for storing the private key more easily.

## Data Type

Boolean

# Config Method ([ElGamal](#elgamal-control) Control)

Sets or retrieves a configuration setting.

## Syntax

```text
elgamalcontrol.Config ConfigurationString
```

## Remarks

Config is a generic method available in every control. It is used to set and retrieve [configuration settings](#config-settings-elgamal-control) for the control.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the control, 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](#config-settings-elgamal-control), you must call *Config("PROPERTY")*. The value will be returned as a string.

# CreateKey Method ([ElGamal](#elgamal-control) Control)

Creates a new key.

## Syntax

```text
elgamalcontrol.CreateKey
```

## Remarks

This method creates a new public and private key.

When calling CreateKey the Key property is populated with a new private and public key.

An ElGamal key is made up of a number of individual parameters.

The public key consists of the following parameters:

- [KeyP](#keyp-property-elgamal-control)
- [KeyG](#keyg-property-elgamal-control)
- [KeyY](#keyy-property-elgamal-control)

The control also includes the [KeyPublicKey](#keypublickey-property-elgamal-control) property which holds the PEM formatted public key for ease of use. This is helpful if you are in control of both signature creation and verification process. When sending the public key to a recipient, note that not all implementations will support using the PEM formatted value in [KeyPublicKey](#keypublickey-property-elgamal-control), in which case the individual parameters must be sent.

The private key consists of the following parameters:

- [KeyP](#keyp-property-elgamal-control)
- [KeyG](#keyg-property-elgamal-control)
- [KeyY](#keyy-property-elgamal-control)
- [KeyX](#keyx-property-elgamal-control)

 The control also includes the [KeyPrivateKey](#keyprivatekey-property-elgamal-control) property which holds the PEM formatted private key for ease of use. This is helpful for storing the private key more easily.

# Decrypt Method ([ElGamal](#elgamal-control) Control)

Decrypts the input data using the specified private key.

## Syntax

```text
elgamalcontrol.Decrypt
```

## Remarks

This method decrypts the input data using the private key specified in Key. Alternatively, a certificate may be specified by setting Certificate.

**Input and Output Properties**

The control will determine the source and destination of the input and output based on which properties are set.

The order in which the input properties are checked is as follows:

- [InputFile](#inputfile-property-elgamal-control)
- [InputMessage](#inputmessage-property-elgamal-control)

When a valid source is found, the search stops. The order in which the output properties are checked is as follows:

- [OutputFile](#outputfile-property-elgamal-control)
- [OutputMessage](#outputmessage-property-elgamal-control): The output data is written to this property if no other destination is specified.

**Key Size and the Maximum Length of Data**

RSA has an upper limit to the amount of data that can be encrypted or decrypted, also known as message length. This can typically be calculated as the size of the key minus the size of the RSA header and padding.

When not using OAEP, the following formula and table can be referenced. (RSA Key Bytes) - (Header Bytes) = Length of data, where Header Bytes is always 11.

| RSA Key Length (bits) | Length (bits) | Length (bytes) |
| --- | --- | --- |
| 1024 | 936 | 117 |
| 2048 | 1960 | 245 |
| 3072 | 2984 | 373 |
| 4096 | 4008 | 501 |

When using OAEP, the following formula and table can be referenced. (RSA Key Bytes) - (2 * Hash Length Bytes) - 2 = Length of data. The table below assumes SHA-256 for the hash, so Hash Length Bytes is 32.

| RSA Key Length (bits) | Length (bits) | Length (bytes) |
| --- | --- | --- |
| 1024 | 496 | 62 |
| 2048 | 1520 | 190 |
| 3072 | 2544 | 318 |
| 4096 | 3568 | 446 |

# Encrypt Method ([ElGamal](#elgamal-control) Control)

## Syntax

```text
elgamalcontrol.Encrypt
```

## Remarks

This method encrypts the input data using the public key specified in RecipientKey. Alternatively, a certificate may be specified by setting RecipientCert.

**Input and Output Properties**

The control will determine the source and destination of the input and output based on which properties are set.

The order in which the input properties are checked is as follows:

- [InputFile](#inputfile-property-elgamal-control)
- [InputMessage](#inputmessage-property-elgamal-control)

When a valid source is found, the search stops. The order in which the output properties are checked is as follows:

- [OutputFile](#outputfile-property-elgamal-control)
- [OutputMessage](#outputmessage-property-elgamal-control): The output data is written to this property if no other destination is specified.

The *ErrorCode* parameter contains an error code, and the *Description* parameter contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the [Error Codes](#trappable-errors-elgamal-control) section.

# Config Settings ([ElGamal](#elgamal-control) Control)

**MaskSensitiveData**: 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 *True*.

**UseInternalSecurityAPI**: Whether or not to use the system security libraries or an internal implementation. When set to *False*, the control will use the system security libraries by default to perform cryptographic functions where applicable.

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

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