# PGP Sign File

> PGP Sign File activity for creating a PGP binary signature of a file using a private key.

`UiPath.Cryptography.Activities.PgpSignFile`

## Description

Creates a PGP binary signature of a file using a private key. The signed output contains the original data and the signature. To verify it later, use the [PGP Verify](https://docs.uipath.com/activities/other/latest/developer/pgp-verify) activity with the **Signed File (Binary)** verification type.

This activity produces a binary OpenPGP signature. For a text-friendly armored signature that embeds the plaintext, use the [PGP ClearSign File](https://docs.uipath.com/activities/other/latest/developer/pgp-clear-sign-file) activity instead.

## Project compatibility

**Windows** | **Cross-platform**

## Windows, Cross-platform configuration

* **Input File Path** - The path to the file that you want to sign. This field supports only strings and `String` variables. To use a project resource instead of a path, select the field's input menu and switch to the **Input File** input (an `IResource`).
* **Private Key File Path** - The path to your PGP private key file, used to sign the data. This field supports only strings and `String` variables. To use a project resource instead of a path, select the field's input menu and switch to the **Private Key File** input (an `IResource`).
* **Output File Path** - The full path where the signed file is saved. This field supports only strings and `String` variables.
* **Passphrase** - The passphrase that unlocks the private key. To provide it as a secure string instead of plain text, select the field's input menu and switch to the **Passphrase (Secure)** input (a `SecureString`).

### Advanced options

#### Options
* **Overwrite** - If a file already exists at the output path, this overwrites it. This field only supports Boolean values (`True`, `False`). The default value is `False`.
* **Continue On Error** - Specifies if the automation should continue even when the activity throws an error. This field only supports Boolean values (`True`, `False`). The default value is `False`. As a result, if the field is blank and an error is thrown, the execution of the project stops. If the value is set to `True`, the execution of the project continues regardless of any error.
  :::note
  If this activity is included in **Try Catch** and the value of the **Continue On Error** property is `True`, no error is caught when the project is executed.

#### Output
* **Signed File** - A resource handle to the signed file that was written, stored in an `ILocalResource` variable for use in other activities. The signed bytes are also written to the **Output File Path**.
