Encrypt File

UiPath.Cryptography.Activities.EncryptFile

Description

Encrypts a file with a key based on a specified key encoding and algorithm.

Windows, Cross-platform configuration

File - The file to be encrypted, stored as an IResource variable. Select the Plus menu to switch to the Input Path input.
Algorithm - A drop-down menu which enables you to select the encryption algorithm you want to use. The following options are available: AES (Deprecated), AES GCM, DES (Deprecated), RC2 (Non-FIPS) (Deprecated), Rijndael (Non-FIPS) (Deprecated), and TripleDES.

Options

Key Encoding - The encoding used to interpret the key specified in the Key property. The following options are available: System default, Unicode, Unicode (Big-Endian), Unicode (UTF-32), Unicode (UTF-32 Big-Endian), US-ASCII, Western European (ISO), and Unicode (UTF-8).
Output file name and location - The path where you want to save the encrypted file. This field supports only strings and String variables.

Note: Relative folder paths are recommended to account for the different file structure between Windows and Linux machines when executing a project. A relative path follows the format newFolder/newFileName.enc. The activity creates the target folder if it does not already exist.
Overwrite - If a file already exists, selecting On overwrites it. If the toggle is set to Off, a new file is created. The default value is Off.
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.

Depending on the output path and if the file already exists, the following results can occur:

Output file name and location	Overwrite	Output result
Unset	Off	A file with the original file name + the suffix "_Encrypted". If the file already exists, an error is thrown.
Unset	On	A file with the original file name + the suffix "_Encrypted". If the file already exists, the file will be overwritten.
Set	Off	A file as per user preference. If the file already exists, an error is thrown.
Set	On	A file as per user preference. If the file already exists, the file will be overwritten.

Output

Encrypted File - Reference to the decrypted file retrieved by the activity for use in other activities.

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.
DisplayName - The display name of the activity.

Input

Algorithm - A drop-down menu which enables you to select the encryption algorithm you want to use. The following options are available: AES (Deprecated), AES GCM, DES (Deprecated), RC2 (Non-FIPS) (Deprecated), Rijndael (Non-FIPS) (Deprecated), and TripleDES.
Note:
When using the AES GCM algorithm, the decryption input must be provided in the format of (concatenated bytes): Salt (8bytes) + IV (12 bytes) + encryptedData (variable bytes) + Tag (16 bytes)
The activity also uses the following parameters:
- PBKDF2 iterations count is 10000
- The generated key is 256-bit (32 bytes)
Note that the 256-bit generated key is not the same as the Key input option.
Encrypted Filename - The file name you want to use to save the encrypted file.
Input Path - The path to the file that you want to encrypt. This field supports only strings and String variables.
Key - The key that you want to use to encrypt the specified file. This field supports only strings and String variables.
Key Encoding - The encoding used to interpret the key specified in the Key property. This field supports only Encoding variables.
Key Secure String - The secure string used to encrypt the input file.
Output file name and location - The path where you want to save the encrypted file. This field supports only strings and String variables.
Overwrite - If a file already exists at the path specified in the OutputPath field, selecting this check box overwrites it. If unchecked, a new file is created. By default, this check box is cleared.
