Cryptography actions

  • Article

Cryptography actions enable you to encrypt and decrypt plain text and text from files providing a key and an encoding format.

The Encrypt text with AES action encrypts a text using the AES algorithm and a user-specified encryption key. You can provide the encryption key directly or through a variable.

To encrypt the text of a file directly, use the Encrypt from file with AES action. This action works similarly to the Encrypt text with AES action but requires a source file instead of a text value.

Screenshot of the Encrypt from file with AES action.

To decrypt a text, use the Decrypt text with AES, and enter the encrypted text and the encryption key previously used to encrypt it. To decrypt and store a text in a file, deploy the Decrypt to file with AES and specify a destination path.

Apart from encryption and decryption, the Cryptography group of actions provides actions to hash values with and without a key. Like the encryption actions, you can hash values from files using the Hash from file and Hash from file with key actions.

Important

Passwords entered in designated fields only work on the machine where they were initially set. This is due to the machine-specific encryption used for direct password inputs. If the flow is opened on a different machine, these passwords will not be valid and will need to be re-entered.

Encrypt text with AES

Encrypt a string with AES, using a key and a specified encoding format.

Input parameters

Argument Optional Accepts Default Value Description
Encoding N/A System default, ASCII, Unicode, Big-endian Unicode, UTF-8 Unicode The encoding of the text to encrypt
Text to encrypt No Text value The text to encrypt
Encryption key No Direct encrypted input or Text value The encryption key to use
Padding N/A None, PKCS7, Zeros, ANSIX923, ISO10126 PKCS7 The padding to use for the selected encryption algorithm
