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.
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.
