HashFile

This activity enables users to create a unique hash value for an input file. The hash value serves as a digital fingerprint, ensuring the file’s integrity and authenticity. Hashing is particularly useful for checking that a file hasn’t been modified, as even a tiny change in the file’s content will generate a completely different hash value.

Points to note

1. To generate a unique hash value for the provided file, a “Secret” key is required for the following algorithm types: 
a. HMAC using MD5 (Deprecated)
b. HMAC using SHA-1 (Deprecated)
c. HMAC using SHA-256
d. HMAC using SHA-384
e. HMAC using SHA-512
2. There is no minimum character requirement for the “Secret key” for the above algorithm types.
3. The “Secret key” parameter will not appear in the properties section when using any of the above algorithm types. Instead, you will find the option within the activity when you double-click on it.

Properties

INPUT

Algorithm: This parameter indicates to choose the algorithm type from the drop-down menu that is used to generate the hash for the file based on it.

1. HMAC using MD5 (Deprecated)
2. HMAC using SHA-1 (Deprecated)
3. HMAC using SHA-256
4. HMAC using SHA-384
5. HMAC using SHA-512
6. SHA-1
7. SHA-256
8. SHA-384
9. SHA-512

Refer to the documentation below to view the types of algorithms.

By default, the activity recommends the most commonly used type, ” HMAC using SHA-256”.

DelayAfter: It assists the user to add a delay before initiating subsequent activities. The delay duration here is in milliseconds. By default, it is set to “1000” milliseconds.
When the option is left blank, the delay will not be considered.

DelayBefore: It assists the user in adding a delay before starting the execution of the activities. The delay duration here is in milliseconds. By default, it is set to “1000” milliseconds.
When the option is left blank, the delay will not be considered.

Input File Path*:  This parameter indicates the input path of the file for which the hash value needs to be generated.

It accepts values in the “String” datatype. You can either hardcode the values in “String” format or provide a variable in “String” datatype.

Key Encoding: It assists the user to choose the key encoding type from the drop-down menu that is used to perform the encryption algorithm.

Click here to refer the documentation to view the types of key encoding.

By default, the activity recommends the most commonly used type, “Unicode UTF-8”.

MISC

DisplayName: Displays the name of the activity. The activity name can be customized, which aids in troubleshooting.

SkipOnError: Specify the “Boolean” value as “True” or “False.”

True: Continue executing the workflow regardless of any errors thrown.
False: Halt the workflow if it encounters any errors.
None: If the option is left blank, the activity will, by default, behave as if “False” were chosen.

Version: It indicates the version of the feature being used.

OUTPUT

Hash: It assists the user to declare a variable to view the output of the activity as the “HASH” value generated for the provided input file. 

This field returns values in “String” datatype. You can either hardcode the values in “String” format or can provide the variable in “String” datatype.

Result: It provides the ability to view the execution status of the activity. It returns values in “Boolean.”

True: Indicates that the activity has been executed successfully without any errors.
False: Indicates that the activity has been unsuccessful due to an unexpected error being thrown.

* Represents mandatory fields to execute the workflow.
