The action supports either standard base64 or URL base64 encoding.
| Parameter | Description | | ------------- | ----------------------------------------- | | Text | The text to decode. | | Encoding Type | The type of encoding: `Standard` or `URL` |
## Decode Hex Converts a hex-encoded string to a string. For example: For the hexadecimal encoded string: `626C696E6B`, the returned string will be: `blink`.
| Parameter | Description | | -------------- | ------------------------------------------------------------------- | | Encoded String | The string that needs to be decoded. Bytes are decoded using UTF-8. |
## Decode JWT Decode a JSON Web Token (JWT).
| Parameter | Description | | --------- | ------------------------------------------------------- | | JWT | The complete JSON Web Token (JWT) string to be decoded. |
## Encode Base64 Encodes the input text to base64 and prints the result to the output screen. The action supports either standard base64 or URL base64 encoding.
| Parameter | Description | | ------------- | --------------------------------------------------- | | Text | The text to encode. | | Encoding Type | The type of encoding to decode: `Standard` or `URL` |
## Encode Hex Converts a regular string to its hex representation, encoding each character of the string into hexadecimal format. For example: For input string: `blink`, the returned hexadecimal string will be: `626c696e6b`.
| Parameter | Description | | --------- | --------------------------------------------------------------------------------------------------------------- | | String | The string that will be encoded. First, it encodes the string to bytes (using UTF-8) and then the bytes to hex. |
## Encode JWT Encode JSON Web Token (JWT).
| Parameter | Description | | -------------------- | ------------------------------------------------------------ | | Sub | The subject identifier for whom this token is being created. | | Name | The human-readable name associated with the subject. | | Issued At Time (IAT) | The timestamp when this token was issued. |
## Generate MD5 Hash Generates a MD5 hash from a string or from a file. For example: For input string: `blink`, the returned generated MD5 hash will be: `40652ee9ae143f1c1c830f01a5449ecb`.
| Parameter | Description | | ----------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | Source Type | Select whether to generate the hash from the `String` or from a `File`. | | String | The string from which to generate the MD5 hash. | | File Path | The file from which to generate the MD5 hash. | | Working Directory | The directory where the file is located. The filesystem state is preserved across steps using this directory to ensure that files and changes persist for continuity.

## Generate Password Generates a secret password and stores it in a variable.
| Parameter | Description | | ----------------------- | ------------------------------------------------------------ | | Variable Name | The name of the variable to store the generated password in. | | Password Length | The password length, default 10. | | Include Special Chars | `[!-*]` character set - `!@#$%&*`. | | Include Lowercase Chars | `[a-z]` character set - `abcdedfghijklmnopqrst`. | | Include Uppercase Chars | `[A-Z]` character set - `ABCDEFGHIJKLMNOPQRSTUVWXYZ`. | | Include Digit Chars | `[0-9]` character set - `0123456789`. |
## Generate SHA1 Hash Generates a SHA1 hash from a string or from a file. For example: For input string: `blink`, the returned generated SHA1 hash will be: `dcae3a7a7c14a77ef384f1c5df6e63edc780eba0`.
| Parameter | Description | | ----------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | Source Type | Select whether to generate the hash from the `String` or from a `File`. | | String | The string from which to generate the SHA1 hash. | | File Path | The path of the file from which to generate the SHA1 hash. | | Working Directory | The directory where the file is located. The filesystem state is preserved across steps using this directory to ensure that files and changes persist for continuity.

## Generate SHA256 Hash Generates a SHA256 hash from a string or from a file. For example: For input string: `blink`, the returned generated SHA256 hash will be: `e14a51fded1fb9b43de815d3832da099053b583f1d2c01d0495a70f118df426c`.
| Parameter | Description | | ----------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | Source Type | Select whether to generate the hash from the `String` or from a `File`. | | String | The string from which to generate the SHA256 hash. | | File Path | The path of the file from which to generate the SHA256 hash. | | Working Directory | The directory where the file is located. The filesystem state is preserved across steps using this directory to ensure that files and changes persist for continuity.

## Generate UUID V4 Generates a random version 4 UUID. **Note**: A Version 4 UUID is a universally unique identifier that is generated using random numbers. There is no warranty that the provided UUID is unique. ## Get TLS Certificate Information Retrieves information about the security certificate (TLS/SSL) used by an endpoint for encrypted communication.
| Parameter | Description | | --------- | -------------------------------- | | Hostname | The hostname of the endpoint. | | Port | The port number of the endpoint. |
