            Consists of the following values:

            • A descriptive name

            • An Amazon S3 or Amazon Elastic File System (Amazon EFS) location for the source file to decrypt.

            • An S3 or Amazon EFS location for the destination of the file decryption.

            • A flag that indicates whether to overwrite an existing file of the same name. The default is FALSE.

            • The type of encryption that’s used. Currently, only PGP encryption is supported.

            • Name (string) –

              The name of the step, used as an identifier.

            • Type (string) –

              The type of encryption used. Currently, this value must be PGP.

            • SourceFileLocation (string) –

              Specifies which file to use as input to the workflow step: either the output from the previous step, or the originally uploaded file for the workflow.

              Specifies the location for the file being decrypted. Use ${Transfer:UserName} or ${Transfer:UploadDate} in this field to parametrize the destination prefix by username or uploaded date.

              • Set the value of DestinationFileLocation to ${Transfer:UserName} to decrypt uploaded files to an Amazon S3 bucket that is prefixed with the name of the Transfer Family user that uploaded the file.

              • Set the value of DestinationFileLocation to ${Transfer:UploadDate} to decrypt uploaded files to an Amazon S3 bucket that is prefixed with the date of the upload.

              Note

              The system resolves UploadDate to a date format of YYYY-MM-DD, based on the date the file is uploaded in UTC.
