The Puffer encrypted archive is a specialized data container associated with the Puffer security software originally developed by Briggs Softworks. This format is primarily used for compressing and encrypting individual files or directories into protected backups for secure local storage or transmission. While now regarded as a legacy standard in favor of more modern cryptographic protocols, these archives contain static data and present no inherent execution risks to the host operating system.
