rhubarbcipher (rubygems): RHUBARBCIPHER is a plausibly deniable multi-key file encryption/decryption system for GNU/Linux and BSD that combines one-time pad encryption/decryption with Shamir's Secret Sharing in an attempt to encrypt files in a versatile yet information-theoretically secure manner. RHUBARBCIPHER is only recommended for smaller files (e.g. less than 15000KiB) due to the time taken to encrypt/decrypt data, which increases as a function of file size. It includes an optional decoy feature which allows users to specify a decoy file and generate a set of decoy keys in addition to the real keys. Size similarity between the decoy file and the real file is strictly enforced. WARNING: Please be aware that this gem has not undergone any form of independent security evaluation.
