河豚是一種通用的加密工具是用來保護您最敏感的數據免受未經授權的觀看。您可以使用河豚與其它河豚用戶安全地交換電子郵件，壓縮和加密您的數據文件到拉鏈式聚氨酯泡沫檔案，使用隱藏在圖像文件的像素數據的隱秘，并分發非河豚用戶自解密檔案。廣泛的抹選項也可永久刪除敏感數據。

Puffer is a general purpose encryption utility that is used to protect your most sensitive data from unauthorized viewing. You can use Puffer to securely exchange email with other Puffer users, compress and encrypt your data files into zip-style PUF archives, use steganography to hide data among the pixels of image files, and distribute self-decrypting archives to non-Puffer users. Extensive wiping options are also available to permanently erase sensitive data.
