Khoorio

Khoorio is a FTP client that allows you to safely encrypt your files with the AES Rijndael cipher before uploading them to a FTP server.
The key used to encrypt the files is derived by a key derivation function (HMAC-SHA1) as follows:
encryptionKey = HMAC-SHA1(hash_plaintext_file,user chosen master password).
With this key the user allows someone to decrypt a specific file, without the need to share his master password to that person. As it consists of a personalized key, the receiving party will only be allowed to decrypt those specific files for which he has received the key, unless he possesses the master password that was used to encrypt the files. Khoorio allows the users to save their encryption keys and FTP credentials securely by the use of Windows Data Protection API (DPAPI) protection.
