Abstract
Concepts and technologies are described herein for sharing encrypted data with enhanced security. In some configurations, an encryption key is generated from a password by the use of a password-based key generation technology. In addition, input data is encrypted using the encryption key. The encrypted data and the generated key may be then shared with a remote computer, such as a server. The encrypted data can then be decrypted at the remote computer by the use of the key. By the use of the technologies described herein, the contents of an encrypted file may be accessed at a remote computer without requiring a user to share the actual password.
