Previously, the volume_key documentation did not specify which of the two block devices to use as an argument to volume_key(8). Due to this problem, unexpected errors caused confusion. With this update, the volume_key.8 man page and the README file clarify whether to use the encrypted or plaintext block device, and how to recognize it. (BZ#636541)

Previously, libvolume_key did not provide textual descriptions for a subset of error conditions. Due to this behavior, some error messages contained nonsensical characters instead of readable text. This update adds the missing textual descriptions. The error messages now describe the cause of the error. (BZ#638732)

Previously, the volume_key(8) utility could not be interrupted when waiting for a password or passphrase input. This update makes the volume_key(8) utility interruptible in such cases, and notifies the user if the entered passphrase is incorrect. (BZ#641111)

Previously, the volume_key(8) utility prompted the user for a passphrase before it validated the supplied certificate file, if any. Due to this behavior, any errors in the file were detected only after the user entered additional information. This update detects and reports such errors immediately, without prompting the user for a passphrase. (BZ#643897)
