randomIV :: IO IV Source

mkIV :: ByteString -> Maybe IV Source

getKey Source

Arguments

:: FilePath	File name where key is stored.
-> IO Key	The actual key.

Get a key from the given text file.

If the file does not exist a random key will be generated and stored in that file.

defaultKeyFile :: String Source

The default key file.

getDefaultKey :: IO Key Source

Simply calls getKey defaultKeyFile.

initKey :: ByteString -> Either String Key Source

Initializes a Key from a random ByteString. It's better to give a ByteString with exactly 64 bytes, but anything with at least 32 bytes will work.

Actual encryption/decryption

encrypt Source

Arguments

:: Key
-> IV
-> ByteString	data
-> ByteString

encryptIO :: Key -> ByteString -> IO ByteString Source

decrypt Source

Arguments

:: Key	key
-> ByteString	data
-> Maybe ByteString
