Types

data ScrubbedBytes :: *

ScrubbedBytes is a memory chunk which have the properties of:

• Being scrubbed after its goes out of scope.
• A Show instance that doesn't actually show any content
• A Eq instance that is constant time

Instances

Eq ScrubbedBytes

Ord ScrubbedBytes

Show ScrubbedBytes

Monoid ScrubbedBytes

ByteArray ScrubbedBytes

ByteArrayAccess ScrubbedBytes

NFData ScrubbedBytes

data NoiseException

Represents exceptions which can occur. DecryptionFailure is thrown if a symmetric decryption operation fails, which is usually the result of an invalid authentication tag. HandshakeStateFailure is thrown if the HandshakeState is improperly initialized for the given handshake type.

If your goal is to detect an invalid PSK, prologue, etc, you'll want to catch DecryptionFailure.

Constructors

DecryptionFailure String

HandshakeStateFailure String
