GenerateECKeyPair - Generates a new eliptical curve key-pair using curve25519 as the underlying cryptographic function.

GenerateSharedSecret - Generates a shared secret based on the supplied public/private curve25519 eliptical curve keys.

NewAES returns a new AEAD based cipher object based on the passed in secret and salt.

SaltLength is the length that the passed in salt slice should be for AES objects.

AES represents an aes-256-gcm AEAD cipher object.
