// Package hybrid provides subtle implementations of the HKDF and EC primitives.
//
// The functionality of Hybrid Encryption is represented as a pair of
// primitives (interfaces):
//
//  * HybridEncrypt for encryption of data
//
//  * HybridDecrypt for decryption of data
//
// Implementations of these interfaces are secure against adaptive chosen
// ciphertext attacks. In addition to plaintext the encryption takes an extra
// parameter contextInfo, which usually is public data implicit from the
// context, but should be bound to the resulting ciphertext, i.e. the
// ciphertext allows for checking the integrity of contextInfo (but there are
// no guarantees wrt. the secrecy or authenticity of contextInfo).
