// Package hybrid provides implementations of the Hybrid Encryption primitive.
//
// The functionality of Hybrid Encryption is represented as a pair of
// 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).
