Crate tink_hybrid

Implementations of the HybridEncrypt and HybridDecrypt 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 context_info (but there are no guarantees wrt. the secrecy or authenticity of context_info).

Modules

• subtle
  This module provides subtle implementations of hybrid encryption primitives.

Structs

• EciesAeadHkdfDemHelper
  Generator for tink_core::Aead or tink_core::DeterministicAead primitives for the specified tink_proto::KeyTemplate and key material. in order to implement the subtle::EciesAeadHkdfDemHelper interface.
