Crate tink_hybrid
source ·Expand description
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
).
