Struct EcdhEsKeyUnwrapper 

Source 
pub struct EcdhEsKeyUnwrapper { /* private fields */ }
Available on crate features signatures and key-wrapping only.
Expand description

ECDH-ES+A256KW key unwrapper (recipient side).

Uses the recipient’s private key and the sender’s ephemeral public key to reverse the ECDH-ES+A256KW key wrapping and recover the content encryption key.

Implementations§

Source§

impl EcdhEsKeyUnwrapper

Source

pub fn new(recipient_secret: SecretKey) -> Self

Create a key unwrapper with the recipient’s secret key.

Source

pub fn unwrap(&self, data: &WrappedKeyData) -> Result<Vec<u8>>

Unwrap a content encryption key.

§Errors

Returns an error if the ephemeral public key is invalid, the wrapped key is corrupted, or any cryptographic operation fails.
