Struct matrix_sdk_crypto::olm::SessionKey

source ·
pub struct SessionKey { /* private fields */ }
Expand description

The session key, can be used to create a InboundGroupSession.

Uses the session-sharing format described in the Olm spec.

+—+––+––––+––––+––––+––––+——+———–+ | V | i | R(i,0) | R(i,1) | R(i,2) | R(i,3) | Kpub | Signature | +—+––+––––+––––+––––+––––+——+———–+ 0 1 5 37 69 101 133 165 229 bytes

The version byte, V, is “\x02”. This is followed by the ratchet index, iii, which is encoded as a big-endian 32-bit integer; the 128 bytes of the ratchet; and the public part of the Ed25519 keypair.

The data is then signed using the Ed25519 key, and the 64-byte signature is appended.

Implementations§

source§

impl SessionKey

source

pub fn to_bytes(&self) -> Vec<u8>

Serialize the SessionKey to a byte vector.

source

pub fn from_bytes(bytes: &[u8]) -> Result<SessionKey, SessionKeyDecodeError>

Deserialize the SessionKey from a byte slice.

source

pub fn to_base64(&self) -> String

Serialize the SessionKey to a base64 encoded string.

This method will first use the SessionKey::to_bytes() to convert the session key to a byte vector and then encode the byte vector to a string using unpadded base64 as the encoding.

source

pub fn from_base64(key: &str) -> Result<SessionKey, SessionKeyDecodeError>

Deserialize the SessionKey from base64 encoded string.
