0.7.0

What's Changed

Features

• Add an Elliptic Curve Integrated Encryption Scheme. This scheme can be used to establish a secure ephemeral encrypted channel, in situations for which Olm may be unsuitable due to complexity or the unavailability of long-term identity keys. There is also support for out-of-band authentication of the receiver side. The scheme was designed primarily for purposes of implementing Matrix QR code login. (#151).

Security

• Use a constant-time Base64 encoder for secret key material to mitigate side-channel attacks leaking secret key material (#156) (Low, CVE-2024-40640, GHSA-j8cm-g7r6-hfpq).
