libolm3 - 3.2.11~dfsg-1~bpo11+1pureos1 main

Olm is an implementation of the Double Ratchet cryptographic ratchet
described by https://whispersystems.org/docs/specifications/doubleratchet/,
written in C and C++11 and exposed as a C API.
.
This library also includes an implementation
of the Megolm cryptographic ratchet
which is intended for encrypted messaging applications
where there may be a large number of recipients of each message,
thus precluding the use of peer-to-peer encryption systems such as Olm.
.
Megolm is the end-to-end encryption system
for the Matrix communications protocol.
