libolm3 3.2.10~dfsg-5ubuntu1 (ppc64el binary) in ubuntu jammy

 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.
