Description:
development files for the olm Double Ratchet implementation
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. . This package contains the development files for compiling programs that use olm.
