Matrix project contribution reports: libQuotient end-to-end encryption

Name: Alexey Andreyev

e-mail: yetanotherandreyev@gmail.com

matrix: @aa13q:matrix.org

Idea: "Adding end-to-end encryption to more clients"

Mentors: Alexey Rusakov, Hubert Chathi

Weekly plan

• Update the epic at the github repo
• Implement OneTimeKeysManager with qtolm
• * Implement qt5keychain based olm pickle saving
• Implement creating and registering one-time keys
• Implement configuring a room to use encryption
• Handle incoming events (m.room.encryption, m.room.encrypted, m.room_key events)
• Downloading the device list for users in the room

History

• 1st bonding week: (6/05 - 12/05) formed manuals list, dived into the documentation. Formed a task to research libqtolm possible integration
• 2nd bonding week: (13/05 - 19/05) worked on a side task: "User color coding", added PRs to the Quotient library and the Quaternion client.
• 3rd bonding week: (20/05 - 26/05) trying libqtolm integration options: found qt5.10 qrandomgenerator usage

Coding officially begins

• 1st week: (27/05 - 2/06): added initial Qt<5.10 support to qtolm, integrated qtolm to quotient
• 2nd week: (03/06 - 09/06) started working at issue quotient-im#87 "Upload device public keys". Saved for later (as TODO) a task of saving olm account pickle via qt5keychain.
• 3rd week: (10/06 - 16/06) working on "Upload one-time keys task", OneTimeKeysManager class.
