The Discussion:
We talked a bit about video streaming, for example to provide a live screen capture or a prepared presentation. RTTM has done this using a combination of Open Broadcaster Software (OBS) and VDO.ninja (VDO). James mentioned the lanonly option for testing and security purposes.
RJ shared about the upcoming SEMCO meeting and topics to be covered.
RTTM said he was very impressed by ReadEra which is a very handy app for reading ebooks and pdf files. It can provide a very nice display with your choice of font, style and colors. In addition, it can read the text aloud in any of the selected voices. It’s even possible to create a “book on tape” in the mp3 format of a text file.
Carl did a quick demo of the steghide utility which can easily hide a file within an mp4 file using steganography. The steghide command uses an “embedfile”, a “coverfile” and a password to create a “stegofile”. Here is an example of how to embed and then later extract a text file from an mp4 fie.
- steghide embed -ef message.txt -cf cutevideo.mp4
- steghide extract -sf cutevideo.mp4
The Presentation:
Pat gave a very good presentation about the current state of passkeys. The slide show is available here.
Passkeys can be very secure, but they can also be frustrating. Since there are many implementations of passkeys and currently there are no common standards, it may be worthwhile to investigate each service’s features before creating passkeys. For example, a service may or may not have a way to recreate a deleted key or to share a single passkey among several devices.
