binary to 5-letter words encoder/decoder
Hi all, I recently finished the English word list for my encoder/decoder and thought I would share the program with you. The software allows users with an offline computer and pencil and paper only to use their favorite encryption software and then encode /decode small binary blobs error free*, compared to other solutions IMHO. I must admit that this procedure is a bit time consuming but it should give users at least one more option in their tool set. *I received today an encrypted postcard in QR-code but was not able to decode the message, even with high dpi scan settings. https://github.com/sac001/b2w/ Regards Stefan

i see that list contains the words young and youth. you really want to avoid words in that list that have a close phonetic similarity in case these words are read out over an audio communication channel. there is such word lists already available, you don't have to reinvent the wheel. pgpwords is decades old and does exactly so.
Thanks for your feedback, much appreciated! I am aware of the well known pgp-wordlist, however like you state when using audio channels the pgp-wordlist may not be the best option for non-native (US) English speakers, because it contains many words which probably a lot of non-native speakers are not familiar with and have then difficulties to write the words down. Then there is mnemonicodes available, but the list in there contains to many words, while it is more efficient when encoding. Hence my humble approach.

If you are using zbar, and the data contains 8-bit characters, zbar 0.10 does not decode this correctly. you need to compile zbar from the mercurial sources: https://sourceforge.net/p/zbar/code/ci/default/tree/ `hg clone http://hg.code.sf.net/p/zbar/code zbar-code` to get the content out right. but maybe you are using some other processor than zbar.

Thanks for the info, will try out tomorrow. Regards Stefan
i'm used to zbarcam, which also had the irritating attribute of adding a linebreak after every qr code output, so reading a bunch of binary qr codes would output them interspersed with linebreaks. On Sat, Oct 17, 2020 at 6:11 PM Stefan Claas <spam.trap.mailing.lists@gmail.com> wrote:
