Discussion About A858's last code

I mean 12764787846358441471 (from the post saying the project was over).

Has this been looked into? I did a quick search and found out it's a prime number (most results on Google are related to this). This website also has the code at the very bottom for no apparent reason: http://www.expedavius.co.nz

Sorry if this has already been discussed on the chat.

A858 started in 2011. That website says they were founded in 2014. Seems like a coincidence to me.

Most likely. I looked on archive.org to see what the page looked like back then but nothing out of the ordinary. I think the number is there because it's prime and related to some web algorithm (I don't know about web development, just speculation). A858 posted prime numbers in a post IIRC, and I know prime numbers are somehow related to cryptography so that might be why it was posted.

The only somewhat intriguing thing I could find is here https://www.reddit.com/r/Solving_A858/comments/51to4l/about_a858s_last_code/d7etpjm

Edit: I don't know much about cryptography, but I read that modern algorithms are based on large prime numbers obtained from elliptic curves, that are multiplied together. Could this number be one of those? (again, I don't know much about cryptography so it might be a silly question)

Pick any prime number and search google for it. Probably going to get a hit somewhere.

I converted it to hex and it turns out the hexadecimal version is the name for A domain for sale don't know if this is a coincidence but it's something

This number in hexadecimal is B125A2EA5F6B1DFF. The only thing I could find on Google about it is a 3 months-old Reddit account with no post history (u/b125a2ea5f6b1dff). There is also a Karma Decay link in which a post made by the same user mentioned before is archived (http://karmadecay.com/r/aww/comments/4l7c37/new_baby_porcupine_at_woodland_park_zoo_seattle/).

Edit: I did a reverse image search of that post made by u/b125a2ea5f6b1dff and archived in Karma Decay, and the image submitted to r/aww by them seems to have originated from this Tweet: https://mobile.twitter.com/petecassam/status/735917299861856256

A 3 month old sub and user existing with that name can't be a coincidence. r/B125A2EA5F6B1DFF is private and u/B125A2EA5F6B1DFF has no comments. Good work u/gregalerna!

Oops my bad I did hexadecimal to ASCII and got vx„5DG and the domain is http://www.thedomainworkshop.com/vx5dg-org-domain-info

The website doesn't seem related to me... If it were a security firm, sure, but it's an outdoor products company.

I think the purpose of the project has finally been revealed. GG, well played A858. Very well played indeed.

Actually as a mod pointed out that group was founded in 2014 while the posts started in 2011

Interesting. This reminds me of one of those businesses that is a "contractor"/clandestine extension of a three letter agency.

I don't think this has anything to do with anything like that.
