I built a hardware-bound local password vault hidden in a photo
- ptaffs 17d agoI recently learned Steganography, as correctly named in the article, is not the same as Stenography.
- noman-land 17d agoYes, similar to how an apple and a pineapple are not the same.
- nom 17d agoi bet they stuff the data into a PNG chunk next to the image data, so they aren't even doing steganography

- sejje 17d agoI like this idea. What's your security/cryptography background?
- jqpabc123 17d agoSteganography is sort of an art. But standardized and verified digital encryption routines are available in modern operating systems to make strong cryptography experience available and accessible to the average developer.
- sejje 17d agoWhy is that a reply to my comment?
- jqpabc123 17d agoYou asked about cryptography experience. I was atempting to point out that you don't necessarily need crypto experience to implement strong cryptography. The part that really demands experience has already been done and is readily available.
- pshirshov 17d agoNo. Sort of maths. One is not supposed to trust "art" with their passwords.
- jqpabc123 17d ago"Art" as in there are different implementations but none (that I am aware of) that are standardized, proven secure and readily available as a local service. Therefore, the skill of the implementor (aka "art") is likely to factor prominently into the resultant security.
- aleken 17d agoAI webpage?
- throwuxiytayq 17d agoIt's just called "a webpage" now.
- jmuguy 17d agoThis seems like the end result of one of those "chatgpt - make me a business" online courses. There's no information about who's behind it, AI generated content everywhere, etc.
- jqpabc123 17d agoI built something similar years ago to use for a password vault --- data hidden locally in plain sight. Instead of steganography, I simply appended the encrypted data/payload to the end of a JPG file in my photo library. The file opens and displays normally. Part of the photo/carrier file is used as salt for decryption. The part that is used changes randomly based on the last modification time/attribute of the file. The file creation time (displayed in a normal directory list) is maintained/doesn't change with payload modifications. Encryption is also tied to disk parameters so a simple file copy makes the data unreadable. The access utility can be used to move the file and re-encrypt the data on a different disk. A labeled section of the payload data/vault holds TOTP keys so the access utility can also function as a 2FA authenticator.
- nik282000 17d agoSloppy slop. A strong password and strong encryption is enough. The presence of 'blindlock' on a device is a clear indication that one of your files is a wallet. Phoning home to do a licence check is EVERY time you use it is obnoxious and defeats the purpose of having local software.

- poppafuze 17d agono source code == no security.
- normalaccess 17d agoI think I'll ask Codex to make an open source version
- mpalmer 17d agoThe question is, have you done something so unique and challenging that your website itself wouldn't serve as a prompt to rebuild the whole thing? Would I spend less than $49 doing so?

- pshirshov 17d ago> password vault I see "pricing" but can't spot "source code", perhaps you forgot to add a link?
