Show HN: Hide Messages in Images with Steganography

Actually a really cool way of storing passwords in plain sight.

EDIT: Though if you were really secure, you shouldn't be typing your passwords into a third party website in plaintext. Alas, I'll have to write my own.

Nice. I implemented it in Ruby once https://github.com/yankov/steganograph

I'm a bit drunk, so uh, yeah.

LSB steganography is trivially easy to detect. Do not use LSB steganography.

Steganography can be provably secure, with the correct amounts of plain text and "cover data".

Here's one PDF. (http://www.cs.cmu.edu/~biglou/PSS.pdf)

Some people need this kind of stuff to work to avoid torture or other serious consequences, but most implementations are toys to demonstrate proof of concept or to play with the ideas.

tl:dr a real cryptographer will be along to correct my mistakes and provide sensible links.

Being a EE, I bought the Nov'72 issue at one of the Printer's Row Book Fairs, guy asked only about $3 for it, probably didn't know the significance.

Never learned the back stories of other famous images that may be older than "Lenna", e.g. "Girl" and "Cameraman".
