base64 encryption explained - photographs posted directly on the blockchain

in #base645 years ago (edited)

As you probably know, the SteemIt stores the images on AWS cloud servers. This is different from the texts (post content), which are stored in block-chain (e.g. lots of peer-to-peer nodes storing duplicate and immutable) contents.

You may find a recent post of mine a little concerning. Perhaps HIVE and STEEM witnesses should be. What the post contains is a base64 encryption of a photograph. The encrypted image resides on the blockchain. A copy will be on every HIVE witness server as we speak.

How was such a images encrypted?

Allow me to explain how it would be done under Linux, although it is able to be done on all Windoze boxes as well.

Coverting binary image to base64 and writing results to output.txt:

Let's take as an example an images of an anaconda. The following command will create the base64 encryption of the photograph and place it in the text file output.txt.

$base64 anaconda_PNG15.png > output.txt

Decoding the contents of output.txt and printing it to an image format:

$base64 -d output.txt > anaconda_PNG15_2.png

You will want to know the file extension of the encrypted photograph. In the example photograph in my post you will need to use the extension png.

There will be a 100 STEEM token reward for the first user to post the decrypted photograph from my post to the comments of this post, below.

Happy decrypting!

It seems you can't even give STEEM away these days. 😎

Yes indeed, so it would seem lol. I am afraid such technical endeavors ((my definition of such ranges from tying my shoelaces to placing one foot before the other!!!)) are way beyond my simple mind.

Kudos to you for doing your part to make the platform interesting and foster a little engagement and fun, it does not go un-noticed although at times it may feel fruitless...

Take great care and enjoy that uncharacteristically beautiful UK sun we are being treated to right now, it is far too scarce a commodity to be taken for granted lol :)

Thanks for your input! It must have felt a bit the same on the Titanic after the lifeboats had launched. 🥺

I have no idea what any of this means. I paint with oil paints.

It is a means to put pictures of your painting on the blockchain, as opposed to a centralized AWS cloud servers, in base64 encrypted format just like the text of posts are saved. It would make your images as immutable and the same longevity as the blockchain itself.

I’m here for the 100 Steem giveaway .... where that at ? I don’t understand any of this ... what ?

That's why the prize was so big. 😎

A user on HIVE won on the mirror post there.

Everybody wants Steem. Since the News about Shopify.

Hmmm... had been putting out sell orders for 2500 satoshi waiting for the weekly spikes but maybe it would be good to hold off for a bit to see where the price goes. Thanks for the tip.

Well... the News has been out for a while on this. Maybe it’s what is holding it at .20 while Hive drops day after day ? Not sure what to do anymore

Both HIVE and STEEM have proved to me to both be a failure in terms of governance. Have been trading HIVE for XMR through @blocktrades and recently started selling STEEM on the 2500 satoshi spikes on poloniex. Feeling real bullish on XMR. Will probably leave my HIVE and STEEM accounts at minnow status and milk high paying content creators using the autovote dapps; just dropping round to trade off the powered down tokens.

My feeling is that the next workable DPoS chain will come out of the OpenOrchard team which is basically the old steemit devs.

I am Looking forward to getting my $7,000 Blurt coins and hoping my $ 117,000 Smoke tokens are worth something some day... ha ha .... very happy with my Bitcoins.

I have been sending Steem to Poloniex to buy Bitcoin and Ethereum on the dips. Even bought some Dogecoin in my new Atomic Wallet.

Yeah a lot of the Crypto Tea Leaf readers seem to be hyped on ETH. Had no idea that Minds is using ETH to broker their tokens until my listening to that OpenOrchard interview linked in the comment earlier in this thread.

Oh yeah... I need to check in on my Minds blog.... I had a lot there
