This in SHA-512, which is irreversible so even if we wanted to attempt it we couldn't.

1. You don't know that
2. the point of this cipher isn't to be solvable, it will make sense in a while

I will not give you decoins for making unsolvable ciphers

1) I don't know that but the Analyze hash tool guesses that.
2) You only get DeCoins for getting ciphers solved anyway so

This in SHA-512, which is irreversible so even if we wanted to attempt it we couldn't.

*Almost irreversible

Technically it is possible to brute-force SHA-512, but it either takes millions of years or a quantum computer more powerful than any that has ever been made (but IBM does think it's possible, so…)

Ok, so we've established that it's SHA256 and cannot be reasonably decoded. Can we please move on?

The real problem is not how long it takes, but that you will have to sort through all of these possibilities. There will be many, many valid English sentences. In fact, there are probably an infinite number of them that map to the same code.

Description: There's an image in here somewhere. (Or, well, an image URL but close enough)
Difficulty: 2
Note: Kind of a rushed cipher, so sorry if it's extremely easy.
Hint: Each symbol finds its mirror, as if gazing backward along the alphabet's spine.

Solution:

https://upload.wikimedia.org/wikipedia/commons/thumb/9/9e/Natalie_shrugging.jpg/389px-Natalie_shrugging.jpg

Method: Brute-forced words with the same characters in the same spots, and googled parts of the URL, before figuring out it was wikimedia commons and then manually converting each encoded character to it's original, with the knowledge of “wikimedia.org” and “wikipedia” being in parts of the URL.
The cipher is a simple letter substitution cipher, numbers and punctuation/special symbols are not changed.
Here's my work: (use monospaced font (should be the default in code block))

But probably only a handful of messages will make sense within the context they're given.

Depends on if you know how long the original string is what that length is. But still, you'd have to sort out all of the messages without any valid words in it, and even then you'd have quintillions of strings left to check for valid sentences (assuming the original string was around 25 characters long)

1. We're assuming you have millions of years on hand anyways, if we're assuming you can brute-force SHA-512- time to invalidate strings is trivial by comparison
2. That's one of the uses of AI.

@50_scratch_tabs, point taken. After this I'll start responding to posts about this on people's profiles.

yeah because no one is going to solve the sha-512 nonsense I give you no shot of adding it until there is a publicly available way of solving it
