Encryption

In cryptography, encryption is the process of encoding information. This process converts the original representation of the information, known as plaintext, into an alternative form known as ciphertext. Ideally, only authorized parties can decipher a ciphertext back to plaintext and access the original information.

Is there any security in scrambling bits? (lemmy.nz)

Like, could you just invert all the bits in a block of data and turn it into nonsense?

Or shift/rotate bits, so 10000101 would become 00001011, rather than using an encryption function.

It would be easy to break if you just figured out which bit operations were made, but it's a wierd thing to do so.. would it be obvious at all that it was such a simple encryption method from the raw data?

Just had that thought, it sounds like a 'security through obscurity' measure.

That would be a transposition cipher on the level of bits instead of characters, so it should have the same properties https://en.wikipedia.org/wiki/Transposition_cipher?wprov=sfla1

transposition cipher

Ohh that's what it's called, thanks!
