I think it would actually likely be harder, since modern ciphers like RIJNDAEL are designed in such ways to make their output look like a random data, I once saw an analogy, that if you want to have a random number generator as a programmer, you can use a stream cypher and push zeroes to it, which could yield bytes of a homogenous random distribution. So in other words, the binary path from encrypted text to the original is a set of modifications long like the original data, so in other words, it would be like trying to guess a key big like a file, which is unimaginable using brute force. This is one of the reasons I'm in such a deep love with mathematics, the way it protects blockchains for example. Human laws and principles, including those regarding finances, are just words, they apply only as long as the authorities are willing to stick with them, which can break any time and even if it does not, various individuals always find ways around to push through malicious intentions. Blockchain, on the other hand, as long as there are enough people on board, is impenetrable, you can bribe, cheat, seize, deceive, sue, force, intimidate people, institutions, or even countries, but mathematics doesn't care.
