Provide competitive .NET Core implementation #1
So I stumbled over your repository and the original challenge from Trustpilot. I really like your approach to the challenge!
I'll let you discover the performance difference yourself :)
* Avoid the use of Streams on the hot path of the Main mehtod and allow the re-use of a single plaintext buffer * Avoid the encoding of every decrypted ciphertext by searching for the ASCII values of "trust" in the plaintext buffer * Only encode the plaintext buffer, once a possible solution was found
