Another similar website for people who like this: https://cryptohack.org/ It is like cryptopals, but in a Catch The Flag format. Many challenges on cryptopals do exist on CryptoHack too, but CryptoHack also have some even harder challenges to solve. - Source: Hacker News / 12 months ago

The point is, you're working with a 200-year old manual cipher method. The field of cryptography has thoroughly perforated it and moved past manual ciphers and machine ciphers and onto mathematical ciphers whose strength is in functions whose inverses are astronomically more difficult to compute than the functions themselves, and key generation schemes that ensure that keys are never repeated no matter how many...
