This Thread is nice, i studied this course in my last year in the university we used to decipher our text manually, Caesar cipher is the first encryption code that the humanity knew.
the encryption has improved noticeably in the past decade, thee is some encryption method once created it cannot be decoded, the most significant improvement in the decoding history was the world war two.
Fact: encrypting any text requires a key (so far we have been translating languages which was considered in early ages as a form of encryption).
Another form of cryptography is called hashing. such technique uses an irreversible cipher (md5 is an example but it's too weak nowadays), hashing a string or a text means you will not be able to decrypt it, you can only match it with another value.
