Yes Benjamin Franklin invented ciphers and codes

Cryptology is the study of codes and ciphers while cryptography is the creating of codes and ciphers.

Some easy code languages include null codes, ciphers, and visual codes. Null codes involve putting unused, or "null" letters in with used letters, ciphers involve switching symbols in for letters, and visual codes involve using real symbols, such as the tip of a hat, as signs for something.

Codes aren't breakable or unbreakable, ciphers are.

To compare cryptography and cryptology we must understand that they are about coding and ciphers. To contrast them, we must understand that cryptography involves the creation of codes and ciphers while cryptology is the study of them.
