Hebrew scholars made use of simple monoalphabetic substitution ciphers around 500 to 600 BC.
stream ciphers and block ciphers
The main weakness of monoalphabetic ciphers is that although the letters themselves change, their frequency does not. So, any enthusiastic cryptographer could crack the code using frequency analysis tables of the original plaintext language

Yes Benjamin Franklin invented ciphers and codes
Cryptology is the study of codes and ciphers while cryptography is the creating of codes and ciphers.
Twofish, Advanced Encryption Standard, Blowfish, Serpent, CAST 5, RC4, TDES, and IDEA are all examples of symmetric encryption methods. In short, any algorithm that uses the same or similar cryptographic keys for encryption and decryption is a symmetric encryption method. Symmetric encryption methods are also divided into two different categories, stream ciphers and block ciphers. These two encryption methods are much like the difference between an interpreter and a compiler in programming. Stream encrypts individual bytes one at a time, while Block encrypts volumes as a whole.
Substitution and transposition.

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.
it depends which stream it is because they are all different sizes.
Encryption and decryption algorithms are called ciphers in cryptography
