Hebrew scholars made use of simple monoalphabetic substitution ciphers around 500 to 600 BC.
Cryptology is the study of codes and ciphers while cryptography is the creating of codes and ciphers.
Encryption and decryption algorithms are called ciphers in cryptography
The Hebrew people were the first people to use the old testament.
There is no information available on what percentage of people use an electric blanket. Many people choose not to use them because some blankets may be fire hazards. Also, diabetics are warned not to use them.

stream ciphers and block ciphers

Yes Benjamin Franklin invented ciphers and codes
Cryptology is the study of codes and ciphers while cryptography is the creating of codes and ciphers.
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.

Hi, I would say it is more than 120 It is. If my reasoning is correct, there are 360,000 unique ciphers. My reasoning is this: when i/j is counted as one letter and repetition is not allowed (as in Playfair), there are 25*24 = 600 possible digrams. Since each digram corresponds to one of those unique digrams, there are 600^2 = 360,000 unique Playfair ciphers (one should probably actually use 359,999 because one of the "ciphers" maps each digram to itself).
To accurately answer your question, I would need to know the specific options you are referring to. However, generally speaking, a cipher is a method of transforming text to secure its content. Common types include substitution ciphers, transposition ciphers, and block ciphers. If an option does not involve any form of text transformation or encryption, it would likely not be considered a type of cipher.
It"s a social club with a sort of mystic and occult angle off. when you have neat little ciphers like FATAL well, what do you expect?
