We owe so much to people like your mother, I am sure you are very proud of her, as you should be. ❤

"get the key words and back engineer the transmissions and then you have it in clear. " The problem is - all modern cryptograpic systems of the last 200 years try to make this back engineering as hard as possible. Even if you know a plain text word of the encrypted message and even you know the exact position of that word in the encrypted text (which you normally not know) that does not mean that there is an easy way to calculate the used key / setting of the machine.. Not all mathematical operations could be performed in "both directions" with the same effort. For example: Multiplying two prime number which each of them consists of 100 digits is relatively easy as it takes only about 10000 operation steps to do that. But the opposite direction - having the result of this multiplication and trying to find the two prime numbers (and thee are two possible) which when multiplied leading to this result is very hard and takes about 10000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 operations. Or related to Engima - you dont know which rotor setting was used for encryption and even if you know that the clear text for "QNPK" is "HELLO" does not mean that you can easily calculcate the rotor setting which causes HELLO to be encrypted to QNPK and as long as you not found that rotor setting you still can not decyrpt the message. "Any language contains basics like yes and no that is six letters you already have decoded " No - just knowing that an encypted message contains "yes" or "no" does not mean that you have already decoded this parts of the message. "Basic proof reading and understanding the word flow and syntax. " Knowing the syntax of a language does not help at all to encrypt Enigma messages. "and yes current flow to the rotors was an issue but current has pathways it follows and they are predictable" The problem ist that are a lot of possible path ways - for the 3 rotor Enigma for example 158.962.555.217.826.360.000 different possible pathways and without identifing "flaws" in the design the only prediction you can make is that one of this 158.962.555.217.826.360.000 possible settings will decrypt the message. So the only "issue" is to find this single setting 🙂 Following your logic it also should be easy to decrypt modern cryptographic systems like AES - as long as you can guess a key word in the message correctly. In reality there is no known method to do that in a reasonable time even using high performance computers And believe it or not - there are even cryptographic codes which are mathematical proven unbreakable when used correct.

The plugboard is just another rotor which is not rotating but its wiring could be easily changed. The trick is that letters which are not plugged are connected to themself while two letters which were connected by a plug cable where swapped.
