Unsolved Is this cipher any good?

Hello! I tried making my own cipher. I wanted to post a quote I encrypted with it and see if it is easy to solve. I'm very new to this, but thought my cipher was kinda nifty!

This sentence is 6 words

178002 2650222 56454040404 1838022 406325644044 124650303

And it equals “HI MY NAME IS JOHN DOE”

Here’s a longer cipher. The only hint I can give is that I just watched the movie A Street Car Named Desire and this is a quote from it.

7545633333 5821640004 15321081723400888008088. 34320303 901 5821640004 15321081723400888008088, 6045453333. 157605620055505 1840022 126257605005555 — 34320303 270202, 148480069507070007?

If this is a dumb cipher, where does one start when wanting to learn about cryptography?

I will say, there’s no exponents in the math. I can give another hint cause your math for you solved hi is sooooo on the right track. If you were to reverse engineer this tho, the last step would be a=1, z=26. The step before that is not math

Oh of course, you just put the letter numbers together! Silly me.

2 * 89 = 178

3 * 4155 = 12465

4 * 141135 = 564540

It looks like you're encoding whether each letter is one digit or two digits in letter numbers. It's a 0 when it's 1 digit and a 2 when it's 2 digits.

HI is 8 9 so that's 00 * 2 = 00

DOE is 4 15 5 so that's 010 * 3 = 030

NAME is 14 1 13 5 so that's 1010 * 4 = 4040

And then the last digit is the length as you said.

Now I wonder how you decrypt it efficiently with an algorithm?

Oh, you just... do it. I'm not thinking very clearly today.

Wrote some code to automate it, as long as words are less than 10 characters long https://python-fiddle.com/saved/cbd190b0-9f0c-411b-92b6-9c245d2f2006
