Sevacre's homemade encryption method

i was bored so i decided to make an encryption method

basically its simple, you take two words or sentences or whatever, one is the 'key' and the other is whatever the fuck you want, for this example i will use:
dicks for the key
cocks for the word

you transfer the key into the numerical value of the word, so dicks = 4,9,3,11,19

then you take only the ones digit and combine it all together, so
dicks now equals 4, 9, 3, 1, 9 or 49319

then you take the word cocks and turn it into its numerical value, putting a random symbol/letter/anything other than a number inbetween them.

so cocks becomes
3 A 15 B 3 E 11 C 19
or
3A15B3E11C19

its already a weird jumble of letters and numbers isn't it? now what you do is you multiply the numbers going off of the key's numbers in order

so 3 from the word is multiplied by 4 from the key
15 from the word is multiplied by 9 from the key
the second 3 from the word is multiplied by the 3 from the key
so on and so forth
so the end result becomes

12 A 134 B 9 E 11 C 171
or
12A134B9E11C171

basically a big jumble of letters and numbers that mean nothin unless you know the password/key, and even less if you don't know how to decrypt them.

a few rules:

if a letter in the key, becomes a number that ends with 0 (J and T), you simply substitute those with the number 6 and 8 respectively.

if you run out letters in the key, but still have letters in the word, you just loop the key again, so if i uesd dicks on a 6 letter word, the last letter would be multiplied by the d again.

to unencrypt letters, you divide the numbers obviously, so for our example above

 4    9    3    1    9
 |    |    |    |    |
12 A 134 B 9 E 11 C 171

divide it like that, then you get the original numerical value, to which then you just turn those into letters again.

you cannot send numbers or symbols this way, i'd presume. i made it in like 5 minutes don't judge, just send your numbers in letters like "two" instead of "2" okay?
