I want to convert my 24 word BIP 39 pass phrase into 4 digit codes. Then encrypt those 4 digits using a cypher.
Does anyone know or recommend any cyphers for encrypting a 4 digit number?

I think a shift cypher would be easiest
Basically you take the alphabet and match a number to it. Then you pick a random number and shift it over all the letters. ![number-substitution-cypher|600x365]
So if you wanted to encode the word
BLUE
The BIP 39 is 139
So we could just add a random number to each digit like 4
so 1 becomes 5
3 becomes 7
9 becomes 4
574 = element (on bip 39)
then to decrypt subtract 4 from each number 574
574
-4
139
Zoo is 2048
so you may want to add the 10th digit
6 4 8 2
