In many cases you will not need to know whether Revolution uses string numerals or an internal form of the number.
The above test two and three will put numeral strings into the arrays. If you find that the encryption box is more efficient with internal numbers in the array, then put (zap+0) into myList[i]. As you use the numbers and replace them with calculated values, they will become and stay the faster internal form. Unless you do some weird magic, the key is always a numeral.
All results are strings once they get to the message box. The property numberFormat is used to convert. Your numbers are hardly affected. The quote marks will not show up on strings unless you put them in the strings.
Because the Blowfish S-boxes have only 256 entries, you might see if using numToChar(i) as the key gives you any speed advantage. Also, since Blowfish uses 32-bit numbers, you might consider extracting four char sets using a char chunk expression from a string instead of an array and then use binaryEncode/binaryDecode.
