caesar-saladROT18 Class
The ROT18 Cipher is a monoalphabetic substitution cipher combining ROT13 and ROT5.
Examples using static factory methods:
ROT18.Cipher().crypt('ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789'); // returns: 'NOPQRSTUVWXYZABCDEFGHIJKLM5678901234'
ROT18.Decipher().crypt('NOPQRSTUVWXYZABCDEFGHIJKLM5678901234'); // returns: 'ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789'
Examples using constructors:
new ROT18().crypt('ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789'); // returns: 'NOPQRSTUVWXYZABCDEFGHIJKLM5678901234'
new ROT18().crypt('NOPQRSTUVWXYZABCDEFGHIJKLM5678901234'); // returns: 'ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789'
