Update on Korean Ciphers

I have been wondering how Hangul script can be enciphered. While mentioning some possibilities in "Substitution Cipher for Hangul", I have not seen historical instances. Then, Torbjörn Andersson from Sweden, who saw my first blogpost, told me of actual examples, in which a straighforward solution of separately representing consonants and vowels forming Hangul characters was actually used. This first clue allowed me to do some search and I now uploaded a new article, Korean Cryptography.
