This looks like transposition cipher again. So I tried Caesar and Vigenere Cipher. But not them. Because I don't know how it was encrypted, I just replaced letters that I know.
For the reason of convenience, the unchanged letters are indicated as upper case, and changed will be lower case.
J -> p
h -> a
l -> s
Result : DC, GDCs Cs a sCRCSaN CKQa GZ SQWQS GUZ. GDCs GCRQ QaYD SQGGQN Cs assCOMQK a spQYCACQK NQSaGCZMsDCp UCGD aMZGDQN SQGGQN. pass: CDaWQANCQMKs
As I can see Cs twice in the result, I'll treat C as i.
C -> i
Result : Di, GDis is a siRiSaN iKQa GZ SQWQS GUZ. GDis GiRQ QaYD SQGGQN is assiOMQK a spQYiAiQK NQSaGiZMsDip UiGD aMZGDQN SQGGQN. pass: iDaWQANiQMKs
Maybe Di is Hi. Therefore GDis will be Ghis, and Ghis looks like this.
D -> h
G -> t
Result : hi, this is a siRiSaN iKQa tZ SQWQS tUZ. this tiRQ QaYh SQttQN is assiOMQK a spQYiAiQK NQSatiZMship Uith aMZthQN SQttQN. pass: ihaWQANiQMKs
I think it works! After a few more like this, there is an answer.
