If I used a key string having a different character , the chipher give correct result

cPassword = "dataworld4Asistdbc"
cKeyStr =   "qwertyuopasdfghjkl"

? decrypt(encrypt(cKeyStr, cPassword), cKeyStr) && return  dataworld4Asistdbc [correct]

*** same password different key string

cKeyStr =   "##################" 
? decrypt(encrypt(cKeyStr, cPassword), cKeyStr) && return  {`utnsoc5`tjrugmb [wrong]

>I had tested some string with chipher function. The tested strings and results is following.
