Comparing two strings that are the same are apperenty NOT the same.

19:19:13 [SEVERE] Cirno32c875860e049e6c77baedad979df804 != Cirno32c875860e049e6c
77baedad979df804

Here's them line by line.
Cirno32c875860e049e6c77baedad979df804
Cirno32c875860e049e6c77baedad979df804

I see no difference. Code I'm using to compare them both.
if(admins.getString("admins." + sender.getName() + "." + arg[1]).equals("Cirno" + EncryptIt(arg[0],arg[1]))){

And here's my custom config file (admins) stuff:

Code:

admins:
  Evangon:
    MD5: Cirno32c875860e049e6c77baedad979df804
    SHA-512: Cirno72356f7e292f3da69832467a30353ee09f038aca8ad5d191a46aa0b93a47fe0d3ebcb19185869cff54408ff40f5d2ab17bc0812853a2f3bc2b8ef285110a8148

P.S: If you really really want to know what the MD5 and SHA-512 decrypted are, it's "LOLHAI".

 

check the lengths. Perhaps there is a space or a null character in the string, that you wouldn't see from a log by itself.

 

08:10:36 [SEVERE] Cirno32c875860e049e6c77baedad979df804(37) != Cirno32c875860e04
9e6c77baedad979df804(37)

Apparently, they match the length.

 

Are you maybe doing == instead of .equal?

 

Ahh missed that xP
well I'm out of idea for it then.

 

Can you post the whole code please? I know it will likely be of no use, but the line you posted is correct.

 

Maybe the two strings have a different encoding?

I am aware that I need to clean this up a bit.

 

You're prepending "Cirno" to the string twice. Your message in the "else" statement is not accounting for the fact that you have this error, thus you haven't found it.

 

What an idiot I am... Thanks.
