I have a ABB AC500 PLC and project files writed with CoDeSys V2.3
when I open the project with CoDeSys, a pop-up windows shows for asking input a password. (wow)

this is the codesys library file
http://depositfiles.com/files/8c9pr0r30

Is there some tools can unpassword the file ?
or somebody who could help me to get the password?

Thanks all . (tyou)

NO pop-up window show for inputing password,

The following libraries could not be loaded.
heroctol.lib*2.9.10 14:31:16
. . . . . . . | OK|
-----------------------------------------------------------

It is possible to unpassword, but... the popup dialog asking not for a password. It asking for a KEY.
This library was saved as an external encrypted library.

So this is not just "black box". As a result - library can't be added to project without entering that key.
I guess you see the error window because of that.
I need some time to research the encryption/decryption logic OR...

if CoDeSys really prompt for a PASSWORD (not for a KEY) - send me whole project, the library key must be stored somewhere in there...

I have totally knew the encrypt algorithm which is used to generate the " CoDeSys Internal Library File (*.lib)"
but... (no)
only from encrypted *.lib file, I could find out only a little information and couldn't decrypt it.
still for help!! (tyou)

At the moment I can only say the follow information about heroctrol.lib:
1. The library has no password protection inside.
2. User key is greater or equal 5 characters.

I feel on pictures below referring to the same data block:

heroctrol.lib:

not encrypted library:

Check the difference in columns: when data block contains same data (00) after encryption it looks like series where low bits keeps same and high bits changing. E.g., for column #2: C9 F9 E9 99 89. For identical data block you may also see next row is very similar to previous. The data almost repeats each 16 bytes... so, cryptographic key length = 16 bytes.
If it is possible to define repeatability per each row and if there are simple byte operation is used (e.g. key-byte XOR file-byte) - the chance to decrypt file is quite big..

Thanks, Linkinx64!

You are right. It's a KEY, not password.

I have solved this problem and opened my user library files,

Thanks all, again!

your lib file is very simple,
only read password, no write password, no usergroup passwords (level 0-7)
especially no key!

search this forum with keywords "Bechoff keygen"
you can also get the correct password in 1 second!

it always could crack the read/write password,
but for some lib file with two kinds of passwords at same time,
it will fail to crack group passwords.

if you have the problem, please upload the files and I can help

Hy all.

I have library coded with CodeSys 2.2 with password, and I have a Beckhoff KEY V2.1, which can not be opened.
If you have a version V2.4 or greater, would you send me a link where I can download , please?

Lib: http://www.filedropper.com/showdownload.php/atmobaseqr

PS: I have a version 2.4 but does not resolve. If anyone has any idea how to open the library , please write to me
