Thread: Process to make keygen when FlexLM protected software with extra check item

  1. #1

    Thumbs up Process to make keygen when FlexLM protected software with extra check item

    If software protected with FlexLM, and has extra check item such as VENDOR_STRING, when get the Algorithm of VENDOR_STRING, how to call FlexLM SDK to generate the final keygen?

    As alternative, we can get the VENDOR_STRING, and put it into the license sample file, then use lmcrypt.exe to get the final license, here just want to to know the regular process to make the keygen to get the license directly with VENDOR_STRING message. Thanks.

    Process to make keygen when FlexLM protected software with extra check item

    Hi

    Can you explain to be done and to find additional data protection as those shown in these examples:

    FEATURE XXX piedra 9.000 permanent uncounted 07657B6E8B80 \
    VENDOR_STRING="USER" HOSTID=ANY \
    ISSUER="USER" ISSUED=26-Dec-2009 \
    NOTICE="TEAM_X" SN=P-00993

    --------------------------------------------------------------
    SERVER You_PC mac_adress 744
    VENDOR daemon_vendor
    USE_SERVER
    #
    INCREMENT FEATURE1 daemon_vendor Version 05-dec-2011 1 \
    VENDOR_STRING=USER \

    NOTICE="CREATED_BY=licencemanager,UKCAMSNAVISION,UKCAMSNavision_Licence_Generator,fxWin32 \

    CAFC 8DA8 1761 10F3 4F93 19D3 F495"

    These data, such as Find them? or from being generated?
    For each Feature, data changes

    CHKSUM=A17IUN"
    ck=190
    SN=3706475
    SIGN2="1DAA BAC5 1E24 4BC0 EF7B 2D91 BDD6 CC30 29C0 05C6 C0BC \

    CAFC 8DA8 1761 10F3 4F93 19D3 F495"

    Hopefully they can help

    you need to known the way for generating CHKSUM data, all other is flexlm based string, imho.
    this string:

    "CREATED_BY=licencemanager,UKCAMSNAVISION,UKCAMSNavision_Licence_Generator,fxWin32 5.2.0,118 CHKSUM=A17IUN"

    used by NOTICE.
    he also flexlm part.

    Hi, @FoxB

    question: Where I can find a tutorial for Known the way for next Generating data:

    chksum
    ck
    NOTICE
    SIGN2 (I know this is generated when the lmcrypt.exe think. I've created, but always gives me 12 digits, even when I put the information in lm_code.h and lm_code2.h, defined(ENCRYPTION_SEED3), for LM_STRENGTH_239BIT, to give me, length = 120 chars.
    a step I'm doing wrong, but not which

    in advance, thanks for the help

    ck, NOTICE, SIGN2 generated by flexlm sdk. part of source you can got from v9.2 flexlm(imho, source on exetools ftp). regarding CHKSUM - you need to research your target software.
