Flexlm ECC alternate patching methods

[nikkapedd]

You need only to change the public key not the private ..
Every time the program check the public key, then authenticate your sign according with the vendor's pubkeys..
But pay attention if the program use also vendor_info or vendor_String certificate to authenticate the license, patching only the pub key is not enough to make a working license...

alekine322, patching only the vendor is not enough to make a working license.. You need to patch also the ECC in the exe/dll files

Beside the patch, we still need get lmcrypt that has private/public key paris that match with the patch. Seems compile SDK with setting s below will create private/public keys that consistent with the patch, so I ask
what's the relationship.

#define LM_SEED1 0x11111111
#define LM_SEED2 0x22222222
#define LM_SEED3 0x33333333
