LMK is generated by HSM !

As Chung indicates, this is a job for an HSM.

Do you have one or are you 'testing'? If so, do you *need* an LMK, why
not use clear keys in your encryption algorithms?

thanks for your answer chung & mark, I know that LMK is generated using HSM but can jpos framework generate lmk programmatically? I believe that SMAdaptor can do it but i don't know how, did you have experience to generate lmk using SMAdaptor?

I remember one mail , have HSM simulator , try to search this and use HSM simultor written by .net

I would like to understand why you feel you need an LMK? An LMK is used
to keep keys secure, using one outside of an HSM breaks the whole
security, why not just just a test LMK - or *clear* keys?

How about using this one?

as good as any for testing.

In r2773 I just added a new CLI command 'smconsole'.

You can 'svn update', then call

java -jar jpos.jar --cli

There you can type 'man smconsole'.

You want to use something like 'smconsole -lmk /tmp/yourlmk.cfg -rebuildlmk'.
