Re: Public Key Extraction in Implicit Certificates (ECQV)

Hi Peter,

The results of the tests with dummy_hash function == 0:

I'll try runnign hundreds of tests, tomorrow; I have done different tests in
the past, though with not a dummy hash function ==0. I don't have access to
any other EC lib right now; I'll have a look at openssl...

The strange thing is that Certicom supposedly states that implements exactly
their SECG articles; and now it seems that somehow they restrict the usage
of their libs to Certicom issued points, in some strange way...

Kindly,

Manuel
