But in the Openssl 9.8k , this function is changed to
#define INIT_DATA_A (unsigned long)0x67452301L
#define INIT_DATA_B (unsigned long)0xefcdab89L
#define INIT_DATA_C (unsigned long)0x98badcfeL
#define INIT_DATA_D (unsigned long)0x10325476L
FIPS_NON_FIPS_MD_Init(MD5)
{
c->A=INIT_DATA_A;
c->B=INIT_DATA_B;
c->C=INIT_DATA_C;
c->D=INIT_DATA_D;
c->Nl=0;
c->Nh=0;
c->num=0;
return 1;
}
I cannot see any MD_Init function there .So how is MD_Init function is
generated ?
Thanks
