Hi,

1. what are these h0....h4 ?

2. How are they generated ?

3. Could you help to locate code in openssl ?

typedef struct SHAstate_st {
     SHA_LONG h0, h1, h2, h3, h4;
     SHA_LONG Nl, Nh;
     SHA_LONG data[SHA_LBLOCK];
     unsigned int num;
} SHA_CTX;

Thanks,,


Read the specification of the SHA-1 algorithm (either in the FIPS 180-1
standard or in a textbook).

Enjoy
