Haning problems in signature generation

[Trivedi, Ashish]

Hi,
I am trying to port a ssh deamon for nucleus RTOS.
I am having trouble in calculating signature and I am getting error in
BN_mod_inverse of the crypto lib.
What I have done is rather then reading the keys from file I am updating the
keys reading it from strings and converting them into bytes.
I am updating the p, q, g, pub_key and priv_key members of the structure
DSA.
Can any body help me on this.

Regards,
Ashish
