Hi all,
 
  I am finding a strange problem with
HMAC_Init_ex.  After the call to this function the stack is getting corrupted.  
  The sequence of functions used are-  
   HMAC_CTX ctx ;    HMAC_CTX_init(&ctx);   HMAC_Init_ex(&ctx, 
hash_key->v, hash_key->l, EVP_sha1(), NULL);  
  Key->v points to 20 bytes of memory, while key->l is 20.  
  Are there some necessary pre-requisites to this?  
  Can anyone help?  
  Thanks,
  Prashant
