Geremia's HMAC and SHA1 functions

Timbi (7)
I don't know how to use the function with class

 
 
HMAC(HashAlgorithm *hashAlgo, uint8_t *k, uint32_t kl);


I tried I guess any combination and it still getting red strike.

 
 
HMAC hmac( ? , (unsigned char*)key, strlen(p1));

I tried
1
2
3
4
 
SHA1 sha1;
HMAC hmac( sha1 , (unsigned char*)key, strlen(p1));
or
HMAC hmac( SHA1, (unsigned char*)key, strlen(p1));

Nothing work.

The functions:
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21
22
23

The class HMAC expects a pointer to a class of type HashAlgorithm, a pointer to an uint8_t and a var of type uint32_t kl.

Try the following:
1
2
3
4
 
SHA1 sha1;
uint8_t buf[1024];

HMAC hmac(&sha1, buf, sizeof(buf));

Thanks, strange that I didn't tried with & :)
