Expected output generated by OpenSSL (see below) apart from the case
where both password and salt are either NULL or zero length, as OpenSSL
does not support this. For these test cases we have had to use our own
output as that which is expected. Code to generate test cases is as
follows:
#include <openssl/pkcs12.h>
#include <openssl/evp.h>
#include <string.h>
int Keygen_Uni( const char * test_name, unsigned char *pass, int
passlen, unsigned char *salt,
int saltlen, int id, int iter, int n,
unsigned char *out, const EVP_MD
*md_type )
{
size_t index;
printf( "%s\n", test_name );
int ret = PKCS12_key_gen_uni( pass, passlen, salt, saltlen, id, iter,
n, out, md_type );
if( ret != 1 )
{
printf( "Key generation returned %d\n", ret );
}
else
{
for( index = 0; index < n; ++index )
{
printf( "%02x", out[index] );
}
printf( "\n" );
}
printf( "\n" );
}
int main(void)
{
unsigned char out_buf[48];
unsigned char pass[64];
int pass_len;
unsigned char salt[64];
int salt_len;
/* If ID=1, then the pseudorandom bits being produced are to be used
as key material for performing encryption or decryption.
If ID=2, then the pseudorandom bits being produced are to be
used as an IV (Initial Value) for encryption or decryption.
If ID=3, then the pseudorandom bits being produced are
to be used as an integrity key for MACing.
