Hi,
PKCS#1 v2.1 document showed the steps needed to implement a MGF1 on the section B.2.1.
I don't think that 'PKCS1_MGF1' function in the rsa_oaep.c was properly implemented.
The step #3 on the section said 'For counter from 0 to \lceil{l / hLen}\rceil-1, do the following...'
But in 'PKCS1_MGF1', they just wrote:
for (i = 0; outlen < len; i++)
{...}
The 'len' variable is mask length, which in the document should be the mask length divided by seed length and then subtract one.
I think the loop should be something like this:
for (i = 0; outlen < len/seedlen - 1; i++)
{...}
I hope my question was clearly expressed here, and I want your help, any help.
