Inputs for signature creation

Hi everyone

The following is the mime structure for the message I am intending to sign. This was created using Netscape Messenger (Linux Version). I had this problem before itself. I did get a response from Blake as to what exactly goes into the creation of the digest.

But it did not work out.

Content-Type: multipart/signed;

protocol="application/x-pkcs7-signature";

micalg=sha1;

boundary="------------msB5251B9DF33FAB0FDE461808"

--------------msB5251B9DF33FAB0FDE461808

Content-Type: text/plain; charset=us-ascii

Content-Transfer-Encoding: 7bit

Hello World

--------------msB5251B9DF33FAB0FDE461808

The input to the digest function in my application is:

Content-Type: text/plain; charset=us-ascii

Content-Transfer-Encoding: 7bit

Hello World

The first byte to go into digest function is

Content-Type: text/plain; charset=us-ascii

and thelast byte going into the digest creation function is 'Hello World'. But the output I am getting and the messenger output are totally different I used the ASN Dump to get netscape's digest. This has tied up my work. It would be of great help if somebody could help me with what exactly goes into the digest function.

John and Blake, sorry for the mail to your personal mail account. This has tied up my work and I could not proceed without this.

Thank you very much for your time. Looking for an early response.

cheers

Frank
