I just got off of Netscapes home page and they have announced Netscape Navigator 2.0. It will include full e-mail funtionality with S/MIME implemented. Does anybody know anything about the S/MIME Protocol? How secure is it?
You can find some documents about s/mime on RSA's web site: http://www.rsa.com/ftpdir/pub/S-MIME/ S/MIME is basicly a mime body enveloped in a PKCS7 message. You can find out more about PKCS from: http://www.rsa.com/ftpdir/pub/pkcs The implementation guide recommends using rc2-cbc 40-bit for content encryption when there is no way to determine the capabilities of the recipient. When you do know what the recipient can do, it recommends using RC2-CBC with a longer key or DES-CBC. For key encryption support for RSA with key sizes of 512 to 1024 is required, and support for 2048 bit keys is recommended. A minimum key size of 768 bits is recommended for US users.
