the utility of the certificat is to avoid the middle
men attack, so you have a public key(encryption)
certified .
the use of the smime is compulsory if we want to have
a PKCS7 format, for example Signed and envelopped data
.
The PKCS7 is a standard who describes a general syntax
for data that may have cryptographic operation applied
to it as Signed and envelopped data .
I hope that im more clear here .
