security - Difference between PGP and SMIME -

-

i wondering why there need 2 secure email standards. if not wrong, nowadays pgp , smime provide more or less same functionality.

in past, difference pgp build on web of trust, whereas smime used third trusted party. in meantime think can configure pgp ca. further, pgp intended encrypt plain mail messages while smime decrypt attachments. in meantime sure pgp can same.

so question is: there difference between these 2 protocols?

many thanks, andrew

openpgp data encryption , signing standard. it's use in securing e-mails called (open)pgp/mime , combination of openpgp , mime. pgp/mime not used nowadays. s/mime on other hand supported mail clients , mail processing applications.

the problem s/mime non-trivial procedure obtain certificates e-mail signing. point of view pgp/mime more handy (at least or occasional uses).

just note: our secureblackbox product offer support of above mentioned technologies, have extensive experience them.
