Using hotmail/yahoo, how can I verify e-mail (using pdf as attachment) was signed and verified?, can I use hotmail/yahoo/google mail for that purpose?

I thought immediately of enigmail http://enigmail.mozdev.org/home/index.php
It allows you to encrypt/sign email using the mozilla email clients, which can send/receive mail from your yahoo, gmail, hotmail.
Your title mentions SSL (openssl), but that's another sort of thing. It's for creating secure connections (to your email server or any other), not for sending encrypted email or digital signing.
Also, both the sender and receiver will have to be signing/encrypting, otherwise it's pointless. -
If you have PGP or GPG you can verify cryptographical ly any string of data if the user has signed or encrypted it with your public key.
I've used enigmail, but I dont like it as much as a desktop solution like PGP or GPG. For some reason I don't trust having a 3rd party doing my encryption and signing for me.Comment
