ok - first start with 2 very large prime numbers
one of these is kept secret and is called the private key
the other is made public and is called the public key
if i want to send you an email and i want to digitally sign it to prove it came from me i need to add some numbers (doesn't matter what numbers) to the end which i encrypt with my private key
you receive the email and decrypt the extra numbers with my public key
if you get the right numbers at the end then the email came from me - if not then someone has tampered with it

Read through the brochure on Thawte.com's website. They offer free digital certificates to support digital signatures.
