![]() ![]() #Simpleauthority software#The benefit to rolling your own certificates is that you can issue as many certificates as you like for free, although you do have to factor in potential CA software licensing fees, plus the cost of the server hardware used to run the software. That’s because you can act as your own CA and issue your own digital certificates for internal corporate use. For example, a basic VeriSign SSL certificate valid for one year costs $399, while an Extended Validation certificate which requires more extensive fact checks costs $1499 for one year.īut if your organization runs a secure web server that’s only used by employees, or if you encrypt email sent between employees, or if you use digital certificates to authenticate employees onto the corporate VPN, then there’s really no need to pay a CA for certificates at all. In fact they charge a range of prices for certificates, based on the length of keys that are employed and the amount of effort they put into verifying that the information they are certifying is correct. Then it simply comes down to a matter of trust: Do you trust the reputation of the CA, and therefore do you believe that what the CA certifies to be true really is true?Įstablished CAs such as VeriSign have good reputations, and for that reason they can charge for the certificates they issue. Since every browser has the CA’s public key, it can use that to verify that the certificate really was issued by the CA in question. A certificate issued by a CA states that something is true, and is digitally signed with the CA’s private key. You can also verify someone else’s identity by using their public key to decrypt something that could only have been encrypted with their private key.Ĭertificates are typically issued by Certificate Authorities (CAs), which are trusted third parties whose root certificates (containing their public keys) are bundled in all popular web browsers. If you have someone else’s public key, then you can send them an encrypted message that only they can decrypt with their private key. ![]() Certificates are a vital part of PKI because they provide a means to establish the ownership of an encryption key. #Simpleauthority code#Digital certificates lie at the heart of Public Key Infrastructure (PKI) security technologies such as encrypted email, document signing, VPN access, server SSL authentication, and software code signing. ![]()
