If you\u2019re here because you\u2019re wondering \u201cwhat is a self signed certificate?\u201d then you\u2019re in luck. Not only can we explain what it is, but we can help you understand the advantages and disadvantages of self signed certificates! <\/p>\n\n\n\n
A self-signed certificate is an SSL certificate not signed by a publicly trusted certificate authority (CA) but by one\u2019s own private key. The certificate is not validated by a third party and is generally used in low-risk internal networks or in the software development phase.<\/p>\n\n\n\n
But, first, a little background\u2026<\/p>\n\n\n\n
A self signed certificate (or \u201cself-signed certificate\u201d for\nall of the punctuation fans who are reading this article) is a digital\ncertificate that\u2019s not signed by a publicly trusted certificate authority (CA).\nThis can include SSL\/TLS certificates, code signing certificates, and S\/MIME\ncertificates. The reason why they\u2019re considered different from traditional\ncertificate-authority signed certificates is that they\u2019re created, issued, and\nsigned by the company or developer who is responsible for the website or\nsoftware being signed. This is why self signed certificates are considered\nunsafe for public-facing websites and applications. <\/p>\n\n\n\n
Most commonly, the term \u201cself signed certificates\u201d refers to self signed SSL certificates, which are also known as private SSL certificates. But as we mentioned earlier, the term also applies to other X.509 digital certificates. <\/p>\n\n\n\n

In order\nto retain trust, all CAs must follow the strict guidelines regarding\nvalidation, issuance, and revocation that are stipulated by the CA\/B\nForum. <\/p>\n\n\n\n However, self signed certificates are not directly monitored\nby the CA\/B Forum. Hence, there are many loopholes a hacker can exploit. For\nexample, self-signed certificates usually have a one-year validity period. But you\ncan’t trust the validity dates of a self-signed certificate because the user can\nalways generate and sign a new certificate containing a valid date range.\nAnother example is the revocation ambiguity. With a CA-issued certificate, the\nCA has the authority to revoke the certificate immediately if it is misused or\nthe private keys are compromised. The revocation procedures of self signed\ncertificates are as complicated as revoking an entire certificate authority! <\/p>\n\n\n\n Let\u2019s take a real-life scenario here. In the U.S., the Department of Motor Vehicles (DMV) tests your driving skills before issuing a driver\u2019s license to you. What if you print a piece of paper on your home printer with a line \u201cI certify that I know how to drive\u201d and self-sign it? You might the best driver ever existed on this planet earth, but would any traffic authority trust your fake driver\u2019s license? No way! <\/p>\n\n\n\n In much the same way, self-signed SSL certificates are\nsigned by the certificate owner rather than a reputable CA. Browsers consider\nonly certificates that are signed by trusted certificate authorities as\ntrustworthy. When your certificate is signed by you, and browsers don\u2019t know\nyou (don\u2019t take it personally), then they won\u2019t trust the certificate. It\u2019s\nreally that simple! <\/p>\n\n\n\n If saving money is the only reason for you to use a\nself-signed certificate, we have good news for you!
