What Is an SHA-256 Certificate?
SHA-256 certificates are digital certs that use the SHA-256 hashing algorithm to secure and verify the authenticity of data.

Why Is SHA-256 Irreversible?
SHA-256 is irreversible because it uses a one-way function to generate the hash value, making it difficult to reverse-engineer the input data.

How to Decrypt SHA-256?
SHA-256 encryption is irreversible, meaning that it cannot be decrypted.

What Is an SHA-256 Fingerprint?
The SHA-256 fingerprint is a unique digital representation of data that is generated by the SHA-256 algorithm.

What Is a Shared SSL Certificate?
A shared SSL certificate secures multiple websites on the same server and IP address. It doesn’t belong to the client but to hosting providers or content delivery networks that offer SSL encryption to their customers without requiring each client to purchase or configure their own certificate.

What Is a Self-Signed SSL Certificate?
A self-signed SSL certificate can be issued by anyone rather than a trusted third-party Certificate Authority. While these certificates provide encryption, web browsers don’t trust them and display a warning to the users. Self-signed certs are not suitable for live production.

How to Tell if a Site Has an SSL Certificate?
You can tell if a site has an SSL cert by looking at the URL in the browser’s address bar. If the URL starts with “https://” instead of “http://” and a padlock icon is next to the URL, then the site is using a valid certificate.

What Is the Cost of an SSL Certificate?
The SSL certificate cost varies depending on the validation type and the certificate authority (CA) that issues it. Generally, prices range from a few dollars for entry-level DV certificates to hundreds or even thousands per year for more advanced SSL options.

What Is the Difference Between SSL and TLS Certificates?
SSL (Secure Sockets Layer) and TLS (Transport Layer Security) are cryptographic protocols that establish a secure and encrypted connection between a web server and a client. TLS is an improved version of SSL and the standard protocol today. Due to security vulnerabilities, SSL is no longer supported.
