SSL & TLS Certificates Facts:

  1. SSL/TLS certificates provide encryption, authentication, and integrity for online communication, protecting users’ sensitive information, such as passwords and credit card details.
  2. SSL/TLS certificates use public key cryptography to secure data transmission. The certificate contains a public key that is used to encrypt the data, and a private key that is used to decrypt the data.
  3. SSL/TLS certificates can be issued by certificate authorities (CAs) or self-signed. CAs are trusted third parties that verify the identity of the certificate holder and issue certificates accordingly.
  4. There are three types of SSL/TLS certificates: domain-validated (DV), organization-validated (OV), and extended-validation (EV). EV certificates provide the highest level of validation and are used by banks and financial institutions.

SSL & TLS Certificates Benefits:

  1. SSL/TLS certificates protect users’ sensitive information, such as passwords, credit card details, and personal information.
  2. SSL/TLS certificates increase trust and credibility with customers, improving their confidence in the website and the business.
  3. SSL/TLS certificates improve search engine rankings, as Google and other search engines give preference to websites with SSL/TLS encryption.
  4. SSL/TLS certificates help prevent phishing attacks and malware infections, which can harm users and damage the reputation of the website and the business.

SSL & TLS Certificates Trends:

  1. The use of SSL/TLS encryption is becoming more widespread, with more websites and web applications adopting SSL/TLS certificates.
  2. The validity period of SSL/TLS certificates is increasing, with some certificate authorities now offering certificates with a validity period of up to 5 years.
  3. The adoption of EV certificates is increasing, with more banks and financial institutions using EV certificates to provide a higher level of validation and security.

SSL & TLS Certificates Adoption:

  1. The adoption of SSL/TLS certificates is highest in North America, where 98.8% of websites use SSL/TLS encryption, according to Netcraft.
  2. The adoption of SSL/TLS encryption is lower in Asia, where only 89.8% of websites use SSL/TLS encryption, according to Netcraft.
  3. The adoption of SSL/TLS encryption is highest in the financial services industry, where SSL/TLS certificates are used to provide secure online banking and payment services.

The Basics of SSL and TLS Certificates

  1. SSL was first released in 1995, while TLS was introduced in 1999 as a successor to SSL.
  2. SSL and TLS certificates use public-key encryption to secure data transmission over the internet.
  3. SSL and TLS certificates provide three levels of validation: domain validation, organization validation, and extended validation.
  4. SSL and TLS certificates use symmetric encryption to secure the data being transmitted between the server and client.
  5. SSL and TLS certificates are typically issued by a certificate authority (CA), which verifies the identity of the certificate holder.
