SSL/TLS certificates can be issued in different formats, but the most common formats are:

  1. PEM (Privacy Enhanced Mail) format: PEM is a widely used format for SSL/TLS certificates. PEM certificates are encoded in Base64 and have a file extension of .pem. They are often used on Apache and Nginx web servers.

  2. PKCS#12 format: PKCS#12 (Public-Key Cryptography Standards #12) is a binary format that can be used to store SSL/TLS certificates along with the private key. PKCS#12 certificates have a file extension of .pfx or .p12 and are often used on Windows web servers.

  3. DER (Distinguished Encoding Rules) format: DER is a binary format that is used for SSL/TLS certificates. DER certificates have a file extension of .der and are often used in Java applications.

In addition to these formats, SSL/TLS certificates can also be provided in other formats, such as PFX, JKS, and CER.

The format of an SSL/TLS certificate depends on the requirements of the server or application that will be using the certificate. Many web servers support multiple certificate formats, so it is important to choose the format that is compatible with your server or application.
