Certificate Decoder

About Certificate Decoder

A certificate Decoder is used to decode a PEM-encoded SSL certificate and check if it contains the correct information. The certificate decoder tool helps you to understand the contents of a certificate and ensure all information contained inside is correct. The Certificate Decoder uses SSL certificate-encoded data to extract all the information contained in this certificate.

Certificate Decoder

The certificate signing request (CSR) decoder tool decodes information within your CSR so that you can verify it is accurate and up-to-date. The CSR Decoder Tool is a tool that allows you to inspect the certificate signing request code for SSL certificates and view advanced information.

How to Use Certificate Decoder?

CSR decoder (certificate signing request) which will analyze the CSR that is pem-encoded and show its attributes. It decodes PKCS7 bundles of your pem encoded certificates to find out validity dates, key sizes, algorithms, etc. Here is how to use the certificate decoder:

To use the certificate decoder tool, paste your certificate into the field.
Press enter and start the process.
Let the certificate decoder do the rest.
There should always be five dashes on either side of both prompts.

How Does Certificate Decoder work?

Certificate Decoder works in a set of complex mechanisms. All this ensures the result is always accurate. Here is how it works:

Decode any X.509 certificate formatted in PEM by pasting the contents into the text box, then clicking on Decode.
An X.509 certificate includes the cryptographic public key, its owner, the issuer, and a digital signature from the issuer verifying the contents of the certificate.
If the certificate's signature is valid, and the software trusts the issuer, then the cryptographic public key can be used to communicate securely with the subject of the certificate.

Why Use Certificate Decoder?

The certificate context contains, both directly and encrypted, all of the essential information about the certificate. It is a simple tool for an SSL certificate decoder, which can be used by anyone to decode the important data encoded into an SSL certificate such as the webserver name, alternate web server name, valid certificate timeframe, Issuer, Serial Number, etc.

Advantages of Certificate Decoder

The certificate decoder offers many benefits for decoding CSR certificates, creating CSR certificates, checking SSL installations, installing SSL, and much more. Here are the main advantages of using a Certificate Decoder:

Easily determine whether or not your certificates are installed properly on your servers.
Check the information about the certificate which the authority or CA will use to build your certificate.
Check if the information contained in them is accurate.
