What is a CSR Checker

A CSR Checker is a tool that decodes a CSR so that you can view and verify its contents. Our CSR Decoder provides additional functionality including:

  • CSR signature verification,
  • Key size check,
  • MD5 and SHA1 fingerprints.
CSRs can also be viewed using OpenSSL. To decode a CSR using OpenSSL use the following command:

openssl req -in server.csr -noout -text
