+## Guide to Revoking Certificates
+
+In the following steps, we explore how to revoke a X.509 certificate under a CA and obtain a Certificate Revocation List (CRL) for a CA using the Infisical UI.
+
+<Steps>
+  <Step title="Revoking a Certificate">
+    Assuming that you've issued a certificate under a CA, you can revoke it by
+    selecting the **Revoke Certificate** option for it and specifying the reason
+    for revocation. Image 1 Image 2

+
+  </Step>
+  <Step title="Obtaining a CRL">
+    In order to check the revocation status of a certificate, you can check it
+    against the CRL of a CA by selecting the **View CRL** option under the
+    issuing CA and downloading the CRL file.

+
+    ![pki download crl](/images/platform/pki/ca-crl-modal.png)
+
+    To verify a certificate against the
+    downloaded CRL with OpenSSL, you can use the following command:
+
+```bash
+openssl verify -crl_check -CAfile chain.pem -CRLfile crl.pem certificate.pem
