 Where `mycerts.pub` is the file containing the certificate chain from signing certificate to the last certificate before the root CA, concatenated.
 
-This command produces a text summary of the certificate properties, as shown in the example below. Look for a line containing `Signature Algorithm`. The public key indicates the signature algorithm used. See the table in [Getting a certificate](get-cert.md#signature-types) to determine the corresponding signature type.
