Grep from a certificate

Shell Programming and Scripting
1

I can view the openSSL certifcate with this command

openssl x509 -text -in myCertificate.pem

I just wanted to see when the cert will expire only. The line which I want to read is,
Not After : Jul 28 14:09:57 2015 GMT
I tried using the grep command but it doesn't display anything.

grep "After" myCertificate.pem

Is there a way that I can read only that line of the certificate?? If not with grep then maybe with some other command.
Thanks in advance

That certificate will be encoded, not clear text. grep works on clear text. Try

openssl x509 -text -in myCertificate.pem | grep After
