I can view the openSSL certifcate with this command
Code:
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.
Code:
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

nseq
NSEQ(1) OpenSSL NSEQ(1)NAME
nseq - create or examine a netscape certificate sequence
SYNOPSIS
openssl nseq [-in filename] [-out filename] [-toseq]
DESCRIPTION
The nseq command takes a file containing a Netscape certificate sequence and prints out the certificates contained in it or takes a file of
certificates and converts it into a Netscape certificate sequence.
COMMAND OPTIONS -in filename
This specifies the input filename to read or standard input if this option is not specified.
-out filename
specifies the output filename or standard output by default.
-toseq
normally a Netscape certificate sequence will be input and the output is the certificates contained in it. With the -toseq option the
situation is reversed: a Netscape certificate sequence is created from a file of certificates.
EXAMPLES
Output the certificates in a Netscape certificate sequence
openssl nseq -in nseq.pem -out certs.pem
Create a Netscape certificate sequence
openssl nseq -in certs.pem -toseq -out nseq.pem
NOTES
The PEM encoded form uses the same headers and footers as a certificate:
-----BEGIN CERTIFICATE-----
-----END CERTIFICATE-----
A Netscape certificate sequence is a Netscape specific form that can be sent to browsers as an alternative to the standard PKCS#7 format
when several certificates are sent to the browser: for example during certificate enrollment. It is used by Netscape certificate server
for example.
BUGS
This program needs a few more options: like allowing DER or PEM input and output files and allowing multiple certificate files to be used.
