openssl-nseq, nseq - create or examine a Netscape certificate sequence
openssl nseq [-help] [-in filename] [-out filename] [-toseq]
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.
Print out a usage message.
- -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.
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.
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
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 format 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.
This program needs a few more options: like allowing DER or PEM input and output files and allowing multiple certificate files to be used.
