nseq

NAME

openssl-nseq, nseq - create or examine a Netscape certificate sequence

SYNOPSIS

openssl nseq [-help] [-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.

OPTIONS

-help

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.

-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 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.

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.
