# - Unix, Linux Command

# 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

Tag | Description
--- | ---
-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.
