PKCS#7 command

## NAME

openssl-pkcs7 - PKCS#7 command

## SYNOPSIS

**openssl** **pkcs7** \[**-help**\] \[**-inform** **DER**\|**PEM**\] \[**-outform** **DER**\|**PEM**\] \[**-in** *filename*\] \[**-out** *filename*\] \[**-print**\] \[**-print\_certs**\] \[**-quiet**\] \[**-text**\] \[**-noout**\] \[**-engine** *id*\] \[**-provider** *name*\] \[**-provider-path** *path*\] \[**-provparam** *\[name:\]key=value*\] \[**-propquery** *propq*\]

## DESCRIPTION

This command processes PKCS#7 files.  Note that it only understands PKCS#7 v 1.5 as specified in IETF RFC 2315.  It cannot currently parse CMS as described in IETF RFC 2630.

## OPTIONS

- **-help**

  Print out a usage message.

- **-inform** **DER**\|**PEM**, **-outform** **DER**\|**PEM**

  The input and formats; the default is **PEM**. See **openssl-format-options**(1) for details.

  The data is a PKCS#7 Version 1.5 structure.

- **-in** *filename*

  This specifies the input filename to read from or standard input if this option is not specified.

- **-out** *filename*

  Specifies the output filename to write to or standard output by default.

- **-print**

  Print out the full PKCS7 object.

- **-print\_certs**

  Prints out any certificates or CRLs contained in the file. They are preceded by their subject and issuer names in one line format.

- **-quiet**

  When used with -print\_certs, prints out just the PEM-encoded  certificates without any other output.

- **-text**

  Prints out certificate details in full rather than just subject and issuer names.

- **-noout**

  Don't output the encoded version of the PKCS#7 structure (or certificates if **-print\_certs** is set).

- **-engine** *id*

  See "Engine Options" in [**openssl**(1)](/openssl/1.md). This option is deprecated.

- **-provider** *name*

  - **-provider-path** *path*

  - **-provparam** *\[name:\]key=value*

  - **-propquery** *propq*

  See "Provider Options" in [**openssl**(1)](/openssl/1.md), **provider**(7), and **property**(7).

## EXAMPLES

Convert a PKCS#7 file from PEM to DER:

```
 openssl pkcs7 -in file.pem -outform DER -out file.der
```

Output all certificates in a file:

```
 openssl pkcs7 -in file.pem -print_certs -out certs.pem
```
