147 \&\fBopenssl\fR \fBpkcs7\fR
148 [\fB\-inform PEM|DER\fR]
149 [\fB\-outform PEM|DER\fR]
150 [\fB\-in filename\fR]
151 [\fB\-out filename\fR]
152 [\fB\-print_certs\fR]
156 .IX Header "DESCRIPTION"
157 The \fBpkcs7\fR command processes PKCS#7 files in \s-1DER\s0 or \s-1PEM\s0 format.
158 .SH "COMMAND OPTIONS"
159 .IX Header "COMMAND OPTIONS"
160 .Ip "\fB\-inform DER|PEM\fR" 4
161 .IX Item "-inform DER|PEM"
162 This specifies the input format. \fB\s-1DER\s0\fR format is \s-1DER\s0 encoded PKCS#7
163 v1.5 structure.\fB\s-1PEM\s0\fR (the default) is a base64 encoded version of
164 the \s-1DER\s0 form with header and footer lines.
165 .Ip "\fB\-outform DER|PEM\fR" 4
166 .IX Item "-outform DER|PEM"
167 This specifies the output format, the options have the same meaning as the
168 \&\fB\-inform\fR option.
169 .Ip "\fB\-in filename\fR" 4
170 .IX Item "-in filename"
171 This specifies the input filename to read from or standard input if this
172 option is not specified.
173 .Ip "\fB\-out filename\fR" 4
174 .IX Item "-out filename"
175 specifies the output filename to write to or standard output by
177 .Ip "\fB\-print_certs\fR" 4
178 .IX Item "-print_certs"
179 prints out any certificates or CRLs contained in the file. They are
180 preceded by their subject and issuer names in one line format.
183 prints out certificates details in full rather than just subject and
185 .Ip "\fB\-noout\fR" 4
187 don't output the encoded version of the PKCS#7 structure (or certificates
188 is \fB\-print_certs\fR is set).
190 .IX Header "EXAMPLES"
191 Convert a PKCS#7 file from \s-1PEM\s0 to \s-1DER:\s0
194 \& openssl pkcs7 -in file.pem -outform DER -out file.der
196 Output all certificates in a file:
199 \& openssl pkcs7 -in file.pem -print_certs -out certs.pem
203 The \s-1PEM\s0 PKCS#7 format uses the header and footer lines:
206 \& -----BEGIN PKCS7-----
207 \& -----END PKCS7-----
209 For compatability with some CAs it will also accept:
212 \& -----BEGIN CERTIFICATE-----
213 \& -----END CERTIFICATE-----
216 .IX Header "RESTRICTIONS"
217 There is no option to print out all the fields of a PKCS#7 file.
219 This PKCS#7 routines only understand PKCS#7 v 1.5 as specified in \s-1RFC2315\s0 they
220 cannot currently parse, for example, the new \s-1CMS\s0 as described in \s-1RFC2630\s0.
