133 crl2pkcs7 \- Create a PKCS#7 structure from a CRL and certificates.

136 \&\fBopenssl\fR \fBcrl2pkcs7\fR

138 [\fB\-outform PEM|DER\fR]
139 [\fB\-in filename\fR]

141 [\fB\-certfile filename\fR]
144 .IX Header "DESCRIPTION"
145 The \fBcrl2pkcs7\fR command takes an optional \s-1CRL\s0 and one or more
146 certificates and converts them into a PKCS#7 degenerate \*(L"certificates
148 .SH "COMMAND OPTIONS"
149 .IX Header "COMMAND OPTIONS"
150 .IP "\fB\-inform DER|PEM\fR" 4
151 .IX Item "-inform DER|PEM"
152 This specifies the \s-1CRL\s0 input format. \fB\s-1DER\s0\fR format is \s-1DER\s0 encoded \s-1CRL\s0
153 structure.\fB\s-1PEM\s0\fR (the default) is a base64 encoded version of
154 the \s-1DER\s0 form with header and footer lines.
155 .IP "\fB\-outform DER|PEM\fR" 4
156 .IX Item "-outform DER|PEM"
157 This specifies the PKCS#7 structure output format. \fB\s-1DER\s0\fR format is \s-1DER\s0
158 encoded PKCS#7 structure.\fB\s-1PEM\s0\fR (the default) is a base64 encoded version of
159 the \s-1DER\s0 form with header and footer lines.
160 .IP "\fB\-in filename\fR" 4
161 .IX Item "-in filename"
162 This specifies the input filename to read a \s-1CRL\s0 from or standard input if this
163 option is not specified.
164 .IP "\fB\-out filename\fR" 4
165 .IX Item "-out filename"
166 specifies the output filename to write the PKCS#7 structure to or standard
168 .IP "\fB\-certfile filename\fR" 4
169 .IX Item "-certfile filename"
170 specifies a filename containing one or more certificates in \fB\s-1PEM\s0\fR format.
171 All certificates in the file will be added to the PKCS#7 structure. This
172 option can be used more than once to read certificates form multiple
174 .IP "\fB\-nocrl\fR" 4
176 normally a \s-1CRL\s0 is included in the output file. With this option no \s-1CRL\s0 is
177 included in the output file and a \s-1CRL\s0 is not read from the input file.
179 .IX Header "EXAMPLES"
180 Create a PKCS#7 structure from a certificate and \s-1CRL:\s0
183 \& openssl crl2pkcs7 \-in crl.pem \-certfile cert.pem \-out p7.pem
186 Creates a PKCS#7 structure in \s-1DER\s0 format with no \s-1CRL\s0 from several
187 different certificates:
190 \& openssl crl2pkcs7 \-nocrl \-certfile newcert.pem
191 \& \-certfile demoCA/cacert.pem \-outform DER \-out p7.der
195 The output file is a PKCS#7 signed data structure containing no signers and
196 just certificates and an optional \s-1CRL\s0.
198 This utility can be used to send certificates and CAs to Netscape as part of
199 the certificate enrollment process. This involves sending the \s-1DER\s0 encoded output
200 as \s-1MIME\s0 type application/x\-x509\-user\-cert.
202 The \fB\s-1PEM\s0\fR encoded form with the header and footer lines removed can be used to
203 install user certificates and CAs in \s-1MSIE\s0 using the Xenroll control.
