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

144 \&\fBopenssl\fR \fBcrl2pkcs7\fR

146 [\fB\-outform PEM|DER\fR]
147 [\fB\-in filename\fR]

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