144 crl2pkcs7 \- Create a PKCS#7 structure from a \s-1CRL\s0 and certificates.
146 .IX Header "SYNOPSIS"

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