132 .TH CRL2PKCS7 1 "2010-03-24" "0.9.8n" "OpenSSL"
134 crl2pkcs7 \- Create a PKCS#7 structure from a CRL and certificates.
136 .IX Header "SYNOPSIS"

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