144 SMIME_write_PKCS7 \- convert PKCS#7 structure to S/MIME format.
148 .IX Header "SYNOPSIS"
150 \& #include <openssl/pkcs7.h>
152 \& int SMIME_write_PKCS7(BIO *out, PKCS7 *p7, BIO *data, int flags);
155 .IX Header "DESCRIPTION"
156 \&\fISMIME_write_PKCS7()\fR adds the appropriate \s-1MIME\s0 headers to a PKCS#7
157 structure to produce an S/MIME message.
159 \&\fBout\fR is the \s-1BIO\s0 to write the data to. \fBp7\fR is the appropriate \fB\s-1PKCS7\s0\fR
160 structure. If streaming is enabled then the content must be supplied in the
161 \&\fBdata\fR argument. \fBflags\fR is an optional set of flags.
164 The following flags can be passed in the \fBflags\fR parameter.
166 If \fB\s-1PKCS7_DETACHED\s0\fR is set then cleartext signing will be used,
167 this option only makes sense for signedData where \fB\s-1PKCS7_DETACHED\s0\fR
168 is also set when \fIPKCS7_sign()\fR is also called.
170 If the \fB\s-1PKCS7_TEXT\s0\fR flag is set \s-1MIME\s0 headers for type \fBtext/plain\fR
171 are added to the content, this only makes sense if \fB\s-1PKCS7_DETACHED\s0\fR
174 If the \fB\s-1PKCS7_STREAM\s0\fR flag is set streaming is performed. This flag should
175 only be set if \fB\s-1PKCS7_STREAM\s0\fR was also set in the previous call to
176 \&\fIPKCS7_sign()\fR or \fB\f(BIPKCS7_encrypt()\fB\fR.
178 If cleartext signing is being used and \fB\s-1PKCS7_STREAM\s0\fR not set then
179 the data must be read twice: once to compute the signature in \fIPKCS7_sign()\fR
180 and once to output the S/MIME message.
182 If streaming is performed the content is output in \s-1BER\s0 format using indefinite
183 length constructuted encoding except in the case of signed data with detached
184 content where the content is absent and \s-1DER\s0 format is used.
187 \&\fISMIME_write_PKCS7()\fR always base64 encodes PKCS#7 structures, there
188 should be an option to disable this.
190 .IX Header "RETURN VALUES"
191 \&\fISMIME_write_PKCS7()\fR returns 1 for success or 0 for failure.
