-=head1 NAME
-
-PKCS7_sign - create a PKCS#7 signedData structure
-
-=head1 SYNOPSIS
-
- #include <openssl/pkcs7.h>
-
- PKCS7 *PKCS7_sign(X509 *signcert, EVP_PKEY *pkey, STACK_OF(X509) *certs, BIO *data, int flags);
-
-=head1 DESCRIPTION
-
-PKCS7_sign() creates and returns a PKCS#7 signedData structure. B<signcert> is
-the certificate to sign with, B<pkey> is the corresponding private key.
-B<certs> is an optional additional set of certificates to include in the PKCS#7
-structure (for example any intermediate CAs in the chain).
-
-The data to be signed is read from BIO B<data>.
-
-B<flags> is an optional set of flags.
-
-=head1 NOTES
-
-Any of the following flags (ored together) can be passed in the B<flags>
-parameter.
-
-Many S/MIME clients expect the signed content to include valid MIME headers. If
-the B<PKCS7_TEXT> flag is set MIME headers for type B<text/plain> are prepended
-to the data.
-
-If B<PKCS7_NOCERTS> is set the signer's certificate will not be included in the
-PKCS7 structure, the signer's certificate must still be supplied in the
-B<signcert> parameter though. This can reduce the size of the signature if the
-signers certificate can be obtained by other means: for example a previously
-signed message.
-
-The data being signed is included in the PKCS7 structure, unless
-B<PKCS7_DETACHED> is set in which case it is omitted. This is used for PKCS7
-detached signatures which are used in S/MIME plaintext signed messages for
-example.
-
-Normally the supplied content is translated into MIME canonical format (as
-required by the S/MIME specifications) if B<PKCS7_BINARY> is set no translation
-occurs. This option should be used if the supplied data is in binary format
-otherwise the translation will corrupt it.
-
-The signedData structure includes several PKCS#7 authenticatedAttributes
-including the signing time, the PKCS#7 content type and the supported list of
-ciphers in an SMIMECapabilities attribute. If B<PKCS7_NOATTR> is set then no
-authenticatedAttributes will be used. If B<PKCS7_NOSMIMECAP> is set then just
-the SMIMECapabilities are omitted.
-
-If present the SMIMECapabilities attribute indicates support for the following
-algorithms: triple DES, 128 bit RC2, 64 bit RC2, DES and 40 bit RC2. If any of
-these algorithms is disabled then it will not be included.
-
-If the flags B<PKCS7_STREAM> is set then the returned B<PKCS7> structure is
-just initialized ready to perform the signing operation. The signing is however
-B<not> performed and the data to be signed is not read from the B<data>
-parameter. Signing is deferred until after the data has been written. In this
-way data can be signed in a single pass.
-
-If the B<PKCS7_PARTIAL> flag is set a partial B<PKCS7> structure is output to
-which additional signers and capabilities can be added before finalization.
-
-
-=head1 NOTES
-
-If the flag B<PKCS7_STREAM> is set the returned B<PKCS7> structure is B<not>
-complete and outputting its contents via a function that does not properly
-finalize the B<PKCS7> structure will give unpredictable results.
-
-Several functions including SMIME_write_PKCS7(), i2d_PKCS7_bio_stream(),
-PEM_write_bio_PKCS7_stream() finalize the structure. Alternatively finalization
-can be performed by obtaining the streaming ASN1 B<BIO> directly using
-BIO_new_PKCS7().
-
-If a signer is specified it will use the default digest for the signing
-algorithm. This is B<SHA1> for both RSA and DSA keys.
-
-In OpenSSL 1.0.0 the B<certs>, B<signcert> and B<pkey> parameters can all be
-B<NULL> if the B<PKCS7_PARTIAL> flag is set. One or more signers can be added
-using the function B<PKCS7_sign_add_signer()>. B<PKCS7_final()> must also be
-called to finalize the structure if streaming is not enabled. Alternative
-signing digests can also be specified using this method.
-
-In OpenSSL 1.0.0 if B<signcert> and B<pkey> are NULL then a certificates only
-PKCS#7 structure is output.
-
-In versions of OpenSSL before 1.0.0 the B<signcert> and B<pkey> parameters must
-B<NOT> be NULL.
-
-=head1 BUGS
-
-Some advanced attributes such as counter signatures are not supported.
-
-=head1 RETURN VALUES
-
-PKCS7_sign() returns either a valid PKCS7 structure or NULL if an error
-occurred.  The error can be obtained from ERR_get_error(3).
