=head1 DESCRIPTION
PKCS7_sign() creates and returns a PKCS#7 signedData structure. B<signcert> is
-the certificate to sign with, B<pkey> is the corresponsding private key.
+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).
+structure (for example any intermediate CAs in the chain).
The data to be signed is read from BIO B<data>.
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
+using the function PKCS7_sign_add_signer(). 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.

=head1 HISTORY
-PKCS7_sign() was added to OpenSSL 0.9.5
-
-The B<PKCS7_PARTIAL> flag was added in OpenSSL 1.0.0
+The B<PKCS7_PARTIAL> flag, and the ability for B<certs>, B<signcert>,
+and B<pkey> parameters to be B<NULL> to be was added in OpenSSL 1.0.0
The B<PKCS7_STREAM> flag was added in OpenSSL 1.0.0
