.. Set up some character translations and predefined strings. \*(-- will
give an unbreakable dash, \*(PI will give pi, \*(L" will give a left
double quote, and \*(R" will give a right double quote. \*(C+ will
give a nicer C++. Capital omega is used to do unbreakable dashes and
therefore won't be available. \*(C` and \*(C' expand to `' in nroff,
nothing in troff, for use with C<>.

Escape single quotes in literal strings from groff's Unicode transform.

If the F register is >0, we'll generate index entries on stderr for
titles (.TH), headers (.SH), subsections (.SS), items (.Ip), and index
entries marked with X<> in POD. Of course, you'll have to process the
output yourself in some meaningful fashion.

Avoid warning from groff about undefined register 'F'.

For nroff, turn off justification. Always turn off hyphenation; it makes
way too many mistakes in technical documents.
"NAME"
CMS_EncryptedData_decrypt \- Decrypt CMS EncryptedData
"SYNOPSIS"
Header "SYNOPSIS" .Vb 1 #include <openssl/cms.h> \& int CMS_EncryptedData_decrypt(CMS_ContentInfo *cms, const unsigned char *key, size_t keylen, BIO *dcont, BIO *out, unsigned int flags); .Ve
"DESCRIPTION"
Header "DESCRIPTION" \fBCMS_EncryptedData_decrypt() decrypts a cms EncryptedData object using the symmetric key of size keylen bytes. out is a \s-1BIO\s0 to write the content to and flags is an optional set of flags. \fIdcont is used in the rare case where the encrypted content is detached. It will normally be set to \s-1NULL.\s0

The following flags can be passed in the flags parameter.

If the \s-1CMS_TEXT\s0 flag is set \s-1MIME\s0 headers for type \*(C`text/plain\*(C' are deleted from the content. If the content is not of type \*(C`text/plain\*(C' then an error is returned.

"RETURN VALUES"
Header "RETURN VALUES" \fBCMS_EncryptedData_decrypt() returns 0 if an error occurred otherwise it returns 1.
