.. 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'.

way too many mistakes in technical documents.
"NAME"
CMS_EncryptedData_encrypt_ex, CMS_EncryptedData_encrypt \- Create CMS EncryptedData
"SYNOPSIS"
Header "SYNOPSIS" .Vb 1 #include <openssl/cms.h> \& CMS_ContentInfo *CMS_EncryptedData_encrypt_ex(BIO *in, const EVP_CIPHER *cipher, const unsigned char *key, size_t keylen, unsigned int flags, OSSL_LIB_CTX *ctx, const char *propq); \& CMS_ContentInfo *CMS_EncryptedData_encrypt(BIO *in, const EVP_CIPHER *cipher, const unsigned char *key, size_t keylen, unsigned int flags); .Ve
"DESCRIPTION"
Header "DESCRIPTION" \fBCMS_EncryptedData_encrypt_ex() creates a CMS_ContentInfo structure with a type NID_pkcs7_encrypted. in is a \s-1BIO\s0 containing the data to encrypt using cipher and the encryption key key of size keylen bytes. The library context libctx and the property query propq are used when retrieving algorithms from providers. flags is a set of optional flags.

The flags field supports the options \s-1CMS_DETACHED\s0, \s-1CMS_STREAM\s0 and \fB\s-1CMS_PARTIAL\s0. Internally CMS_final() is called unless \s-1CMS_STREAM\s0 and/or \fB\s-1CMS_PARTIAL\s0 is specified.

The algorithm passed in the cipher parameter must support \s-1ASN1\s0 encoding of its parameters.

The CMS_ContentInfo structure can be freed using CMS_ContentInfo_free\|(3).

\fBCMS_EncryptedData_encrypt() is similar to CMS_EncryptedData_encrypt_ex() but uses default values of \s-1NULL\s0 for the library context libctx and the property query propq.

"RETURN VALUES"
Header "RETURN VALUES" If the allocation fails, CMS_EncryptedData_encrypt_ex() and \fBCMS_EncryptedData_encrypt() return \s-1NULL\s0 and set an error code that can be obtained by ERR_get_error\|(3). Otherwise they return a pointer to the newly allocated structure.
"SEE ALSO"
Header "SEE ALSO" \fBERR_get_error\|(3), CMS_final\|(3), CMS_EncryptedData_decrypt\|(3)
"HISTORY"
Header "HISTORY" The CMS_EncryptedData_encrypt_ex() method was added in OpenSSL 3.0.
