NAME
       CMS_EncryptedData_decrypt - Decrypt CMS EncryptedData

LIBRARY
       libcrypto, -lcrypto

SYNOPSIS
        #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);

DESCRIPTION
       CMS_EncryptedData_decrypt() decrypts a cms EncryptedData object using
       the symmetric key of size keylen bytes. out is a BIO to write the
       content to and flags is an optional set of flags.  dcont is used in the
       rare case where the encrypted content is detached. It will normally be
       set to NULL.

       The following flags can be passed in the flags parameter.

       If the CMS_TEXT flag is set MIME headers for type "text/plain" are
       deleted from the content. If the content is not of type "text/plain"
       then an error is returned.

RETURN VALUES
       CMS_EncryptedData_decrypt() returns 0 if an error occurred otherwise it
       returns 1.
