# NAME

PKCS12_pack_p7encdata, PKCS12_pack_p7encdata_ex - Pack a set of PKCS#12 safeBags into a PKCS#7 encrypted data object

# SYNOPSIS

     #include <openssl/pkcs12.h>
     PKCS7 *PKCS12_pack_p7encdata(int pbe_nid, const char *pass, int passlen,
                                  unsigned char *salt, int saltlen, int iter,
                                  STACK_OF(PKCS12_SAFEBAG) *bags);
     PKCS7 *PKCS12_pack_p7encdata_ex(int pbe_nid, const char *pass, int passlen,
                                     unsigned char *salt, int saltlen, int iter,
                                     STACK_OF(PKCS12_SAFEBAG) *bags,
                                     OSSL_LIB_CTX *ctx, const char *propq);

# DESCRIPTION

PKCS12_pack_p7encdata() generates a PKCS#7 ContentInfo object of encrypted-data type from the set of safeBags bags. The algorithm ID in pbe_nid can be a PKCS#12 or PKCS#5 password based encryption algorithm, or a cipher algorithm. If a cipher algorithm is passed, the PKCS#5 PBES2 algorithm will be used with this cipher as a parameter. The password pass of length passlen, salt salt of length saltlen and iteration count iter are inputs into the encryption operation.

PKCS12_pack_p7encdata_ex() operates similar to the above but allows for a library context ctx and property query propq to be used to select the algorithm implementation.

# RETURN VALUES

A PKCS7 object if successful, or NULL if an error occurred.

# CONFORMING TO
