# PKCS12\_pack\_p7encdata(3ssl)

Pack a set of PKCS#12 safeBags into a PKCS#7 encrypted data object

## 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

IETF RFC 2315 (\<https://tools.ietf.org/html/rfc2315\>)
