# PKCS12\_add\_safe(3ssl)

Create and add objects to a PKCS#12 structure

## NAME

PKCS12\_add\_safe, PKCS12\_add\_safe\_ex, PKCS12\_add\_safes, PKCS12\_add\_safes\_ex - Create and add objects to a PKCS#12 structure

## SYNOPSIS

```
 #include <openssl/pkcs12.h>
 int PKCS12_add_safe(STACK_OF(PKCS7) **psafes, STACK_OF(PKCS12_SAFEBAG) *bags,
                    int safe_nid, int iter, const char *pass);
 int PKCS12_add_safe_ex(STACK_OF(PKCS7) **psafes, STACK_OF(PKCS12_SAFEBAG) *bags,
                        int safe_nid, int iter, const char *pass,
                        OSSL_LIB_CTX *ctx, const char *propq);
 PKCS12 *PKCS12_add_safes(STACK_OF(PKCS7) *safes, int p7_nid);
 PKCS12 *PKCS12_add_safes_ex(STACK_OF(PKCS7) *safes, int p7_nid,
                             OSSL_LIB_CTX *ctx, const char *propq);
```

## DESCRIPTION

**PKCS12\_add\_safe()** creates a new PKCS7 contentInfo containing the supplied **PKCS12\_SAFEBAG**s and adds this to a set of PKCS7 contentInfos. Its type depends on the value of **safe\_nid**:

- •

  If *safe\_nid* is -1, a plain PKCS7 *data* contentInfo is created.

- •

  If *safe\_nid* is a valid PBE algorithm NID, a PKCS7 **encryptedData** contentInfo is created. The algorithm uses *pass* as the passphrase and *iter* as the iteration count. If *iter* is zero then a default value for iteration count of 2048 is used.

- •

  If *safe\_nid* is 0, a PKCS7 **encryptedData** contentInfo is created using a default encryption algorithm, currently **NID\_pbe\_WithSHA1And3\_Key\_TripleDES\_CBC**.

**PKCS12\_add\_safe\_ex()** is identical to **PKCS12\_add\_safe()** but allows for a library context *ctx* and property query *propq* to be used to select algorithm implementations.

**PKCS12\_add\_safes()** creates a **PKCS12** structure containing the supplied set of PKCS7 contentInfos. The *safes* are enclosed first within a PKCS7 contentInfo of type *p7\_nid*. Currently the only supported type is **NID\_pkcs7\_data**.

**PKCS12\_add\_safes\_ex()** is identical to **PKCS12\_add\_safes()** but allows for a library context *ctx* and property query *propq* to be used to select algorithm implementations.

## NOTES

**PKCS12\_add\_safe()** makes assumptions regarding the encoding of the given pass phrase. See **passphrase-encoding**(7) for more information.

## RETURN VALUES

**PKCS12\_add\_safe()** returns a value of 1 indicating success or 0 for failure.

**PKCS12\_add\_safes()** returns a valid **PKCS12** structure or NULL if an error occurred.

## CONFORMING TO

IETF RFC 7292 (\<https://tools.ietf.org/html/rfc7292\>)
