### `xmlSecCryptoAppPkcs12Load`

```c
xmlSecKeyPtr xmlSecCryptoAppPkcs12Load(const char *filename, const char *pwd, void *pwdCallback, void *pwdCallbackCtx);
```

*Source:* [include/xmlsec/app.h](https://github.com/lsh123/xmlsec/blob/1.3.12/include/xmlsec/app.h#L690)

Reads a key and certificates from a PKCS12 file.

Reads a key and all associated certificates from the PKCS12 file. For uniformity, call xmlSecCryptoAppKeyLoadEx instead of this function. Pass in format=xmlSecKeyDataFormatPkcs12. 

**Parameters:**

- `filename` — the PKCS12 key filename.
- `pwd` — the PKCS12 file password.
- `pwdCallback` — the password callback.
- `pwdCallbackCtx` — the user context for password callback.


**Returns:** pointer to the key or NULL if an error occurs.
