Reads cert from `secItem` and adds to the list of trusted or known untrusted certs in `store`

`mngr` : | the pointer to keys manager.
`secItem` : | the pointer to SECItem.
`format` : | the certificate format (PEM or DER).
`type` : | the certificate type (trusted/untrusted).
Returns : | 0 on success or a negative value otherwise.

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

`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.

Reads key and all associated certificates from the PKCS12 binary data. For uniformity, call xmlSecNssAppKeyLoad instead of this function. Pass in format=xmlSecKeyDataFormatPkcs12.

`data` : | the key binary data.
`dataSize` : | the key binary data size.
`pwd` : | the PKCS12 password.
`pwdCallback` : | the password callback.
`pwdCallbackCtx` : | the user context for password callback.
Returns : | pointer to the key or NULL if an error occurs.
