krb5_rd_cred - Read and validate a KRB-CRED message.
======================================================
..
.. c:function:: krb5_error_code krb5_rd_cred(krb5_context context, krb5_auth_context auth_context, krb5_data * creddata, krb5_creds *** creds_out, krb5_replay_data * rdata_out)
..
:param:
**[in]** **context** - Library context
**[in]** **auth_context** - Authentication context
**[in]** **creddata** - **KRB-CRED** message
**[out]** **creds_out** - Null-terminated array of forwarded credentials
**[out]** **rdata_out** - Replay data (NULL if not needed)
..
:retval:
- 0 Success; otherwise - Kerberos error codes
..
*creddata* will be decrypted using the receiving subkey if it is present in *auth_context* , or the session key if the receiving subkey is not present or fails to decrypt the message.
Use :c:func:`krb5_free_tgt_creds()` to free *creds_out* when it is no longer needed.
..
.. note::
The *rdata_out* argument is required if the :data:`KRB5_AUTH_CONTEXT_RET_TIME` or :data:`KRB5_AUTH_CONTEXT_RET_SEQUENCE` flag is set in *auth_context* .`
