### LIBRARY

### SYNOPSIS

```krb5_error_code` krb5_rd_priv(```krb5_context context``, krb5_auth_context auth_context``, const krb5_data *inbuf``, krb5_data *outbuf``, krb5_replay_data *outdata`)
```krb5_error_code` krb5_rd_safe(```krb5_context context``, krb5_auth_context auth_context``, const krb5_data *inbuf``, krb5_data *outbuf``, krb5_replay_data *outdata`)

### DESCRIPTION

krb5_rd_safe(``) and krb5_rd_priv(``) parses ```KRB-SAFE` and ```KRB-PRIV` messages (as generated by krb5_mk_safe(3) and krb5_mk_priv(3)) from ```inbuf` and verifies its integrity. The user data part of the message in put in ```outbuf`. The encryption state, including keyblocks and addresses, is taken from ```auth_context`.
