# [DESCRIPTION](#DESCRIPTION)

[`krb5_rd_safe`](#krb5_rd_safe)() and [`krb5_rd_priv`](#krb5_rd_priv)() parses `KRB-SAFE` and `KRB-PRIV` messages (as generated by [krb5\_mk\_safe(3)](/man/os/heimdal/krb5_mk_safe.3) and [krb5\_mk\_priv(3)](/man/os/heimdal/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`. If the `KRB5_AUTH_CONTEXT_RET_SEQUENCE` or `KRB5_AUTH_CONTEXT_RET_TIME` flags are set in the `auth_context` the sequence number and time are returned in the `outdata` parameter.
