|
|
.Sh DESCRIPTION
|
|
Heimdal exports parts of the Kerberos crypto interface for applications.
|
|
.Pp
|
|
Each kerberos encrytion/checksum function takes a crypto context.
|
|
.Pp
|
|
To setup and destroy crypto contextes there are two functions
|
|
.Fn krb5_crypto_init
|
|
and
|
|
.Fn krb5_crypto_destroy .
|
|
The encryption type to use is taken from the key, but can be overridden
|
|
with the
|
|
.Fa enctype parameter .
|
|
This can be useful for encryptions types which is compatiable (DES for
|
|
example).
|
|
.Pp
|
|
.Fn krb5_enctype_to_string
|
|
converts a encryption type number to a string that can be printable
|
|
and stored. The strings returned should be freed with
|
|
.Xr free 3 .
|
|
.Pp
|
|
.Fn krb5_string_to_enctype
|
|
converts a encryption type strings to a encryption type number that
|
|
can use used for other Kerberos crypto functions.
