The
.Li krb5_checksum
structure holds a Kerberos checksum.
.Pp
There is no component inside
.Li krb5_checksum
that is directly referable.
.Pp
The
.Li krb5_enc_data
structure holds and encrypted data.
There are two public accessable members of
.Li krb5_enc_data .
.Li enctype
that holds the encryption type of the data encrypted and
.Li ciphertext
that is a
.Ft krb5_data
that might contain the encrypted data.
.Pp
.Fn krb5_c_block_size
returns the blocksize of the encryption type.
.Pp
.Fn krb5_c_decrypt
decrypts
.Fa input
and store the data in
.Fa output.
If
.Fa ivec
is
.Dv NULL
the default initialization vector for that encryption type will be used.
.Pp
.Fn krb5_c_encrypt
encrypts the plaintext in
.Fa input
and store the ciphertext in
.Fa output .
.Pp
.Fn krb5_c_encrypt_length
returns the length the encrypted data given the plaintext length.
.Pp
.Fn krb5_c_enctype_compare
compares to encryption types and returns if they use compatible
encryption key types.
.Pp
.Fn krb5_c_make_checksum
creates a checksum
