The krb5_enc_data structure holds and
    encrypted data. There are two public accessible members of
    krb5_enc_data. enctype that
    holds the encryption type of the data encrypted and
    ciphertext that is a krb5_data
    that might contain the encrypted data.
krb5_c_block_size() returns the blocksize
    of the encryption type.
krb5_c_decrypt() decrypts
    input and store the data in
    output. If ivec is
    NULL the default initialization vector for that
    encryption type will be used.
krb5_c_encrypt() encrypts the plaintext in
    input and store the ciphertext in
    output.
krb5_c_encrypt_length() returns the length
    the encrypted data given the plaintext length.
krb5_c_enctype_compare() compares to
    encryption types and returns if they use compatible encryption key
  types.
krb5_c_make_checksum() creates a checksum
    cksum with the checksum type
    cksumtype of the data in data.
    key and usage are used if the
    checksum is a keyed checksum type. Returns 0 or an error code.
krb5_c_verify_checksum() verifies the
    checksum of data in cksum that
    was created with key using the key usage
    usage. verify is set to non-zero
    if the checksum verifies correctly and zero if not. Returns 0 or an error
    code.
krb5_c_checksum_length() returns the
    length of the checksum.
krb5_c_set_checksum() sets the
    krb5_checksum structure given
    type and data. The content of
    cksum should be freeed with
    krb5_c_free_checksum_contents().
krb5_c_get_checksum() retrieves the
    components of the krb5_checksum. structure.
    data should be free with
    krb5_free_data(). If some either of
    data or checksum is not needed
    for the application, NULL can be passed in.
krb5_c_valid_enctype() returns true if
    etype is a valid encryption type.
krb5_c_valid_cksumtype() returns true if
    ctype is a valid checksum type.
krb5_c_is_keyed_cksum() return true if
    ctype is a keyed checksum type.
krb5_c_is_coll_proof_cksum() returns true
    if ctype is a collision proof checksum type.
krb5_c_keylengths() return the minimum
    length (inlength) bytes needed to create a key and the
    length (keylength) of the resulting key for the
    enctype.
