DESCRIPTION
holds the encryption key for a specific encryption type. There is no component inside krb5_keyblock that is directly referable.
krb5_keyblock_get_enctype returns the encryption type of the keyblock.
krb5_copy_keyblock makes a copy the keyblock inblock to the output out . out should be freed by the caller with krb5_free_keyblock .
krb5_copy_keyblock_contents copies the contents of inblock to the to keyblock. The destination keyblock is overritten.
krb5_free_keyblock zeros out and frees the content and the keyblock itself.
krb5_free_keyblock_contents zeros out and frees the content of the keyblock.
krb5_generate_random_keyblock creates a new content of the keyblock key of type encrytion type type . The content of key is overwritten and not freed, so the caller should be sure it is freed before calling the function.
krb5_generate_subkey generates a subkey of the same type as key . The caller must free the subkey with krb5_free_keyblock .
krb5_generate_subkey_extended generates a subkey of the specified encryption type type . If type is ETYPE_NULL , of the same type as key . The caller must free the subkey with krb5_free_keyblock .
krb5_keyblock_init Fill in key with key data of type enctype from data of length size . Key should be freed using krb5_free_keyblock_contents .
krb5_keyblock_zero zeros out the keyblock to to make sure no keymaterial is in memory. Note that krb5_free_keyblock_contents also zeros out the memory.
krb5_random_to_key converts the random bytestring to a protocol key according to Kerberos crypto frame work. It the resulting key will be of type enctype . It may be assumed that all the bits of the input string are equally random, even though the entropy present in the random source may be limited
