DESCRIPTION
The string to key functions convert a string to a kerberos key.
krb5_string_to_key_data_salt_opaque() is the function that does all the
work, the rest of the functions are just wrapers around
krb5_string_to_key_data_salt_opaque() that calls it with default values.
krb5_string_to_key_data_salt_opaque() transforms the password with the
given salt-string salt and the opaque, encryption type specific parameter
opaque to a encryption key key according to the string to key function
associated with enctype.
The key should be freed with krb5_free_keyblock_contents().
If one of the functions that doesn't take a krb5_salt as it argument
krb5_get_pw_salt() is used to get the salt value.
krb5_get_pw_salt() get the default password salt for a principal, use
krb5_free_salt() to free the salt when done.
krb5_free_salt() frees the content of salt.
