NAME krb5_string_to_key, krb5_string_to_key_data, krb5_string_to_key_data_salt, krb5_string_to_key_data_salt_opaque, krb5_string_to_key_salt, krb5_string_to_key_salt_opaque, krb5_get_pw_salt, krb5_free_salt — turns a string to a Kerberos key
LIBRARYKerberos 5 Library (libkrb5, -lkrb5)
SYNOPSIS #include <krb5.h>
krb5_error_code krb5_string_to_key ( krb5_context context , krb5_enctype enctype , const char *password , krb5_principal principal , krb5_keyblock *key );
krb5_error_code krb5_string_to_key_data ( krb5_context context , krb5_enctype enctype , krb5_data password , krb5_principal principal , krb5_keyblock *key );
krb5_error_code krb5_string_to_key_data_salt ( krb5_context context , krb5_enctype enctype , krb5_data password , krb5_salt salt , krb5_keyblock *key );
krb5_error_code krb5_string_to_key_data_salt_opaque ( krb5_context context , krb5_enctype enctype , krb5_data password , krb5_salt salt , krb5_data opaque , krb5_keyblock *key );
krb5_error_code krb5_string_to_key_salt ( krb5_context context , krb5_enctype enctype , const char *password , krb5_salt salt , krb5_keyblock *key );
krb5_error_code krb5_string_to_key_salt_opaque ( krb5_context context , krb5_enctype enctype , const char *password , krb5_salt salt , krb5_data opaque , krb5_keyblock *key );
krb5_error_code krb5_get_pw_salt ( krb5_context context , krb5_const_principal principal , krb5_salt *salt );
krb5_error_code krb5_free_salt ( krb5_context context , krb5_salt salt );
DESCRIPTIONThe 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 wrappers 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.
