UI_UTIL_read_pw_string, UI_UTIL_read_pw, UI_UTIL_wrap_read_pem_callback - user interface utilities
#include <openssl/ui.h>
int UI_UTIL_read_pw_string(char *buf, int length, const char *prompt, int verify); int UI_UTIL_read_pw(char *buf, char *buff, int size, const char *prompt, int verify); UI_METHOD *UI_UTIL_wrap_read_pem_callback(pem_password_cb *cb, int rwflag);
UI_UTIL_read_pw_string()
asks for a passphrase, using prompt as a
prompt, and stores it in buf.
The maximum allowed size is given with length, including the
terminating NUL byte.
If verify is non-zero, the password will be verified as well.
UI_UTIL_read_pw()
does the same as UI_UTIL_read_pw_string()
, the
difference is that you can give it an external buffer buff for the
verification passphrase.
UI_UTIL_wrap_read_pem_callback()
can be used to create a temporary
UI_METHOD that wraps a given PEM password callback cb.
rwflag is used to specify if this method will be used for
passphrase entry without (0) or with (1) verification.
When not used any more, the returned method should be freed with
UI_destroy_method()
.
UI_UTIL_read_pw_string()
and UI_UTIL_read_pw()
use default
UI_METHOD.
See UI_get_default_method(3) and friends for more information.
The result from the UI_METHOD created by
UI_UTIL_wrap_read_pem_callback()
will generate password strings in the
encoding that the given password callback generates.
The default password prompting functions (apart from
UI_UTIL_read_pw_string()
and UI_UTIL_read_pw()
, there is
PEM_def_callback()
, EVP_read_pw_string()
and EVP_read_pw_string_min())
all use the default UI_METHOD.
UI_UTIL_read_pw_string()
and UI_UTIL_read_pw()
return 0 on success or a negative
value on error.
UI_UTIL_wrap_read_pem_callback()
returns a valid UI_METHOD structure or NULL
if an error occurred.
