#include

int
UI_UTIL_read_pw_string(char
*buf, int length, const char
*prompt, int verify);

UI_UTIL_read_pw(char *buf,
char *buff, int size,
const char *prompt, int
verify);
DESCRIPTION
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(), but takes
an external buffer buff for the verification
passphrase.
RETURN VALUES
UI_UTIL_read_pw_string() and
UI_UTIL_read_pw() return 0 on success or a negative
value on error.
