UI_UTIL_READ_PW(3)         Library Functions Manual         UI_UTIL_READ_PW(3)

NAME
     UI_UTIL_read_pw, UI_UTIL_read_pw_string - get a password from the user

SYNOPSIS
     #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);

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.
