NAME

     des_read_password, des_read_2passwords, des_read_pw_string,
     des_read_pw - Compatibility user interface functions

SYNOPSIS

      #include <openssl/des_old.h>

      int des_read_password(DES_cblock *key,const char *prompt,int verify);
      int des_read_2passwords(DES_cblock *key1,DES_cblock *key2,
             const char *prompt,int verify);

      int des_read_pw_string(char *buf,int length,const char *prompt,int verify);
      int des_read_pw(char *buf,char *buff,int size,const char *prompt,int verify);

DESCRIPTION

     The DES library contained a few routines to prompt for
     passwords.  These aren't necessarely dependent on DES, and
     have therefore become part of the UI compatibility library.

     des_read_pw() writes the string specified by prompt to
     standard output turns echo off and reads an input string
     from the terminal.  The string is returned in buf, which
     must have spac for at least size bytes.  If verify is set,
     the user is asked for the password twice and unless the two
     copies match, an error is returned.  The second password is
     stored in buff, which must therefore also be at least size
     bytes.  A return code of -1 indicates a system error, 1
     failure due to use interaction, and 0 is success.  All other
     functions described here use des_read_pw() to do the work.

     des_read_pw_string() is a variant of des_read_pw() that
     provides a buffer for you if verify is set.

     des_read_password() calls des_read_pw() and converts the
     password to a DES key by calling DES_string_to_key();
     des_read_2password() operates in the same way as
     des_read_password() except that it generates two keys by
     using the DES_string_to_2key() function.

NOTES

     des_read_pw_string() is available in the MIT Kerberos
     library as well, and is also available under the name
     EVP_read_pw_string().
