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

17 int des_read_pw(char *buf,char *buff,int size,const char *prompt,int verify);
21 The DES library contained a few routines to prompt for passwords. These
22 aren't necessarely dependent on DES, and have therefore become part of the
23 UI compatibility library.
25 des_read_pw() writes the string specified by I<prompt> to standard output
26 turns echo off and reads an input string from the terminal. The string is
27 returned in I<buf>, which must have spac for at least I<size> bytes.
28 If I<verify> is set, the user is asked for the password twice and unless
29 the two copies match, an error is returned. The second password is stored
30 in I<buff>, which must therefore also be at least I<size> bytes. A return
31 code of -1 indicates a system error, 1 failure due to use interaction, and
32 0 is success. All other functions described here use des_read_pw() to do
35 des_read_pw_string() is a variant of des_read_pw() that provides a buffer
36 for you if I<verify> is set.
38 des_read_password() calls des_read_pw() and converts the password to a
39 DES key by calling DES_string_to_key(); des_read_2password() operates in
40 the same way as des_read_password() except that it generates two keys
41 by using the DES_string_to_2key() function.
45 des_read_pw_string() is available in the MIT Kerberos library as well, and
46 is also available under the name EVP_read_pw_string().
