This version of mkpasswd can create both DES and MD5 passwords, with |
| 7 |
|
|
either randomly generated or user provided salts. |

Without the presence of any parameters, it'll behave like the old mkpasswd, |
| 24 |
|
|
creating a DES password with a randomly generated salt and prompting for |
| 25 |
|
|
the password (without echo). |
| 26 |
|
|
|
| 27 |
|
|
A DES salt is a pair of alphanumeric characters ('.' and '/' are permitted |
| 28 |
|
|
as well), such as 'a4' or 'Td'. |
| 29 |
|
|
|
| 30 |
|
|
An MD5 salt consists of up to 16 (though most implementations limit you to |
| 31 |
|
|
8) alphanumeric characters (plus '.' and '/'), |
| 32 |
|
|
such as 'tGd' or 'J6d4dfG'. |

|
Known bugs: |
| 35 |
|
|
Blowfish (on OpenBSD) is not yet supported |
| 36 |
|
|
The encryption algorithms supported depend on your system's crypt() |
| 37 |
|
|
implementation. |
| 38 |
|
|
The maximum length of an MD5 salt is limited to your systems crypt() |
| 39 |
|
|
implementation, typically 8. |

|
Supported Platforms (Known and tested): |
| 42 |
|
|
Linux glibc (DES and MD5) |
| 43 |
|
|
FreeBSD 3.x (DES (MD5 maybe)) |
| 44 |
|
|
FreeBSD 4.x (DES and MD5) |
| 45 |
|
|
Solaris 2.5-2.6 (DES only) |
| 46 |
|
|
Cygwin 1.1.4 (DES only) |
| 47 |
|
|
Prior Cygwin with the MD5 libcrypt (MD5 only) |
| 48 |
|
|
OpenBSD 2.7 (don't link with -lcrypt) (DES and MD5, no Blowfish support) |
| 49 |
|
|
Mac OS-X (Darwin) (don't link with -lcrypt) (DES only) |
| 50 |
|
|
|
| 51 |
|
|
Other systems probably work, but they haven't been amply tested. |
