Re: [Freedos-user] encryption program
I don't believe we can use this in FreeDOS. There is no information in the tar file to indicate the distribution license, so I am unsure how this was meant to be redistributed. But the most obvious blocker is that this program is patent-encumbered, and cannot be used commercially (all users of the FreeDOS distribution should be free to use all parts of the system, whether or not they are commercial entities or home users.) Here is the bit from the included man page: >PATENT > IDEA is registered as the international patent WO 91/18459 > "Device for Converting a Digital Block and the Use thereof". > For commercial use of IDEA, one should contact [...] And looking up the patent, I see it was issued 1991 with a US patent issued 2001. -jh On 4/2/07, ice <[EMAIL PROTECTED]> wrote: > Hello. > > I would suggest to add into FreeDOS any encryption utility, as "crypt" > in the FreeBSD for example. > > http://vmsone.com/~decuslib/decus/secure/idea_v1_1.tar_z : IDEA > implementation, easy to compile with "Pacific C for MS-DOS, v7.51" and > "DJGPP Version 2.03". > - Take Surveys.

IDEA is not a free cryptographic algorithm. Its licence prohibites the use in some cases (have a look at http://www.mediacrypt.com/ as the patent holder for idea). Norbert - Take Surveys. Earn Cash.

[Freedos-user] encryption program
Hello. I would suggest to add into FreeDOS any encryption utility, as "crypt" in the FreeBSD for example. http://vmsone.com/~decuslib/decus/secure/idea_v1_1.tar_z : IDEA implementation, easy to compile with "Pacific C for MS-DOS, v7.51" and "DJGPP Version 2.03". -- ice <0x696365*gmail,com> - Take Surveys.
