handle long password with HP_IA64

corne_1 — Wed, 11 Oct 2006 17:56:03 GMT

Hello,

It seems crypt() in HP_IA64(Unix) can only encrypt 8 characters long
password, are there any ways to make it encrypt using in MD5 rather
than DES as the GNU crypt() can switch between the two algrorithms? If
not, what other way I can go to handle long password in HP_IA64?

Thanks very much!

Did you try using bigcrypt() ?

Thanks very much, do you think bigcrypt and crpyt generate the same encypted chars if the password is less than 8 chars.

Also in HP_UX, how can I change the makefile in
order to use bigcrypt().

Thanks again1

Yes, bigcrypt() follows the crypt() for password length of 8 characters or less.

crypt() and bigcrypt() are basically DES implementations on HPUX as you might knew. bigcrypt() has upper limit of 40 characters.

You can use "-lsec" with the makefile to use bigcrypt().

Could you supply a quick example on how to use bigcrypt in a short c program that can be called by a script?
