Do you need it to encrypt unreadable skill files ?

What content does the ile file have ?
 
i want to de-encrypt a encrypt skill files ,
which i know the password. As u know, we can
read it by 'lineread' , but if there's passwd,
even if i know it , cant read it.
 
Encryption with a password prevents the unencryption
by lineread.
There is no way to decrypt actually with a standard
Cadence license.

But there is at least one exception.

If the encrypted skill files describes a pcell,
load it to build the pcell and use
dbWriteSkill to dump the plain unencryped content :)
 
oops... got it~~ thx a lot~~ :)

anyway, i just wanna to know if there's any
'option' of the 'lineread' function as if i
'v got the passwd already~~

thx ~

You can't, that would be too easy.

One way or the other, your foundry or whoever has to provide you with
the password- that doesn't mean they want to give you access to the
source code.

That's the whole point password-encrypting your skill files.

Get in touch with the owner if you really need the source.

thx~~ acturally, i'v the source code, i just
wander if it's possible to read it out after
a pw was set, and by the way, the pw is public.

:)

No, it isn't. Even if you know the password, you can't use the known tricks to
read the password file. As for Guenther's exception - it would be fairly
unusual to provide encrypted SKILL for defining the pcell, since there is no
need to ship the code for defining a pcell (since it is stored within the
cellView), unless that code is for additional functions called within the
pcell - in which case Guenther's trick won't work...

Regards,

Andrew.
 
Kholdoun,

that is a hard statement... There are always more ways to Rome than we
can imagine :)

Hi Fogh,

My corrected statement :
"There are no (standard, legal, documented, supported) public
methods to decrypt a password encrypted Skill code, using a
standard Cadence licence."

Cheers,

Ask the true owner for the password.
Oh, you have the password, you say.

Ask the true owner for the source code.
Oh, you have the source code, you say.

Why am I confused about the question & the true source of the file?
