[Bcrypt-users] Trouble compiling BCrypt source with GCC in Cygwin

[Josh W. <Jwi...@ni...>]

Hello All,

=20

I graduated from UCI a few years back and no longer have access to UNIX
to compile my programs. It's been a while since I've compiled C code in
Windows, so I'm looking for some help.=20

=20

I installed Cygwin with the GCC 3.4.4-3, GDB, and Make packages. When I
try to compile the unedited BCrypt source using the make command, I get
a number of errors (see below).=20

=20

Does anyone have any suggestions? Is it something to do with the
zlib.dll header file?

=20

Thanks!

Hi all,

I'm trying to decrypt a 995MB file, and keep receiving the following
error:

"Can't allocate memory. Bailing out"

The system itself has 6GB of RAM, with at least 4.5GB of 'free' memory.

How much memory is required to decrypt a 995MB file? Shouldn't 4.5GB of
memory be adequate?

[Bcrypt-users] Interoperability Java & C/C++ using bcrypt

[<Joe...@t-...>]

Hi there,

Does anybody knows something about the interoperability between
encryption using the crypto-Package of the J2SE and using bcrypt on the
other hand?
Which parameters (padding, etc.) do I have to set in my Java-Source, in
order to be able to decrypt a file with bcrypt, that has bin encrypted
by java and vice versa?

Re: [Bcrypt-users] bcrypt - how to setup a key phrase file

[Jared K. <ci...@ma...>]

Bcrypt is a dead source tree (won't even support files over 2 gig).  If
I were you I would look to PGP for UNIX instead.  If you really want to
use bcrypt in the manner you've stated, I'd suggest doing it via an
Expect script.

[Bcrypt-users] bcrypt - how to setup a key phrase file

[Jani T. <jta...@gm...>]

I am trying to setup some automated scripts to encrypt files on Solaris 8.

When I try: bcrypt <original_file> <new_file> -v , it sks me to for the
encryption key. When I type the encryption key, it encrypts the file.

I want to automate this process ie. I want to input the encryption key
through a file. How do I do this? Man page does not explain much on this.

Thanks, Janni

Hello,

    I'm using the brcypt tool on w2k server SP4.
    I wrote a Winbatch script to decrypt the file.
    This script works fine when directly launched on the server.
    "...
     If FileExist ("%adminpath%\bcrypt.cmd")
     run ("%adminpath%\bcrypt.cmd","")
     SendKeysTo ("~cmd.exe", "pswd")
     SendKeysTo ("~cmd.exe", "{ENTER}")
     ..."
=0D
    bcrypt.cmd file :
    d:\bsutools\tools\bcrypt\bcrypt.exe
\\servername\applications\dbxxx\filename.csv.bfe
=0D
    I have a problem when I try to launch it via the Schedule task (with
admin user) or via maestro (scheduler tool).
    I think there is a problem to pass the parameter.
=0D
    Can someone help me about this ?

[Bcrypt-users] FASD project: Online survey launched

[<ben...@id...>]

Dear Open Source developer

I am doing a research project on "Fun and Software Development" in which I kindly invite you to participate.
You will find the online survey under http://fasd.ethz.ch/qsf/. The questionnaire consists of 53 questions and you will need about 15 minutes to complete it.

With the FASD project (Fun and Software Development) we want to define the motivational significance of fun when software developers decide to engage in Open Source projects. What is special about our research project is that a similar survey is planned with software developers in commercial firms. This procedure allows the immediate comparison between the involved individuals and the conditions of production of these two development models. Thus we hope to obtain substantial new insights to the phenomenon of Open Source Development.


With many thanks for your participation,
Benno Luthiger


PS:
The results of the survey will be published under http://www.isu.unizh.ch/fuehrung/blprojects/FASD/.
We have set up the mailing list fa...@we... for this study. Please see http://fasd.ethz.ch/qsf/mailinglist_en.html for registration to this mailing list.

[Bcrypt-users] bcrypt keylength

[Lars T. B. <lar...@ne...>]

Hi!

If I want to increase/decrease the keylength from 448 bits to X bits,
will it suffice to change line 8 in blowfish.h:
#define MAXKEYBYTES 56          /* 448 bits */
to another MAXKEYBYTES value?

Does this implementation use EBC or CBC mode?

Thanks for your time and answers!

Tobias

This is considered a security hole, as any user would be able to see
the password on the process list.  One workaround, assuming you trust
your filesystem, is to pipe the arguments in with '<' and '>'.  In
short, to automatically encrypt, have a file named foo with the
password repeated twice, and use "bcrypt filename < foo" to encrypt
it.  To decrypt, have a filename with the password (only once) named
bar, and use "bcrypt filename < bar" to decrypt.

[Bcrypt-users] bcrypt 1.1 encryption mode

[Michael M. <mg...@es...>]

Hi there,

I've just found bcrypt on freshmeat, whilst looking for utilities for
encrypting files with a view to using rsync to store encrypted offsite
backups. I'm interested in encryption that doesn't break rsync's remote
diff behaviour, whilst still being strong crypto. I've run a few tests on
the output from bcrypt and was wondering if anyone could comment on the
following:

 - if I encrypt identical files with the same passphrase, I get the same
output. Have I just been lucky or is this guaranteed? (You can avoid it by
"seeding" the blocks to encrypt with a random starting block which you
discard when decrypting).

 - if I encrypt two files which are identical except for a new block of
2048 bytes in the middle, bdiff tells me that the encrypted files differ
by around 4000 bytes (i.e. a value close to the difference between the
files). Does this make sense?

What I think is that the encryption works in some sort of mode where the
results of encrypting previous blocks does not affect encryption of future
blocks. Is this correct?

Finally, does anyone have comments on the security of the bcrypt utility?
Is the security roughly as good as my key choice?

Thanks,
Mike.
