Hi
I'm currently using C++ on a HP-UX 11i system (upgrading some libraries) and am encountering a problem with the process crashing when allocating memory via a call to new (a rather large array of objects are being created).
Is there a way to find out what the sizes of the stack and heap are?... (1 Reply)

Hi,
If I want to copy a 1024 byte data stream in to the target location in 3-bytes chunk, I guess I can use the following script.
dd bs=1024 count=3 if=/src of=/dest
But, I would like to know, how to do it via a C program. I have tried this with memcpy(), that did not help. (3 Replies)

crypt::des_ede3
Crypt::DES_EDE3(3pm) User Contributed Perl Documentation Crypt::DES_EDE3(3pm)
NAME
Crypt::DES_EDE3 - Triple-DES EDE encryption/decryption
SYNOPSIS
use Crypt::DES_EDE3;
my $ede3 = Crypt::DES_EDE3->new($key);
$ede3->encrypt($block);
DESCRIPTION
Crypt::DES_EDE3 implements DES-EDE3 encryption. This is triple-DES encryption where an encrypt operation is encrypt-decrypt-encrypt, and
decrypt is decrypt-encrypt-decrypt. This implementation uses Crypt::DES to do its dirty DES work, and simply provides a wrapper around that
module: setting up the individual DES ciphers, initializing the keys, and performing the encryption/decryption steps.
DES-EDE3 encryption requires a key size of 24 bytes.
You're probably best off not using this module directly, as the encrypt and decrypt methods expect 8-octet blocks. You might want to use
the module in conjunction with Crypt::CBC, for example. This would be DES-EDE3-CBC, or triple-DES in outer CBC mode.
USAGE
$ede3 = Crypt::DES_EDE3->new($key)
Creates a new Crypt::DES_EDE3 object (really, a collection of three DES ciphers), and initializes each cipher with part of $key, which
should be at least 24 bytes. If it's longer than 24 bytes, the extra bytes will be ignored.
Returns the new object.
$ede3->encrypt($block)
Encrypts an 8-byte block of data $block using the three DES ciphers in an encrypt-decrypt-encrypt operation.
Returns the encrypted block.
$ede3->decrypt($block)
Decrypts an 8-byte block of data $block using the three DES ciphers in a decrypt-encrypt-decrypt operation.
Returns the decrypted block.
$ede3->blocksize
Returns the block size(8).
$ede3->keysize
Returns the key size(24).
