I have something like so:

sub build_a_hash_table
{
my(%hash_table);
#some code to build hash table: "%hash_table" for e.g
return %hash_table;
}

Hi:
How do I pass a hash table down to a subroutine along with some other variables?
For example, I have say a subroutine play_with_hash:
sub play_with_hash
{
my( $var1, $var2, %my_hash ) = @_;
#do stuff with %my_hash
...........
}
Then I want to call the subroutine... (1 Reply)

I want to store a bunch of pthread_t types in a hash table, but since pthread_t is not an integer value, I cannot hash it. I was hoping to store a unique nonzero as key 0 for each thread with thread-specific data ala pthread_key_create/pthread_setspecific, but but as it turns out only the first... (2 Replies)

I have a script with dynamic hash of hashes , and I want to print the entire hash (with all other hashes).
Itried to do it recursively by checking if the current key is a hash and if yes call the current function again with refference to the sub hash.

Authen::Passphrase::NTHash(3pm) User Contributed Perl Documentation Authen::Passphrase::NTHash(3pm)
NAME
Authen::Passphrase::NTHash - passphrases using the NT-Hash algorithm
SYNOPSIS
use Authen::Passphrase::NTHash;
$ppr = Authen::Passphrase::NTHash->new(
hash_hex => "7f8fe03093cc84b267b109625f6bbf4b");
$ppr = Authen::Passphrase::NTHash->new(
passphrase => "passphrase");
$ppr = Authen::Passphrase::NTHash->from_crypt(
'$3$$7f8fe03093cc84b267b109625f6bbf4b');
$ppr = Authen::Passphrase::NTHash->from_rfc2307(
'{MSNT}7f8fe03093cc84b267b109625f6bbf4b');
$hash = $ppr->hash;
$hash_hex = $ppr->hash_hex;
if($ppr->match($passphrase)) { ...
$passwd = $ppr->as_crypt;
$userPassword = $ppr->as_rfc2307;
DESCRIPTION
An object of this class encapsulates a passphrase hashed using the NT-Hash function. This is a subclass of Authen::Passphrase, and this
document assumes that the reader is familiar with the documentation for that class.
The NT-Hash scheme is based on the MD4 digest algorithm. Up to 128 characters of passphrase (characters beyond the 128th are ignored) are
represented in Unicode, and hashed using MD4. No salt is used.
Warning: MD4 is a weak hash algorithm by current standards, and the lack of salt is a design flaw in this scheme. Use this for
compatibility only, not by choice.
CONSTRUCTORS
Authen::Passphrase::NTHash->new(ATTR => VALUE, ...)
Generates a new passphrase recogniser object using the NT-Hash algorithm. The following attributes may be given:
hash
The hash, as a string of 16 bytes.
hash_hex
The hash, as a string of 32 hexadecimal digits.
passphrase
A passphrase that will be accepted.
Either the hash or the passphrase must be given.
Authen::Passphrase::NTHash->from_crypt(PASSWD)
Generates a new NT-Hash passphrase recogniser object from a crypt string. Two forms are accepted. In the first form, the he crypt
string must consist of "$3$$" (note the extra "$") followed by the hash in lowercase hexadecimal. In the second form, the he crypt
string must consist of "$NT$" followed by the hash in lowercase hexadecimal.
Authen::Passphrase::NTHash->from_rfc2307(USERPASSWORD)
Generates a new NT-Hash passphrase recogniser object from an RFC 2307 string. Two forms are accepted. In the first form, the string
must consist of "{MSNT}" followed by the hash in hexadecimal; case is ignored. In the second form, the string must consist of
"{CRYPT}" (case insensitive) followed by an acceptable crypt string.
METHODS
$ppr->hash
Returns the hash value, as a string of 16 bytes.
$ppr->hash_hex
Returns the hash value, as a string of 32 hexadecimal digits.
$ppr->match(PASSPHRASE)
$ppr->as_crypt
$ppr->as_rfc2307
These methods are part of the standard Authen::Passphrase interface.
