CVE-2025-40912 (2025-06-11)

CryptX for Perl before version 0.065 contains a dependency that may be susceptible to malformed unicode. CryptX embeds the tomcrypt library. The versions of that library in CryptX before 0.065 may be susceptible to CVE-2019-17362.

CVE-2025-40914 (2025-06-11)

Perl CryptX before version 0.087 contains a dependency that may be susceptible to an integer overflow. CryptX embeds a version of the libtommath library that is susceptible to an integer overflow associated with CVE-2023-36328.

CVE-2026-41564 (2026-04-23)

CryptX versions before 0.088 for Perl do not reseed the Crypt::PK PRNG state after forking. The Crypt::PK::RSA, Crypt::PK::DSA, Crypt::PK::DH, Crypt::PK::ECC, Crypt::PK::Ed25519 and Crypt::PK::X25519 modules seed a per-object PRNG state in their constructors and reuse it without fork detection. A Crypt::PK::* object created before `fork()` shares byte-identical PRNG state with every child process, and any randomized operation they perform can produce identical output, including key generation. Two ECDSA or DSA signatures from different processes are enough to recover the signing private key through nonce-reuse key recovery. This affects preforking services such as the Starman web server, where a Crypt::PK::* object loaded at startup is inherited by every worker process.

CVE-2018-25099 (2018-10-26)

A user can pass anything as the tag into gcm_decrypt_verify() and it will return decrypted plaintext.

NAME

Crypt::Digest::Tiger192 - Hash function Tiger-192 [size: 192 bits]

SYNOPSIS

### Functional interface:
use Crypt::Digest::Tiger192 qw( tiger192 tiger192_hex tiger192_b64 tiger192_b64u
                             tiger192_file tiger192_file_hex tiger192_file_b64 tiger192_file_b64u );

# calculate digest from string/buffer
$tiger192_raw  = tiger192('data string');
$tiger192_hex  = tiger192_hex('data string');
$tiger192_b64  = tiger192_b64('data string');
$tiger192_b64u = tiger192_b64u('data string');
# calculate digest from file
$tiger192_raw  = tiger192_file('filename.dat');
$tiger192_hex  = tiger192_file_hex('filename.dat');
$tiger192_b64  = tiger192_file_b64('filename.dat');
$tiger192_b64u = tiger192_file_b64u('filename.dat');
# calculate digest from filehandle
$tiger192_raw  = tiger192_file(*FILEHANDLE);
$tiger192_hex  = tiger192_file_hex(*FILEHANDLE);
$tiger192_b64  = tiger192_file_b64(*FILEHANDLE);
$tiger192_b64u = tiger192_file_b64u(*FILEHANDLE);

### OO interface:
use Crypt::Digest::Tiger192;

$d = Crypt::Digest::Tiger192->new;
$d->add('any data');
$d->addfile('filename.dat');
$d->addfile(*FILEHANDLE);
$result_raw  = $d->digest;     # raw bytes
$result_hex  = $d->hexdigest;  # hexadecimal form
$result_b64  = $d->b64digest;  # Base64 form
$result_b64u = $d->b64udigest; # Base64 URL Safe form

DESCRIPTION

Provides an interface to the Tiger192 digest algorithm.

EXPORT

Nothing is exported by default.

You can export selected functions:

use Crypt::Digest::Tiger192 qw(tiger192 tiger192_hex tiger192_b64 tiger192_b64u
                                    tiger192_file tiger192_file_hex tiger192_file_b64 tiger192_file_b64u);

Or all of them at once:

use Crypt::Digest::Tiger192 ':all';

FUNCTIONS

tiger192

Logically joins all arguments into a single string, and returns its Tiger192 digest encoded as a binary string.

$tiger192_raw = tiger192('data string');
#or
$tiger192_raw = tiger192('any data', 'more data', 'even more data');

tiger192_hex

Logically joins all arguments into a single string, and returns its Tiger192 digest encoded as a hexadecimal string.

$tiger192_hex = tiger192_hex('data string');
#or
$tiger192_hex = tiger192_hex('any data', 'more data', 'even more data');

tiger192_b64

Logically joins all arguments into a single string, and returns its Tiger192 digest encoded as a Base64 string, with trailing '=' padding.

$tiger192_b64 = tiger192_b64('data string');
#or
$tiger192_b64 = tiger192_b64('any data', 'more data', 'even more data');

tiger192_b64u

Logically joins all arguments into a single string, and returns its Tiger192 digest encoded as a Base64 URL Safe string (see RFC 4648 section 5).

$tiger192_b64url = tiger192_b64u('data string');
#or
$tiger192_b64url = tiger192_b64u('any data', 'more data', 'even more data');

tiger192_file

Reads file (defined by filename or filehandle) content, and returns its Tiger192 digest encoded as a binary string.

$tiger192_raw = tiger192_file('filename.dat');
#or
$tiger192_raw = tiger192_file(*FILEHANDLE);

tiger192_file_hex

Reads file (defined by filename or filehandle) content, and returns its Tiger192 digest encoded as a hexadecimal string.

$tiger192_hex = tiger192_file_hex('filename.dat');
#or
$tiger192_hex = tiger192_file_hex(*FILEHANDLE);

BEWARE: You have to make sure that the filehandle is in binary mode before you pass it as argument to the addfile() method.

tiger192_file_b64

Reads file (defined by filename or filehandle) content, and returns its Tiger192 digest encoded as a Base64 string, with trailing '=' padding.

$tiger192_b64 = tiger192_file_b64('filename.dat');
#or
$tiger192_b64 = tiger192_file_b64(*FILEHANDLE);

tiger192_file_b64u

Reads file (defined by filename or filehandle) content, and returns its Tiger192 digest encoded as a Base64 URL Safe string (see RFC 4648 section 5).

$tiger192_b64url = tiger192_file_b64u('filename.dat');
#or
$tiger192_b64url = tiger192_file_b64u(*FILEHANDLE);
