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-2026-41565 (2026-05-28)

CryptX versions before 0.088_001 for Perl have a stack buffer overflow in four AEAD decrypt_verify helpers. The gcm_decrypt_verify, ccm_decrypt_verify, chacha20poly1305_decrypt_verify and eax_decrypt_verify XS routines copied the caller-supplied authentication tag into a fixed 144-byte stack buffer (MAXBLOCKSIZE) without checking the supplied length. A longer tag overwrites the stack past the buffer. Version 0.088 added the clamp to gcm_decrypt_verify, and 0.088_001 added it to the other three. Any caller of an affected helper that forwards an attacker-controlled tag longer than the buffer can trigger the overflow.

NAME

Crypt::Digest::RIPEMD160 - Hash function RIPEMD-160 [size: 160 bits]

SYNOPSIS

### Functional interface:
use Crypt::Digest::RIPEMD160 qw( ripemd160 ripemd160_hex ripemd160_b64 ripemd160_b64u
                             ripemd160_file ripemd160_file_hex ripemd160_file_b64 ripemd160_file_b64u );

# calculate digest from string/buffer
$ripemd160_raw  = ripemd160('data string');
$ripemd160_hex  = ripemd160_hex('data string');
$ripemd160_b64  = ripemd160_b64('data string');
$ripemd160_b64u = ripemd160_b64u('data string');
# calculate digest from file
$ripemd160_raw  = ripemd160_file('filename.dat');
$ripemd160_hex  = ripemd160_file_hex('filename.dat');
$ripemd160_b64  = ripemd160_file_b64('filename.dat');
$ripemd160_b64u = ripemd160_file_b64u('filename.dat');
# calculate digest from filehandle
$ripemd160_raw  = ripemd160_file(*FILEHANDLE);
$ripemd160_hex  = ripemd160_file_hex(*FILEHANDLE);
$ripemd160_b64  = ripemd160_file_b64(*FILEHANDLE);
$ripemd160_b64u = ripemd160_file_b64u(*FILEHANDLE);

### OO interface:
use Crypt::Digest::RIPEMD160;

$d = Crypt::Digest::RIPEMD160->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 RIPEMD160 digest algorithm.

EXPORT

Nothing is exported by default.

You can export selected functions:

use Crypt::Digest::RIPEMD160 qw(ripemd160 ripemd160_hex ripemd160_b64 ripemd160_b64u
                                    ripemd160_file ripemd160_file_hex ripemd160_file_b64 ripemd160_file_b64u);

Or all of them at once:

use Crypt::Digest::RIPEMD160 ':all';

FUNCTIONS

ripemd160

Logically joins all arguments into a single string, and returns its RIPEMD160 digest encoded as a binary string.

$ripemd160_raw = ripemd160('data string');
#or
$ripemd160_raw = ripemd160('any data', 'more data', 'even more data');

ripemd160_hex

Logically joins all arguments into a single string, and returns its RIPEMD160 digest encoded as a hexadecimal string.

$ripemd160_hex = ripemd160_hex('data string');
#or
$ripemd160_hex = ripemd160_hex('any data', 'more data', 'even more data');

ripemd160_b64

Logically joins all arguments into a single string, and returns its RIPEMD160 digest encoded as a Base64 string, with trailing '=' padding.

$ripemd160_b64 = ripemd160_b64('data string');
#or
$ripemd160_b64 = ripemd160_b64('any data', 'more data', 'even more data');

ripemd160_b64u

Logically joins all arguments into a single string, and returns its RIPEMD160 digest encoded as a Base64 URL Safe string (see RFC 4648 section 5).

$ripemd160_b64url = ripemd160_b64u('data string');
#or
$ripemd160_b64url = ripemd160_b64u('any data', 'more data', 'even more data');

ripemd160_file

Reads file (defined by filename or filehandle) content, and returns its RIPEMD160 digest encoded as a binary string.

$ripemd160_raw = ripemd160_file('filename.dat');
#or
$ripemd160_raw = ripemd160_file(*FILEHANDLE);

ripemd160_file_hex

Reads file (defined by filename or filehandle) content, and returns its RIPEMD160 digest encoded as a hexadecimal string.

$ripemd160_hex = ripemd160_file_hex('filename.dat');
#or
$ripemd160_hex = ripemd160_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.

ripemd160_file_b64

Reads file (defined by filename or filehandle) content, and returns its RIPEMD160 digest encoded as a Base64 string, with trailing '=' padding.

$ripemd160_b64 = ripemd160_file_b64('filename.dat');
#or
$ripemd160_b64 = ripemd160_file_b64(*FILEHANDLE);

ripemd160_file_b64u

Reads file (defined by filename or filehandle) content, and returns its RIPEMD160 digest encoded as a Base64 URL Safe string (see RFC 4648 section 5).

$ripemd160_b64url = ripemd160_file_b64u('filename.dat');
#or
$ripemd160_b64url = ripemd160_file_b64u(*FILEHANDLE);
