💡 HAVAL implementation example in PHP:

$hash = hash('haval256,5', 'your_text');

# Generate HAVAL-256 hash with 5 rounds in PHP

$hash = hash('haval128,3', 'your_text');

# Generate HAVAL-128 hash with 3 rounds in PHP

About HAVAL Hash Algorithm

HAVAL (Hash of Variable Length) is a cryptographic hash function that produces hash values of 128, 160, 192, 224, or 256 bits in length. It was designed by Yuliang Zheng, Josef Pieprzyk, and Jennifer Seberry in 1992 as an extension of the MD5 algorithm with enhanced security features.

HAVAL Key Features

⚠️ Security Note: While HAVAL with 5 rounds remains relatively secure, some attacks have been demonstrated against versions with fewer rounds. For maximum security, use HAVAL with 5 rounds and 256-bit output, or consider modern alternatives like SHA-256 or SHA-3.

HAVAL Variants and Security

Variant	Output Size	Rounds	Security Status
HAVAL-128,3	128 bits	3	Vulnerable
HAVAL-128,4	128 bits	4	Weak
HAVAL-160,5	160 bits	5	Relatively Secure
HAVAL-192,5	192 bits	5	Secure
HAVAL-256,5	256 bits	5	Most Secure

Technical Details

HAVAL Algorithm Structure

Message preprocessing with padding to 1024-bit blocks
Uses eight 32-bit working variables (A through H)
Each round consists of 32 steps with different Boolean functions
Final output is truncated to the selected length (128-256 bits)

💡 For optimal security, use HAVAL-256,5 which provides 256-bit output with 5 rounds of processing. This variant offers excellent collision resistance and is suitable for most non-cryptographic applications.
