About Snefru Hash Algorithm

Snefru is a cryptographic hash function invented by Ralph Merkle in 1990. The name "Snefru" is derived from the Egyptian pharaoh Sneferu. It was one of the first dedicated hash functions to be proposed, and it introduced several innovative concepts in hash function design.

Snefru Hash Characteristics

⚠️ Security Note: While Snefru was innovative for its time, modern cryptanalysis has found vulnerabilities in both Snefru-128 and Snefru-256. For security-critical applications, consider using more modern hash functions like SHA-256, SHA-3, or BLAKE2.

Snefru Variants

Snefru comes in two main variants with different security levels and output sizes:

Snefru vs Other Hash Algorithms

Variant	Output Size	Security Level	Recommended Use
Snefru-128	128 bits	Broken	Non-security applications, legacy systems
Snefru-256	256 bits	Vulnerable	Non-critical applications, educational purposes

Algorithm	Year	Output Size	Security Status
Snefru	1990	128/256 bits	Broken/Vulnerable
MD5	1992	128 bits	Broken
SHA-1	1995	160 bits	Vulnerable
SHA-256	2001	256 bits	Secure

💡 Snefru was an important step in the evolution of cryptographic hash functions and introduced concepts that influenced later designs. While no longer secure for cryptographic use, it remains an interesting algorithm for study and non-security applications.
