Source
Snefru.256.cs

Computes a 256-bit (32-byte) hash using the Snefru hash algorithm by Ralph Merkle. This class cannot be inherited.

Examples

using Bodu.Security.Cryptography;

using var snefru = new Snefru256();
byte[] digest = snefru.ComputeHash(legacyMessage);

Remarks

Snefru256 maintains an 8-word internal state and absorbs input in 32-byte blocks into a 512-bit working buffer, applying 8 rounds of S-box substitution and word rotation per block. On finalization the state is XOR-folded from the permuted buffer and serialized in big-endian byte order. See Snefru for shared background.

Parameters at a glance.

  • Output size: 256 bits (32 bytes).
  • Block size: 32 bytes; 8-word internal state; 8 rounds per block.
  • Status: broken - practical collision attacks are known.

When to choose Snefru256. Academic study and legacy interop only. For new security-sensitive 256-bit hashing use SHA-256 or Blake2b; for fingerprinting use a 256-bit non-cryptographic hash from Bodu.IO.Hashing.

important

Snefru is considered broken and not suitable for password hashing, digital signatures, or secure data integrity checks.
