FSB (Family of Secure Binaries) is a cryptographic hash function family that was a candidate in the NIST SHA-3 competition. It is based on the syndrome decoding problem and provides strong security guarantees with efficient implementation characteristics.
✅ Security Strength: FSB is considered cryptographically secure and is based on well-studied mathematical problems. It provides strong collision resistance and preimage resistance properties.
| Variant | Output Size | Security Level | Common Uses |
|---|---|---|---|
| FSB-160 | 160 bits (40 hex chars) | Medium | Legacy compatibility |
| FSB-224 | 224 bits (56 hex chars) | Strong | General purpose hashing |
| FSB-256 | 256 bits (64 hex chars) | Strong | Cryptographic applications |
| FSB-384 | 384 bits (96 hex chars) | Very Strong | High-security systems |
| FSB-512 | 512 bits (128 hex chars) | Very Strong | Maximum security applications |
FSB uses a compression function based on regular bipartite graphs and employs the syndrome decoding problem from coding theory. The algorithm processes input messages in blocks and produces a fixed-length output through multiple rounds of compression.
Security reductions to well-studied problems in coding theory
Fast implementation with good performance characteristics
Multiple output sizes for different security requirements
💡 Note: While FSB is a strong cryptographic hash function, for maximum compatibility consider using SHA-256 or SHA-3 in production systems, as they are more widely supported in standard libraries and frameworks.
