About Hash Functions & Algorithms
What are Hash Functions?
Hash functions are mathematical algorithms that convert input data of any size into a fixed-size string of characters. They are widely used for data integrity verification, password storage, digital signatures, and checksums.
Supported Algorithms (15 Total):
Legacy MD Family:
- MD4: 128-bit hash, cryptographically broken but historically important (js-md4 library)
- MD5: 128-bit hash, fast but cryptographically broken (enhanced native implementation)
SHA-2 Family:
- SHA-1: 160-bit hash, deprecated for security applications (Web Crypto API)
- SHA-224: 224-bit SHA-2 variant, truncated SHA-256 (js-sha256 library)
- SHA-256: 256-bit hash, currently secure and widely recommended (Web Crypto API)
- SHA-384: 384-bit hash, truncated SHA-512 (Web Crypto API)
- SHA-512: 512-bit hash, strongest in SHA-2 family (Web Crypto API)
SHA-3 Family:
- SHA3-224: 224-bit SHA-3 variant, quantum-resistant (js-sha3 library)
- SHA3-256: 256-bit SHA-3 variant, recommended for new applications (js-sha3 library)
- SHA3-384: 384-bit SHA-3 variant, higher security (js-sha3 library)
- SHA3-512: 512-bit SHA-3 variant, maximum security (js-sha3 library)
Checksums & Specialized:
- CRC16: 16-bit cyclic redundancy check, CRC-16-CCITT standard (enhanced native implementation)
- CRC32: 32-bit cyclic redundancy check, IEEE 802.3 standard (enhanced native implementation)
- Adler32: 32-bit checksum, RFC 1950 specification (enhanced native implementation)
- NTLM: Windows NT LAN Manager hash, proper MD4-based implementation (js-md4 library)
Implementation Quality:
✓ Web Crypto API (Browser Native):
- • SHA-1, SHA-256, SHA-384, SHA-512
- • Maximum performance and security
- • Hardware acceleration when available
- • Industry standard compliance
✓ Specialized Libraries:
- • SHA-3 family (js-sha3 library)
- • MD4 and NTLM (js-md4 library)
- • SHA-224 (js-sha256 library)
- • Verified against test vectors
Enhanced Native Implementations:
MD5: Complete RFC 1321 compliant implementation with proper UTF-8 encoding
CRC32: IEEE 802.3 standard polynomial (0xEDB88320) for file integrity
CRC16: CRC-16-CCITT standard implementation (polynomial 0x1021) for telecommunications
Adler32: RFC 1950 specification for zlib compression
Common Use Cases:
- • File integrity verification and checksums
- • Password hashing and authentication systems
- • Digital signatures and certificates
- • Blockchain and cryptocurrency applications
- • Data deduplication and caching systems
- • Software distribution verification
- • Forensic analysis and evidence tracking
- • Network protocol integrity checks
Security Recommendations:
- • Use SHA-256, SHA-384, SHA-512 for new cryptographic applications
- • Consider SHA-3 algorithms for future-proofing against quantum attacks
- • Avoid MD4, MD5, and SHA-1 for security-critical applications
- • Use CRC32/Adler32 only for error detection, not security
- • Always use salt when hashing passwords
- • NTLM is deprecated, use modern authentication methods
- • Prefer Web Crypto API implementations for security purposes
