Note: Results are machine-specific and may vary between systems. Run benchmarks locally for your specific hardware.

BenchmarkDotNet measurements for all hash algorithm implementations in CryptoHives.Foundation.Security.Cryptography. Each algorithm is benchmarked across representative payload sizes (128 bytes through 128 KiB) to capture both latency and throughput characteristics.

Implementations are compared against:

• OS — .NET's built-in System.Security.Cryptography (backed by CNG/OpenSSL)
• BouncyCastle — BouncyCastle C# library
• Native — Platform-specific native libraries (e.g., blake3-dotnet)
• Managed — CryptoHives managed implementation (scalar)
• SIMD — CryptoHives SIMD variants (SSE2, SSSE3, AVX2, AVX-512F)

SHA-2 Family

The OS SHA-256/SHA-512 implementations leverage SHA-NI hardware instructions (available on AMD Zen+ and Intel Ice Lake+), providing ~4.5× speedup over any software implementation. For pure managed code, CryptoHives outperforms BouncyCastle by approximately 13% through loop unrolling and hardcoded round constants.

Key observations:

• OS: Uses SHA-NI hardware acceleration
• Managed: Optimized scalar with unrolled rounds
• BouncyCastle: Reference scalar implementation

Keccak-derived Families

The managed Keccak core uses an optimized scalar implementation that outperforms both the OS-provided SHA-3 and SIMD variants (AVX2/AVX-512F). This is unusual—typically SIMD accelerates cryptographic operations—but Keccak's irregular permutation structure doesn't map efficiently to SIMD lanes.

Key observations:

• Managed scalar is ~30% faster than OS SHA-3 and 25–35% faster than SIMD variants
• SIMD implementations (AVX2/AVX-512F) are provided but disabled by default
• All Keccak-derived algorithms (SHA-3, SHAKE, cSHAKE, TurboSHAKE, KT) share the same optimized core

BLAKE2 Family

BouncyCastle leads the BLAKE2 benchmarks due to highly optimized native code. The managed AVX2/SSSE3/SSE2 SIMD implementations are competitive (within ~15% of BouncyCastle or even), while the scalar fallback is significantly slower (~3.5× for BLAKE2b, ~4× for BLAKE2s).

Key observations:

• BouncyCastle: Highly optimized reference
• Managed AVX2: Competitive SIMD implementation
• Managed scalar: Fallback for non-SIMD platforms

BLAKE3

BLAKE3 is a modern hash function designed for extreme parallelism and speed. It can leverage tree hashing to process multiple chunks simultaneously, making it ideal for hashing large files. The Native (Rust) variant uses blake3-dotnet, which wraps the official Rust implementation via P/Invoke—this is the fastest option and recommended when native dependencies are acceptable.

The managed CryptoHives implementation uses SSSE3 SIMD instructions with optimized state management. At small inputs (128B-1kb), the SSSE3 path is ~1.4× slower than the native Rust implementation and ~9× faster than BouncyCastle. At large inputs (128KB), the gap widens to ~12× because the native implementation parallelizes chunk compression across SIMD lanes (AVX2/AVX-512 hash_many), while the managed version processes chunks sequentially.

KMAC Family

KMAC (Keccak Message Authentication Code) is defined in NIST SP 800-185 and provides a Keccak-based keyed hash function. Like SHA-3, SHAKE, and cSHAKE, KMAC shares the same optimized Keccak permutation core, benefiting from the scalar optimizations described in the Keccak section above.

The managed CryptoHives implementation is the fastest at all input sizes, outperforming the OS-provided KMAC by ~30% and BouncyCastle by ~48%. This advantage comes from the highly optimized scalar Keccak core that benefits both the hash computation and the KMAC-specific cSHAKE encoding overhead.

Legacy Algorithms

MD5 and SHA-1 are provided exclusively for backward compatibility with legacy protocols and file formats (e.g., verifying old checksums, interoperability with legacy systems). Both algorithms have known cryptographic weaknesses:

• MD5: Vulnerable to collision attacks since 2004; should not be used for security
• SHA-1: Collision attacks demonstrated in 2017 (SHAttered); deprecated by NIST

The OS implementations are fastest due to potential hardware acceleration. The managed implementations prioritize correctness and portability over optimization, as these algorithms should only be used for non-security purposes.

Regional Standards

These algorithms serve regulatory compliance requirements in specific jurisdictions. While not commonly used in Western applications, they are mandatory in their respective regions:

Algorithm	Region	Use Case
SM3	China	Required for Chinese government and financial systems (GB/T 32905-2016)
Streebog	Russia	Russian federal standard GOST R 34.11-2012, required for government communications
Kupyna	Ukraine	Ukrainian national standard DSTU 7564:2014, required for government systems
LSH	South Korea	Korean national standard KS X 3262, approved by KCMVP
Whirlpool	ISO/NESSIE	European cryptographic standard (ISO/IEC 10118-3)
RIPEMD-160	Europe/Crypto	Used in Bitcoin address generation and some European standards

The managed Streebog implementation is notably faster (1.4–1.8×) than reference implementations while using less memory—important for embedded systems in constrained environments. The managed Kupyna implementation uses T-table optimization (combining SubBytes, ShiftBytes, and MixColumns) to outperform BouncyCastle by 30–45%.

XOF Mode

XOF (Extendable Output Function) benchmarks measure the full absorb-then-squeeze cycle: the input is absorbed and an output of equal size is squeezed. The benchmark method is AbsorbSqueeze. All CryptoHives XOF implementations are zero-allocation regardless of output size. BouncyCastle's XOF implementations allocate an internal output buffer proportional to the squeezed length (e.g., ~150 KB for a 128 KiB squeeze), making them unsuitable for high-frequency streaming use.

Note

On Windows x64, the Managed Keccak scalar path outperforms BouncyCastle at small and medium sizes — the opposite of Apple M4, where BouncyCastle's Keccak is marginally faster due to pipelining characteristics of Apple Silicon. Windows CNG exposes a native SHAKE128, SHAKE256, KMAC128, and KMAC256 XOF interface; it does not expose cSHAKE as a standalone API.

SHAKE Family

SHAKE128 and SHAKE256 (FIPS 202) are variable-output-length extensions of the SHA-3 permutation with security strengths of 128 and 256 bits. SHAKE128 uses a 1344-bit rate (21 lanes) while SHAKE256 uses a 1088-bit rate — making SHAKE128 ~14% faster for the same output size.

On AMD Ryzen 5 7600X, CryptoHives Managed is the fastest at small inputs: ~47% faster than BouncyCastle at 128 B for SHAKE128, and ~49% faster for SHAKE256. At 8 KiB and beyond, OS Native (Windows CNG) takes the lead, presumably benefiting from a wider SIMD path in CNG's Keccak implementation. BouncyCastle is slowest across all sizes and allocates output-proportional buffers (~150 KB at 128 KiB squeeze).

Key observations:

• Managed: Fastest at ≤ 1 KiB (~47–49% faster than BC); zero-allocation
• OS Native: Fastest at ≥ 8 KiB; zero-allocation
• BouncyCastle: Slowest; allocates ~150 KB at 128 KiB squeeze; ~9% slower than Managed at 128 KiB
• SHAKE128 ~16% faster than SHAKE256 at 128 KiB due to wider rate

cSHAKE Family

cSHAKE128 and cSHAKE256 (NIST SP 800-185) add domain separation via function-name and customization strings on top of SHAKE. Windows CNG does not expose a cSHAKE XOF API, so only Managed and BouncyCastle are available here.

The CryptoHives Managed implementation leads at all sizes: ~47% faster than BouncyCastle at 128 B for cSHAKE128, and still ~9% faster at 128 KiB. The advantage at large sizes is distinct from the plain SHAKE results where OS Native overtook Managed — and shows the penalty of BouncyCastle's allocating XOF path. Both Managed and BouncyCastle are slightly slower than their plain SHAKE counterparts due to the encoding of customization strings during initialization.

Key observations:

• Managed: Fastest at all sizes; ~47% faster than BC at 128 B, ~9% at 128 KiB; zero-allocation
• BouncyCastle: Allocates ~150 KB at 128 KiB squeeze
• No OS Native available for cSHAKE on Windows

KMAC Family (XOF)

KMAC128 XOF and KMAC256 XOF (NIST SP 800-185) are keyed variable-length PRFs based on cSHAKE. Windows CNG exposes KMAC XOF natively; it allocates a fixed 32 B per call for the output descriptor.

Managed leads at small sizes: ~59% faster than BouncyCastle at 128 B for KMAC128, ~58% for KMAC256. OS Native displaces Managed at ≥ 8 KiB (~12% faster than Managed at that crossover point). BouncyCastle is slowest throughout and allocates ~150 KB at 128 KiB.

Key observations:

• Managed: Fastest at ≤ 1 KiB; zero-allocation
• OS Native: Fastest at ≥ 8 KiB; allocates a fixed 32 B per call
• BouncyCastle: Slowest; allocates 128 B at small sizes, ~150 KB at 128 KiB

KangarooTwelve Family (XOF)

KangarooTwelve (KT128 / KT256) are tree-hashing XOFs based on the Keccak permutation with 12 rounds (vs 24 for full SHA-3). The reduced-round design yields ~2× throughput over SHAKE128 while maintaining 128-bit security. No external competitor implementations are available for comparison.

On AMD Ryzen 5 7600X, KT128 XOF is ~75% faster than SHAKE128 Managed at 128 B, and ~45% faster at 128 KiB. The larger throughput advantage at bulk sizes reflects the 12-round saving being more impactful when the permutation dominates. KT256 uses the narrower cSHAKE256 rate and is slightly slower.

Key observations:

• KT128: ~75% faster than SHAKE128 Managed at 128 B; ~45% faster at 128 KiB
• KT256: ~19% slower than KT128 at 128 KiB due to narrower rate (1088-bit vs 1344-bit)
• Zero-allocation; no BouncyCastle or OS comparison available

TurboSHAKE Family (XOF)

TurboSHAKE128 and TurboSHAKE256 (IETF RFC 9562) use 12 Keccak rounds with a simplified padding scheme and a plain XOF interface with no tree-hashing overhead. They are the simplest and fastest Keccak-family XOFs available.

On AMD Ryzen 5 7600X, TurboSHAKE128 XOF and KT128 XOF perform nearly identically across all payload sizes — essentially the same throughput with TurboSHAKE having a slightly simpler API. TurboSHAKE128 is the fastest Keccak-based XOF on this platform.

Key observations:

• TurboSHAKE128 and KT128 deliver effectively equal throughput on x64
• Fastest Keccak XOF on this platform at both small and large sizes
• Zero-allocation; no OS or BouncyCastle comparison available

BLAKE3 (XOF)

BLAKE3 XOF produces output of arbitrary length using the same ChaCha-based compression function but extending the tree hashing to output-reader mode. On x64, CryptoHives ships three implementation tiers: Native (Rust via blake3-dotnet, uses AVX2/AVX-512 hash-many parallelism), Ssse3 (SSSE3-based parallel chunk generation), and Managed (scalar).

The Native Rust implementation dominates at all sizes: ~12× faster than Managed at 128 KiB, and ~15.7× faster than BouncyCastle. BouncyCastle's BLAKE3 XOF is extremely slow — it generates extended output sequentially without any tree parallelism and allocates only a fixed 56 B per call. Ssse3 provides a middle tier: ~4.3× faster than Managed at 128 KiB.

Key observations:

• Native: ~12× faster than Managed at 128 KiB; ~15.7× faster than BC; zero-allocation
• Ssse3: ~4.3× faster than Managed at 128 KiB; zero-allocation
• Managed: ~2.4× faster than BC at 128 KiB; zero-allocation
• BouncyCastle: Slowest by a large margin; allocates only 56 B (BC does not buffer large output slabs)
• Native tree hash-many exploits AVX-512 on capable CPUs; falls back to AVX2 on Ryzen 5 7600X

Ascon-XOF128

Ascon-XOF128 (NIST Lightweight Cryptography standard 2023) is the XOF variant of the Ascon family using the same 320-bit permutation as Ascon-Hash256. It requires a 12-round permutation call per 16 bytes of rate, making it inherently slower than SHAKE/BLAKE XOFs for large outputs.

On AMD Ryzen 5 7600X, the CryptoHives Managed implementation is ~33% faster than BouncyCastle across all sizes. Zero allocation on both paths.

Key observations:

• Managed: ~33% faster than BouncyCastle at all sizes; zero-allocation
• Throughput ~3× slower than SHAKE128 Managed at 128 KiB due to the narrow 128-bit rate
• Designed for memory-constrained environments, not bulk throughput
