# sha256-simd |
||||
|
||||
Accelerate SHA256 computations in pure Go for both Intel (AVX2, AVX, SSE) as well as ARM (arm64) platforms. |
||||
|
||||
## Introduction |
||||
|
||||
This package is designed as a drop-in replacement for `crypto/sha256`. For Intel CPUs it has three flavors for AVX2, AVX and SSE whereby the fastest method is automatically chosen depending on CPU capabilities. For ARM CPUs with the Cryptography Extensions advantage is taken of the SHA2 instructions resulting in a massive performance improvement. |
||||
|
||||
This package uses Golang assembly and as such does not depend on cgo. The Intel versions are based on the implementations as described in "Fast SHA-256 Implementations on Intel Architecture Processors" by J. Guilford et al. |
||||
|
||||
## Performance |
||||
|
||||
Below is the speed in MB/s for a single core (ranked fast to slow) as well as the factor of improvement over `crypto/sha256` (when applicable). |
||||
|
||||
| Processor | Package | Speed | Improvement | |
||||
| --------------------------------- | ---------------------------- | -----------:| -----------:| |
||||
| 1.2 GHz ARM Cortex-A53 | minio/sha256-simd (ARM64) | 638.2 MB/s | 105x | |
||||
| 2.4 GHz Intel Xeon CPU E5-2620 v3 | minio/sha256-simd (AVX2) (*) | 355.0 MB/s | 1.88x | |
||||
| 2.4 GHz Intel Xeon CPU E5-2620 v3 | minio/sha256-simd (AVX) | 306.0 MB/s | 1.62x | |
||||
| 2.4 GHz Intel Xeon CPU E5-2620 v3 | minio/sha256-simd (SSE) | 298.7 MB/s | 1.58x | |
||||
| 2.4 GHz Intel Xeon CPU E5-2620 v3 | crypto/sha256 | 189.2 MB/s | | |
||||
| 1.2 GHz ARM Cortex-A53 | crypto/sha256 | 6.1 MB/s | | |
||||
|
||||
(*) Measured with the "unrolled"/"demacro-ed" AVX2 version. Due to some Golang assembly restrictions the AVX2 version that uses `defines` loses about 15% performance. The optimized version is contained in the git history so for maximum speed you want to do this after getting: `git cat-file blob 586b6e > sha256blockAvx2_amd64.s` (or vendor it for your project; see [here](https://github.com/minio/sha256-simd/blob/13b11bdf9b0580a756a111492d2ae382bab7ec79/sha256blockAvx2_amd64.s) to view it in its full glory). |
||||
|
||||
See further down for detailed performance. |
||||
|
||||
## Comparison to other hashing techniques |
||||
|
||||
As measured on Intel Xeon (same as above) with AVX2 version: |
||||
|
||||
| Method | Package | Speed | |
||||
| ------- | -------------------| --------:| |
||||
| BLAKE2B | [minio/blake2b-simd](https://github.com/minio/blake2b-simd) | 851 MB/s | |
||||
| MD5 | crypto/md5 | 607 MB/s | |
||||
| SHA1 | crypto/sha1 | 522 MB/s | |
||||
| SHA256 | minio/sha256-simd | 355 MB/s | |
||||
| SHA512 | crypto/sha512 | 306 MB/s | |
||||
|
||||
asm2plan9s |
||||
---------- |
||||
|
||||
In order to be able to work more easily with AVX2/AVX instructions, a separate tool was developed to convert AVX2/AVX instructions into the corresponding BYTE sequence as accepted by Go assembly. See [asm2plan9s](https://github.com/minio/asm2plan9s) for more information. |
||||
|
||||
Why and benefits |
||||
---------------- |
||||
|
||||
One of the most performance sensitive parts of [Minio](https://minio.io) server (object storage [server](https://github.com/minio/minio) compatible with Amazon S3) is related to SHA256 hash sums calculations. For instance during multi part uploads each part that is uploaded needs to be verified for data integrity by the server. Likewise in order to generated pre-signed URLs check sums must be calculated to ensure their validity. |
||||
|
||||
Other applications that can benefit from enhanced SHA256 performance are deduplication in storage systems, intrusion detection, version control systems, integrity checking, etc. |
||||
|
||||
ARM SHA Extensions |
||||
------------------ |
||||
|
||||
The 64-bit ARMv8 core has introduced new instructions for SHA1 and SHA2 acceleration as part of the [Cryptography Extensions](http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ddi0501f/CHDFJBCJ.html). Below you can see a small excerpt highlighting one of the rounds as is done for the SHA256 calculation process (for full code see [sha256block_arm64.s](https://github.com/minio/sha256-simd/blob/master/sha256block_arm64.s)). |
||||
|
||||
``` |
||||

||||
sha256h2 q3, q4, v9.4s |
||||
