cpu command in Go, inspired by the Plan 9 cpu command (by u-root)
sha256-simd
Accelerate SHA256 computations in pure Go using AVX512, SHA Extensions for x86 and ARM64 for ARM. On AVX512 it provides an up to 8x improvement (over 3 GB/s per core). SHA Extensions give a performance boost of close to 4x over native. (by minio)

The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

SSH Tips and Tricks
What's the problem with FUSE?
Anyway, it needs a daemon on the remote system, but perhaps https://github.com/u-root/cpu is suitable. (I can't vouch for it, not having used it.)
The HTCondor batch system also provides something like that, but I don't know details, and it's probably not a separable component.

The Curious Case of MD5
BLAKE3 is faster than hardware accelerated SHA-2 because the tree mode used in BLAKE3 allows hashing parts of a single message in parallel (with SHA-2, parts of a single message have to be hashed one after another, and parallelism is only used in workloads where you process multiple messages at the same time).

Can I concatenate multiple non-crypto hash functions to reduce collision?
SHA256 is high quality but typically a bit slower. Next Go version will have faster SHA256 on some amd64 CPUs - until then you can try sha256-simd which offers the same.

I need to find a custom hexadecimal string that when encrypted starts with a certain specific hexadecimal string(77656e6f7469 in our case). I tried randomly generating strings encrpyting them and checking them, realized it would take too much time. Any help?
I am not sure, if you can achieve a reasonable speed with Python though. You probably have to use a compiled language or run it on GPU. I found this very fast implemenation in Go which uses special CPU instructions (the AVX2 or SHA extensionsm depending on your CPU model) to speed up the calculation: https://github.com/minio/sha256-simd
