Python SHA512 Benchmark

README.md

super simple hash benchmark

---

• run a loop a half million times:
  • split a delimited string into 5 fields
  • strip invalid characters from each field with a regex
  • calculate a SHA3-512 hash and get the digest for each field (2.5 million hashes)

Environment:

• OS: Windows 11
• Runtime: Python 3.14
• CPU: 11th Gen Intel Core i7-1185G7 @ 3.0GHz

Results:
