Pattern

regexPY
(?:sk|pk|rk)_(?:test|live)_[A-Za-z0-9]{24,}   (flags: g)

Python (re) code

pyPython
import re

pattern = re.compile(r"(?:sk|pk|rk)_(?:test|live)_[A-Za-z0-9]{24,}")
input_text = "Use sk_live_4eC39HqLyjWDarjtT1zdp7dc for prod"
for m in pattern.finditer(input_text):
    print(m.group(0))

Stdlib `re` module — no third-party dependency. Works on Python 3.6+.

How the pattern works

(?:sk|pk|rk) matches one of the three key types. _(?:test|live)_ matches the mode separator. [A-Za-z0-9]{24,} matches the random suffix — Stripe's keys are at least 24 characters, sometimes longer for restricted keys. The pattern catches keys exposed in source code, logs, or chat transcripts.
