1. Use non-capturing groups: Since you don't need the matched content from the groups for any specific purpose, you can use non-capturing groups by adding ?: after the opening parentheses, which can improve performance.
2. Use character class for the separator part: Instead of using multiple characters with alternation (e.g., =|>|:=|...), you can combine them into a character class.
3. Remove unnecessary escapes: You can remove unnecessary escape characters in the character class.

This optimized regex should provide better performance while maintaining the original intent of matching leaked keys and secrets. However, keep in mind that this regex is not foolproof and may still produce false positives or negatives.
