Eric Sesterhenn	7221fc4d4b	Delete unused code (#9350 ) * Delete unused code CryptoEngine::clearKeys() is not used in the code base, therefore this cleanup removes the code. It might give casual reviewers the impression, that keys are wiped. Since the code uses memset() which might be optimized away by the compiler, using the code might not even cause the memory to be wiped. * Update CryptoEngine.cpp Fix stray newline, this is the only thing that I can come up with that might confuse the linter. --------- Co-authored-by: Jason P <applewiz@mac.com>	2026-01-24 05:19:19 -06:00
