Don't Roll Your Own Crypto: Why Developers Keep Failing at Encryption

Developers often mistakenly believe that using lower-level cryptography libraries avoids the risks of 'rolling their own crypto.' This article argues that many developers misunderstand cryptography, and even using existing libraries doesn't guarantee security if mistakes are made in protocol design or key management. The author presents real-world examples and stresses the importance of robust key management and the need for developers to deeply understand and have expert review of their cryptographic implementations.
