Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Weak Cryptographic Key: The library previously generated 2FA secret keys shorter than the cryptographically secure threshold of 128 bits under certain Google Authenticator compatibility settings, allowing for potential brute-force attacks against weak secrets.

Weak Cryptographic Algorithm: Secrets could fall below the 128-bit minimum key size requirement when specific compatibility flags bypassed key-length validation during secret key generation.

Information Disclosure: Generating QR codes via the Google Chart API implicitly transmitted sensitive 2FA TOTP secret keys to external Google servers, risking exposure of authentication secrets to third parties.
