Frequently Asked Questions

Which hash algorithms are supported?

DevHelper supports six essential hash functions: MD5 (legacy compatibility), CRC32 (checksums), SHA-1 (legacy), SHA-256 (standard), SHA-384 (enhanced), and SHA-512 (maximum security) for various security requirements.

How secure is the AES-GCM encryption?

DevHelper uses AES-GCM-256, an industry-standard authenticated encryption algorithm that provides both confidentiality and authenticity. It's the same encryption used by major cloud providers and security systems.

What RSA key sizes are supported?

DevHelper supports both RSA-2048 (standard security) and RSA-4096 (enhanced security) key sizes, providing flexibility based on your security requirements and performance considerations.

Are cryptographic operations performed locally?

Yes! All cryptographic operations are performed locally on your Mac using iOS CryptoKit and Security framework. Your sensitive data never leaves your computer or gets sent to external servers.

Can I use these tools for production applications?

Absolutely! DevHelper uses industry-standard cryptographic libraries and algorithms suitable for production use. However, always follow security best practices and consider professional security audits for critical applications.

How do I generate secure keys?

DevHelper includes automatic key generation features that use cryptographically secure random number generators with proper entropy, ensuring generated keys meet security standards for production use.
