Frequently Asked Questions

What key size should I use?
256-bit keys are recommended for most applications as they provide excellent security. Use 128-bit for legacy systems, 512-bit for maximum security or when required by specific standards.
What's the difference between Base64 and URL-Safe Base64?
URL-Safe Base64 replaces + with -, / with _, and removes padding (=). This makes keys safe to use in URLs, filenames, and environment variables without encoding issues.
Are these keys cryptographically secure?
Yes! The tool uses the Web Crypto API's crypto.getRandomValues() which provides cryptographically secure pseudorandom numbers suitable for cryptographic purposes.
How should I store these keys?
Store keys in environment variables, secure key management systems, or encrypted configuration files. Never commit keys to version control or share them in plain text.
Can I use these keys for production systems?
Yes, these keys are suitable for production use. However, implement proper key rotation, access controls, and follow security best practices for your specific use case.
