Frequently Asked Questions
Is Base64 encoding secure?
Base64 is encoding, not encryption. It's reversible and visible in plaintext. Use encryption for sensitive data.
Why use Base64?
Base64 converts binary data into text format, making it safe for transmission over text-only protocols.
What's the difference between encoding and encryption?
Encoding is reversible and not meant for security. Encryption is meant to protect data and requires keys.
