Frequently Asked Questions
What is Base64 encoding used for?
Base64 encodes binary data as ASCII text, making it safe to transmit over text-based protocols like HTTP, email, or JSON. It is commonly used in data URIs, email attachments, and API authentication.
Does Base64 encryption secure my data?
No. Base64 is an encoding scheme, not encryption. It is easily reversible and should never be used to protect sensitive data. Use proper encryption (AES, RSA) for security.
