常见问题
When is Base64 encoding used?+
Base64 is used to represent binary data as ASCII text. Common uses include embedding images in HTML/CSS, encoding email attachments (MIME), transmitting data in URLs, and storing binary data in JSON or databases that only support text.
Is Base64 encryption?+
No! Base64 is encoding, not encryption. It's completely reversible by anyone - it provides zero security. For protecting sensitive data, use proper encryption like AES instead.
