What is Base64?
Base64 is an encoding scheme used to convert binary data (like images or complex documents) into an ASCII string format. It translates the data into a radix-64 representation.
It is commonly used on the World Wide Web for transferring data over protocols that are designed to deal primarily with text-based data (like embedding image data directly into CSS or HTML files, or encoding email attachments).
Is Base64 Encryption?
No. Base64 is strictly an encoding format, not an encryption format. There is no mathematical key required to reverse it. Anyone who intercepts a Base64 string can instantly decode it back to plain text. You should never use Base64 to "hide" or secure passwords, API keys, or sensitive information.
