FAQ
What is Base64 encoding?
Base64 is an encoding scheme that represents binary data using 64 printable characters. It is commonly used to transmit or store binary data or special characters in text-based environments such as email, XML, and JSON, ensuring data is not accidentally modified or truncated during transmission.
Is Base64 a form of encryption? Is it secure?
No, Base64 is definitely not an encryption algorithm — it is merely a data encoding method. Anyone with Base64-encoded data can easily decode it back to its original content. Therefore, never use Base64 to "encrypt" passwords or other sensitive information.
