Question 1

What is Base64 encoding?

Accepted Answer

Base64 is a method of encoding binary data into ASCII text format. It uses 64 printable characters to represent data, making it safe for transmission over text-based protocols like email and HTTP. The encoding process converts 3 bytes of binary data into 4 Base64 characters.

Question 2

When should I use Base64 encoding?

Accepted Answer

Base64 encoding is commonly used to transmit binary data in JSON APIs, embed images in HTML/CSS, send files via email, and store binary data in text databases. It's also useful for encoding authentication credentials and creating data URIs for images and other media.

Question 3

Is Base64 secure for passwords?

Accepted Answer

No, Base64 is NOT encryption. It's simply an encoding scheme that can be easily reversed. Never use Base64 alone to secure passwords or sensitive data. Always use proper cryptographic algorithms like bcrypt, PBKDF2, or Argon2 for password hashing, and use AES or other encryption standards for sensitive information.
