What is Base64 encoding?

Base64 is a binary-to-text encoding scheme that converts binary data into ASCII characters. It's commonly used to transmit data safely over text-based protocols like HTTP and email.

Is Base64 encoding the same as encryption?

No. Base64 is an encoding scheme, not encryption. Anyone can decode Base64 data. It's meant for data transport, not security.
