Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII
string format. It is commonly used to embed images directly into HTML or CSS.
Is it secure to use Base64 for encryption?
No. Base64 is an encoding, not encryption. Anyone can decode it. Do not use it to hide
sensitive data.
Why is the encoded text longer than the original?
Base64 uses 4 characters to represent every 3 bytes of data, resulting in an approximate
33% increase in size.
