Frequently Asked Questions (FAQ)
Is Base64 considered heavy encryption?
No. Base64 is strictly a binary-to-text encoding scheme. It does not secure or encrypt your data, it merely translates it into a uniform text format suitable for HTTP transfer.
Why are there equals signs (=) at the end of my Base64 string?
The equals signs serve as padding characters. Base64 divides data into 24-bit clusters. If your initial string falls short of closing a specific cluster, the architecture algorithm automatically appends padding to finalize the structure.
